Chapter 3. Configuration

From the Configuration area, you can specify operating parameters for the CloudForms Management Engine infrastructure, view diagnostic information, and analytics on the servers. The accordion menu shows your CloudForms Management Engine infrastructure at the enterprise, zone, and server levels. There are three main areas.

  • Settings enable you to modify the configuration of your CloudForms Management Engine infrastructure. You can also create analysis profiles and schedules for these profiles.
  • Diagnostics displays the status of your servers and their roles and provides access to logs.

3.1. Settings

Under Configure → Configuration, then in the Settings accordion, you have a hierarchy of the configurable items in your CloudForms Management Engine architecture. At the top level, you have Settings including users, LDAP Groups, account roles, capacity and utilization collection, tag categories, values, and imports, custom variable imports, and license uploads. When you click on Settings and expand it, you can configure Analysis Profiles, Zones, and Schedules.

2041

When you go the Settings area, you are automatically taken to the server list under Zones.

3.1.1. Regions

Use Regions for centralizing data which is collected from public and private virtualization environments. A region is ultimately represented as a single database for the VMDB. Regions are particularly useful when multiple geographical locations need to be managed as they enable all the data collection to happen at each particular location and avoids data collection traffic across slow links between networks.

When multiple regions are being used, each with their own unique ID, a master region can be created to centralize the data of all the children regions into a single master database. To do this, configure each child region to replicate its data to the master region database (Red Hat recommends use of region 99). This parent and child region is a one-to-many relationship.

Regions can contain multiple zones, which in turn contain appliances. Zones are used for further segregating network traffic along with enabling failover configurations. Each appliance has the capability to be configured for a number of specialized server roles. These roles are limited to the zone containing the appliance they run on.

Only one failover type of each server role can run in a zone. If multiple appliances have the same failover role, the extras are used as backups that activate only if the primary appliance fails. Non-failover server roles can run on multiple appliances simultaneously in a zone, so resources can be adjusted according to the workload those roles are responsible for.

The following diagram demonstrates an example of the multiple regions working together in a CloudForms environment.

7151

The Master appliance is located in Chicago and contains a master region and a subregion that manages the worker appliances. The Mahwah technology center contains a single subregion that manages two zones. Likewise the San Diego technology center contains a single subregion managing a single zone.

Note
  • Replicating a parent region to a higher-level parent is not supported.
  • Parent regions can be configured after the child regions are online.

The following diagram provides a closer look at a region: 7150

In this region, we have several Red Hat CloudForms appliances acting as UI nodes and worker nodes. These worker nodes execute tasks on the providers in your environment. The Region also uses a region database that reports to a master database on the main Red Hat CloudForms appliance. All appliances can connect to the authentication services (Active Directory, LDAP, Identity Management), outgoing mail (SMTP), and network services (SNMP).

3.1.1.1. Region Scope

Regions are used to consolidate data from multiple VMDBs to a central database. The database at the top level, the master VMDB, cannot be used for operational tasks such as SmartState Analysis or Capacity and Utilization data collection. It is intended for use as a reporting database that includes all information across multiple subordinate regions. The subordinate regions replicate their information to the master.

Note

The subordinate regions are not aware of each other from a database perspective. You cannot see information from one subordinate region in another. The only VMDB with data visibility to all subordinate regions is the top level.

Master Regions Scope

  • Reports all information from all subordinate VMDBs reporting up to it.
  • Can perform power operations on virtual machines from subordinate regions.
  • Controls its own access control list.

Subordinate Regions Scope

  • Each subordinate controls its own access control independent of the other regions.
  • Can only do work (such as SmartState Analysis and Capacity and Utilization collection) in its own region.
  • Has no knowledge of the other regions.
  • Replicates its data up to the master region.

3.1.1.2. Region Settings

In the Region area, set items that apply to your entire CloudForms Management Engine infrastructure such as users, LDAP Groups, capacity and utilization collection, company tags and tag categories, and licensing. Regions are also used for database replication.

3.1.1.3. Capacity and Utilization Collections

3.1.1.3.1. Capacity and Utilization Collection Settings

Use C & U Collection Settings to select specifically which clusters and datastores you want to collect usage data for. By selecting a cluster, you are choosing to collect data for all hosts and virtual machines that are part of that cluster. You must also have a server with the Capacity & Utilization Coordinator, Data Collector, and Data Processor roles enabled as well. See Section Server Control Settings.

After a provider has been discovered and its relationships refreshed, the clusters, hosts, and datastores show under Configure → Configuration, then by clicking on the Settings → Region → C & U Collection tab.

3.1.1.3.2. Enabling a Cluster, Host, or Datastore for Capacity and Utilization Collection

To Enable a Cluster, Host, or Datastore for Capacity and Utilization Collection:

  1. Navigate to Configure → Configuration, then click on the Settings accordion.

  3. In the Clusters area, check all clusters and hosts that you want to collect data for.
  4. In the Datastores area, check all datastores that you want to collect data for.
  5. Click Save.
Note

As new clusters, hosts, and datastores are discovered, you will need to come back to this configuration to enable collection of capacity and utilization data unless you have used the Collect for All check boxes.

3.1.1.4. Tags

3.1.1.4.1. Company Tag Categories and Tags

CloudForms Management Engine allows you to create your own set of tags and tag categories. Use tags to create a customized, searchable index for your resources. Depending on your database type, your tags may be case sensitive. After creating these values, you can apply them to your resources. There are two kinds of tags.

  • Company tags which you will see under My Company Tags for a resource. Create company tags by navigating to Configure → Configuration, then clicking on the Settings, then selecting Region, then the My Company Tags tab. A selection of company tags is provided to you by default as samples. These can be deleted if you do not need them, but are not recreated by CloudForms Management Engine.
  • System tags are assigned automatically by CloudForms Management Engine.
Note

If you entered a Company Name under Configure → Configuration, then clicking on the Settings tab, then the Server your desired server, that name will appear on the tab instead of My Company.

3.1.1.4.2. Creating a Tag Category

  4. In the Category Information area, 2042

    • Use Name to create a short name that refers to category in the VMDB.

The Name and Single Value fields cannot be changed after the category has been added.

  • Use Display Name to specify how you want to see the name of the category in the Console.
  • Use Description to type a brief explanation of how the category should be used. This shows when you try to add a value to the category.
  • Check Show in Console when you feel that the category is ready for use in the console. For example, you want to populate values for the category before exposing it to users.
  • Check Single Value for categories that can only have a single value assigned to a resource. For example, a virtual machine can only be assigned to one location, but could belong to more than one department.

  • Check Capture C & U Data by tag to be able to group capacity and utilization data by this tag category. To use this, be sure to assign this tag to all the resources that you want to group by.

    1. Click Add.

Repeat these steps for each category you need. After you have created the category, you can add values to it.

Important

If no values are created for a category, you are unable to assign a value from that category nor be able to filter by that category.

The Red Hat Updates page enables you to edit customer information, register appliances, and update appliances. Editing customer information enables you to determine the registration point, User ID, and password. Red Hat CloudForms prompts you to update the Server URL when updating the registration point to a local Red Hat Satellite. The Status of Available Servers area provides options to refresh, register, check for updates, and to update. The Red Hat Updates page enables the Content Delivery Network (CDN) to assign the necessary update packages to the CloudForms Management Engine Server.

Using the Check For Updates task button, the CDN assigns any necessary update packages to your server and notifies you. Click Update and the CloudForms Management Engine packages install and update.

Three steps are required for updating the CloudForms Management Engine Appliance:

  1. Register the CloudForms Management Engine for updates if it is not already registered.
  2. Update the CloudForms Management Engine Appliance.
  3. Update other system packages.

The following tools are used during the update process:

  • Yum provides package installation, updates, and dependency checking.
  • Red Hat Subscription Manager manages subscriptions and entitlements.
  • Red Hat Satellite Server runs at customer locations providing local system registration and updates from inside the customer’s firewall.
Important

The update worker synchronizes the VMDB with the status of available CloudForms Management Engine content every 12 hours.

Note

Servers with the RHN Mirror role also act as a repository for other Appliances to pull CloudForms Management Engine packages updates.

3.1.1.7.1. Subscription Management for Virtual Environments

Customers can license Red Hat CloudForms for a limited set of providers. This ability is enabled by providing entitlement certificates that describe the features to be enabled. Red Hat CloudForms can be shipped as a bundled product with other Red Hat products like Red Hat Enterprise Linux OpenStack Platform and Red Hat OpenShift, providing advanced management capabilities to these products.

For more information on managing subscriptions for an IT infrastructure, see the Red Hat Subscription Management Subscription Concepts and Workflows guide.

Entitlements provides the following enhancements:

  • Ability to enable or disable providers based upon a certificate.
  • Active subscription with Red Hat Cloud Data Network for delivery to Red Hat CloudForms.
  • Ability to remain in its own Red Hat CloudForms channel.
  • Ability to add providers even if no certificate is found.
  • In the presence of a certificate, providers are limited as per SKU, the certificate is supporting.
  • Ability to support the provider to SKU mapping.
  • Providers remain fully functional even after adding or removing SKU associated with certificates.

You can organize your CloudForms Management Engine Infrastructure into zones to configure failover and isolate traffic. A provider that is discovered by a server in a specific zone gets monitored and managed in that zone. All jobs, such as a SmartState Analysis or VM power operation, dispatched by a server in a specific zone can get processed by any CloudForms Management Engine Appliance assigned to that same zone.

Zones can be created based on your own environment. You can make zones based on geographic location, network location, or function. When first started, a new server is put into the default zone.

Suppose you have four CloudForms Management Engine Appliances with two in the East zone, Appliances A and B, and two in the West zone, Appliances C and D. VC East is discovered by one of the CloudForms Management Engine Appliances in the CloudForms Management Engine Eastern zone. If Appliance A dispatches a job of analyzing twenty virtual machines, this job can be processed by either Appliance A or B, but not C or D.

3.1.4.1.3. Server Roles
Server RoleDescription

Automation Engine

Use this role if you want to use this CloudForms Management Engine server to process automation tasks.

Capacity and Utilization (three server roles)

  • The Capacity & Utilization Coordinator role checks to see if it is time to collect data, somewhat like a scheduler. If it is time, a job is queued for the Capacity and Utilization Data Collector. The coordinator role is required to complete Capacity and Utilization data collection. If more than one CloudForms Management Engine server in a specific zone has this role, only one will be active at a time.
  • The Capacity & Utilization Data Collector performs the actual collection of capacity and utilization data. This role has a dedicated worker, and there can be more than one CloudForms Management Engine server with this role in a zone.
  • The Capacity & Utilization Data Processor processes all of the data collected, allowing CloudForms Management Engine to create charts. This role has a dedicated worker, and there can be more than one CloudForms Management Engine server with this role in a zone.

Database Operations

Use Database Operations to enable this CloudForms Management Engine server to run database backups or garbage collection.

Database Synchronization

Use Database Synchronization to enable this CloudForms Management Engine server’s VMDB to replicate to a higher-level VMDB. This should only be enabled after creating settings for the Replication Worker.

Event Monitor

This role is enabled by default and provides the information shown in timelines. Event Monitor is responsible for the work between the CloudForms Management Engine server and your providers. It starts 2 workers for each provider. One worker, the monitor, is responsible for maintaining a connection to a provider, catching events, and putting them on the CloudForms Management Engine message queue for processing. The second worker, the handler, is a message queue worker responsible for delivering only those messages for a provider. You should have at least one of these in each zone.

Notifier

Use this role if you will be using CloudForms Management Engine Control or Automate to forward SNMP traps to a monitoring system or send e-mails. See Section 3.1.4.1.6, “Configuring SNMP” for details on creating SNMP alerts. If more than one CloudForms Management Engine server in a specific zone has this role, only one will be active at a time.

Provider Inventory

This role is enabled by default. This role is responsible for refreshing provider information including EMS, hosts, virtual machines, and clusters, and is also responsible for capturing datastore file lists. If more than one CloudForms Management Engine server in a specific zone has this role, only one will be active at a time.

Provider Operations

This role is enabled by default. This role sends stop, start, suspend, shutdown guest, clone, reconfigure, and unregister to the provider, directly from the console or through a policy action if you have CloudForms Management Engine Control. More than one CloudForms Management Engine server can have this role in a zone.

RHN Mirror

An appliance with RHN Mirror enabled acts as a server containing a repository with the latest CloudForms Management Engine packages. This also configures other Appliances within the same region to point to the chosen RHN Mirror server for updates. This provides a low bandwidth method to update environments with multiple Appliances.

Reporting

This role is enabled by default. The Reporting role specifies which CloudForms Management Engine servers can generate reports. If you do not have a CloudForms Management Engine server set to this role in a zone, then no reports can be generated in that zone. You should have at least one of these in each zone.

Scheduler

This role is enabled by default. The Scheduler sends messages to start all scheduled activities such as report generation and SmartState Analysis. This role also controls all system schedules such as capacity and utilization data gathering. One server in each zone must be assigned this role or scheduled CloudForms Management Engine events will not occur. If more than one CloudForms Management Engine server in a specific zone has this role, only one will be active at a time.

SmartProxy

Enabling the SmartProxy role turns on the embedded SmartProxy on the CloudForms Management Engine server. The embedded SmartProxy can analyze virtual machines that are registered to a Host and templates that are associated with a provider. To provide visibility to repositories, install the SmartProxy on a host from the CloudForms Management Engine console. This SmartProxy can also analyze virtual machines on the host on which it is installed.

SmartState Analysis

This role is enabled by default. The SmartState Analysis role controls which CloudForms Management Engine servers can control SmartState Analyses and process the data from the analysis. You should have at least one of these in each zone.

User Interface

This role is enabled by default. Uncheck User Interface if you do not want users to be able to access this CloudForms Management Engine server using the CloudForms Management Engine console. For example, you may want to turn this off if the CloudForms Management Engine server is strictly being used for capacity and utilization or reporting generation. More than one CloudForms Management Engine server can have this role in a zone.

Web Services

This role is enabled by default. Uncheck Web Services to stop this CloudForms Management Engine server from acting as a Web service provider. More than one CloudForms Management Engine server can have this role in a zone.

3.1.4.1.4. VMware Console Settings

If you are using the CloudForms Management Engine Control feature set, then you have the ability to connect to a Web console for virtual machines that are registered to a host. To use this feature, you must have VNC installed, the appropriate version of the VMware MKS plug-in or the appropriate VMRC viewer installed in your Web browser.

Note
  • You are responsible for installing the correct version for your virtual infrastructure. See vendors documentation for information. After installing the appropriate software or version, you must specify which version you are using in the CloudForms Management Engine configuration settings.
  • To edit the VMware MKS plug-in settings, you must have the super administrator role.

2061

  • If you select VNC, type in the port number used. This port must be open on the target virtual machine and the VNC software must be installed there. On the computer that you are running the console from, you must install the appropriate version of Java Runtime if it is not already installed.
  • If you select VMware MKS plug-in, select the appropriate version.
  • If using VMware VMRC plug-in, be sure that you have fulfilled the requirements. The correct version of the VMRC plug-in from VMware must be installed on the client computer. To do this, log into the Virtual Center Web Service and attempt to open a virtual machine console. This should prompt you to install the required plug-in. The VSphere Web Client must be installed on VC version 5, and the provider must be registered to it. For Virtual Center version 4, the VMware VirtualCenter Management Webservice must be running.

3.1.4.2.2. Authentication Settings

2067

  • Use Session Timeout to set the period of inactivity before a user is logged out of the console.
  • Use Mode to set the type of authentication. Choose from Database (using the VMDB), LDAP (Lightweight Directory Authentication Protocol), LDAPS (Secure Lightweight Directory Authentication Protocol), or Amazon. The default is Database. If you choose Database, see Section Creating a User to create users. See section LDAP Settings for more information on configuration for LDAP and LDAPS. If you choose Amazon, see section Amazon Settings.
3.1.4.2.3. LDAP Settings

If you choose LDAP or LDAPS as your authentication mode, required parameters are exposed under LDAP Settings. Be sure to validate your setting before saving them.

2068

  • Use LDAP Host Name to specify the fully qualified domain names of your LDAP servers. CloudForms Management Engine will search each host name in order until it finds one that authenticates the user.
  • Use LDAP Port to specify the port for your LDAP server. The default is 389 for LDAP and 636 for LDAPS.
  • From the User Type list, select User Principal Name to type the user name in the format of user@domainname. Select Email Address to login with the users email address. Select Distinguished Name (CN=<user>) or Distinguished Name (UID=<user>) to use just the user name, but be sure to enter the proper User Suffix for either one. Choose the correct Distinguished Name option for your directory service implementation.
  • Specify the User Suffix, such as acme.com for User Principal Name or cn=users,dc=acme,dc=com for Distinguished Name, in Base DN.
3.1.4.2.4. LDAP Role Settings

If you choose LDAP, you can use groups from your directory service to set the role for the authenticated LDAP User. The LDAP user must be in one of the Account Role Groups. See Section “LDAP Groups”.

If you do not check Get User Groups from LDAP, the user must be defined in the VMDB using the console where the User ID is the same as the user’s name in your directory service typed in lowercase. For example, dbright@acme.com when using User Principal Name, cn=dan bright,ou=users,dc=acme,dc=com when using Distinguished Name (CN=<user>), or uid=dan bright,ou=users,dc=acme,dc=com when using Distinguished Name (UID=<user>). Then, when logging in, the user would type either dbright (User Principal Name) or dan bright (Distinguished Name). If the user is not defined in the VMDB, they will be denied access to CloudForms Management Engine.

2069

  • Check Get Roles from Home Forest to use the LDAP roles from the LDAP users home forest.
  • Check Follow Referrals to lookup and bind a user that exists in a domain other than the one configured in the LDAP authentication settings.
  • Use Base DN to set the place in the directory tree from which you want to start searching for users.
  • Specify the user name to bind to the LDAP server in Bind DN. This user must have read access to all users and groups that will be used for CloudForms Management Engine authentication and role assignment.
  • Specify the password for the Bind DN user in Bind Password.

Click Validate to verify your settings.

3.1.4.2.5. Amazon Settings

If you choose Amazon as your authentication mode, required parameters are exposed under Amazon Primary AWS Account Settings for IAM. Be sure to validate your setting before saving them.

  • Type in an Access Key provided by your Amazon account.
  • Type in a Secret Key provided by your Amazon account.

Users logging into CloudForms Management Engine with Amazon authentication enter their own IAM Access Key as the username and IAM Secret Key as the password. Amazon users must be added as a CloudForms Management Engine user or belong to an IAM user group added to the list of CloudForms Management Engine groups.

3.1.4.2.6. Trusted Forests

If a user has group memberships in another LDAP Forest, then specify the settings to access the memberships in the trusted forest.

When trusted forests are added to the authentication configuration, they are used only for finding groups that a user is a member of. CloudForms Management Engine will first collect all of the user’s groups from the primary LDAP directory. Then it will collect any additional groups that the user is a member of from all of the configured forests.

The collected LDAP groups are used to match, by name, against the groups defined in CloudForms Management Engine. The user must be a member of at least one matching LDAP group to be successfully authenticated.

3.1.4.2.7. Adding Settings for a Trusted Forest

To Add Settings for a Trusted Forest:

  1. Navigate to Configure → Configuration.
  2. Click on the Settings accordion, then click Zones.

3.1.4.2.8. External Authentication (httpd)

When external authentication is enabled, users can log in to the CloudForms Management Engine appliance using their IPA server credentials. The appliance creates user accounts automatically and imports relevant information from the IPA Server.

The appliance contains IPA client software for connecting to IPA servers, but it is not configured by default. External authentication is enabled by first configuring it in the web interface, then in the console. Disabling external authentication and returning to internal database authentication also requires steps in both the web interface and the console.

Requirements

  • For an appliance to leverage an IPA Server on the network, both the appliance and the IPA server must have their clocks synchronized or Kerberos and LDAP authentication fail.
  • The IPA Server must be known by DNS and accessible by name. If DNS is not configured accordingly, the hosts files need to be updated to reflect both IPA server and the appliance on both virtual machines.
  • For users to log in to the appliance using IPA server credentials, they must be members of at least one group on the IPA server which is also defined in the appliance. Navigate to Configure → Configuration → Access Control → Groups to administer groups.

Configuring Appliance for External Authentication

To configure the appliance for external authentication, first set up authentication using the web interface, then using the console.

Using the Web Interface:

  1. Log in to the web interface as an administrative user.
  2. Navigate to Configure → Configuration → Zone → Server → NTP Servers or use the hosting provider of the virtual machine to synchronize the appliance’s time with an NTP server.
  3. Navigate to Configure → Configuration → Authentication.
  4. Select a Session Timeout if required.
  5. Select External (httpd) in the Mode list.
  6. Select Enable Single Sign-On to allow single sign-on using Kerberos tickets from client machines that authenticate to the same IPA server as the appliance.

  8. Click Save.

Using the Console:

  1. Log in to the appliance console using the user name admin.

  2. The summary screen displays: 

    External Auth:  not configured
  3. Press Enter.
  4. Enter 10 to select Configure External Authentication (httpd).
  5. Enter the fully qualified hostname of the IPA Server, for example ipaserver.test.company.com.
  6. Enter the IPA server domain, for example test.company.com.
  7. Enter the IPA server realm, for example TEST.COMPANY.COM.
  8. Enter the IPA server principal, for example admin.
  9. Enter the password of the IPA server principal.
  10. Enter y to proceed.
Note

If any of the following conditions are true, configuration fails:

  • The IPA server is not reachable by its FQDN
  • The IPA server cannot reach the appliance by its FQDN
  • The time is not synchronized between the appliance and the IPA server
  • The IPA server admin password is entered incorrectly

Reverting to Internal Database Authentication

To revert to internal database authentication, first configure authentication using the web interface, then using the console.

Using the Web Interface:

  1. Log in to the web interface as an administrative user.
  2. Navigate to Configure → Configuration → Authentication.
  3. Select Database in the Mode list.
  4. Click Save.

Using the Console:

  1. Log in to the appliance console using the user name admin.

  2. The summary screen displays: 

    External Auth:  IPA.server.FQDN

    Press Enter.

  3. Enter 10 to select Configure External Authentication (httpd). The currently configured IPA server hostname and domain are displayed.
  4. Enter y to un-configure the IPA client.

Optional Configuration Using the Appliance Console CLI

In addition to using the appliance console, external authentication can optionally be configured and un-configured using the appliance console command line interface.

Appliance console CLI command and relevant options include: 

/bin/appliance_console_cli --host <appliance_fqdn>
                           --ipaserver <ipa_server_fqdn>
                           --iparealm <realm_of_ipa_server>
                           --ipaprincipal <ipa_server_principal>
                           --ipapassword <ipa_server_password>
                           --uninstall-ipa
--host:

updates the hostname of the appliance. If you performed this step using the console and made the necessary updates made to /etc/hosts if DNS is not properly configured, you can omit the --host option. 

--iparealm:

if omitted, the iparealm is based on the domain name of the ipaserver. 

--ipaprincipal:

if omitted, defaults to admin.

Example 3.1. Configuring External Authentication

$ ssh root@appliance.test.company.com
[appliance]# /bin/appliance_console_cli --host appliance.test.company.com \
                                      --ipaserver ipaserver.test.company.com \
                                      --iparealm TEST.COMPANY.COM \
                                      --ipaprincipal admin \
                                      --ipapassword smartvm1

Specify if you want the coresident SmartProxy to use a shared connection through the VIM broker to communicate with the VC or ESX host for SmartState Analysis. If it is disabled, then each SmartProxy SmartState Analysis would create its own connection. Default: true

concurrent_per_ems

Specify the number of co-resident SmartProxy SmartState Analyses that can be run against a specific management system at the same time. Default: 1

concurrent_per_host

Specify the number of co-resident SmartProxy SmartState Analyses that can be run against a specific host at the same time. Default: 1

scan_via_host

If you change scan_via_host to false, CFME will use the Management System to scan which is limited by the concurrent_per_ems setting instead of the concurrent_per_host setting. Note this will greatly increase traffic to the Management System. Default: true

Table: ems_refresh

ParametersDescription

capture_vm_created_on_date

Set to false to turn off historical event retrieval. Set to true to turn on. By setting the flag to true CFME will try to set the "ems_created_on" column in the vms table after an ems refresh for new VMs and any VMs with a nil "ems_created_on" value. CFME looks at event information in our database as well as looking up historical event data from the management system. This is optional since the historical lookup could timeout. Default: false

collect_advanced_settings

Set to false if you do not want to collect advanced Virtual Machine settings during a management system refresh. This will increase the speed of the refresh, but less data will be collected. If the parameter is not listed, then the value is true. Default: true

ec2

 

get_private_images

For EC2 refreshes only; whether or not to retrieve private images. Default: true

get_public_images

For EC2 refreshes only; whether or not to retrieve public images. Default: false. Warning: setting get_public_images to true loads several thousand images in the VMDB by default and may cause performance issues.

For EC2 refreshes only; whether or not to ignore terminated instances. Default: true

full_refresh_threshold

The number of targeted refreshes requested before they are rolled into a full refresh. For example, if the system and/or the user target a refresh against 7 VMs and 2 Hosts (9 targets), when the refresh actually occurs it will do a partial refresh against those 9 targets only. However, if a 10th had been added, the system would perform a full EMS refresh instead. Default: 100

raise_vm_snapshot_complete_if_created_within:

Raises vm_snapshot_complete event for a snapshot being added to VMDB only if the create time in Virtual Center is within the configured period of time. This prevents raising events for old snapshots when a new VC is added to CFME. Default: 15.minutes

  5. Under Product Features (Editing), navigate to the appropriate feature and enable or disable it. 2096
  6. Click Add.

3.3. Diagnostics

From navigating to Configure → Configuration, then clicking on the Diagnostics tab, you can also see the status of the different CloudForms Management Engine roles and workers for each server, view and collect logs, and gather data if there are any gaps in capacity and utilization information. The Diagnostics area is designed in a hierarchy.

  • At the region level, you can see replication status, backup the VMDB, and run garbage collection on the VMDB.
  • At the zone level, you can see CloudForms Management Engine roles by servers and servers by roles. In addition, you can set log collection values for a specific zone, and collect gap data for capacity and utilization.
  • At the server level, you can see the workers for each server, set log collection values for a specific server, and view current logs.

3.3.1. Region Diagnostics

Using the console, you can set the priority of server regional roles, review and reset replication, and create backups of your database either on demand or on a schedule.

Regions are used primarily to consolidate multiple VMDBs into one master VMDB for reporting while zones are used to define functional groups of servers. There can be only one region per VMDB, but multiple zones per region (or VMDB). Some server roles are aware of each other across CloudForms Management Engine Appliances at the region level. This means that redundancy and failover rules apply at the region level. You can also set priorities for the server roles that provide failover.

If you have multiple servers in your environment with duplicate failover roles, then you can set the priority of the server role.

  • Only server roles that support failover can be marked as primary. These roles only allow one server to be active at a time. These are Notifier, Capacity & Utilization Coordinator, Database Synchronization, Event Monitor, Scheduler, Storage Inventory, and Provider Inventory.
  • All other server roles are additive. The more servers with that role in a zone the more work that can be performed.

There are three role priorities.

  • Primary: There can only be one primary per zone or region per role. When an appliance is started, the system looks to see if any role is set to primary. If that is the case, the role is activated on that appliance and deactivated from the secondary. In the console, primary roles are shown in bold letters. The text turns red if the server goes down. You must actively set the primary priority.
  • Secondary: This is the default priority. There can be multiple secondaries. When an appliance is started, if no primary is found in the zone, the first appliance to start takes the role. In the console, secondary roles are displayed normally with the word "secondary".
  • Tertiary: If all appliances with primary roles or secondary roles were down, one of the tertiary would be activated. The reason for tertiary is to ensure that if a server with crucial roles such as Provider Inventory or Event Monitor goes down, you have a way to associate those roles to different appliances by organizing the priorities. Tertiary roles simply show as active in the console.

  6. Click 1847 (Configuration), and 2098 (Demote Server) to demote the priority of this server for this role.

3.3.4. Replication

You must be on the server where replication has been set up to monitor status. To run backups, the database operations server role must be enabled. Databases can then be restored using the black console on the CloudForms Management Engine Appliance. These features are available only when using the internal PostgreSQL VMDB.

3.3.4.1. Monitoring Database Replication

To Monitor Database Replication:

  1. Navigate to Configure → Configuration.
  2. Click the Diagnostics accordion and click the Region being replicated.
  3. Click the Replication tab to view the status of the replication process and the backlog of database records queued for replication.

If directed to by Red Hat, you may need to reset replication. Do this from the server that is replicating up to a higher level VMDB. When you do this, the subordinate regions data is removed from the top level, and then the replication is restarted.

3.3.4.2. Resetting Replication

To Reset Replication:

  1. Navigate to Configure → Configuration.
  2. Click on the Diagnostics accordion, then click Region name.
  3. Click the Replication tab.

3.3.4.3. Running a Single Backup

To Run a Single Backup:

  1. Navigate to Configure → Configuration.
  2. Click on the Diagnostics accordion, then click Region name.
  3. Click the Database tab.
  4. If you have created a backup schedule, and want to use the same depot settings, select it under Backup Schedules.
  5. If you do not want to use the settings from a backup schedule, or need to create settings, go into the Database Backup Settings area.

  6. Select a type of server to put the backups. You can either use Network File System or Samba. 2099

    • If selecting Samba, enter the Depot Name, URI, User ID, a Password, and a valid Password. Click Validate to check the settings.
    • If you choose Network File System, enter the Depot Name and URI.
  7. Click Submit.

The database backup is run immediately. You can see the task by navigating to Configure → Tasks, then clicking on the All Other Tasks tab.

3.3.4.4. Restoring a Database from Backup

To Restore a Database from Backup:

  1. Copy the database backup file to /tmp, and name it evm_db.backup. The server looks specifically for this file to restore from.
  2. Log in to the black appliance console with a user name of admin and the default password. The CloudForms Management Engine Appliance summary screen displays.
  3. Press Enter to manually configure settings.
  4. Press the number 6 to select Restore Database From Backup.
  5. Press Y to confirm.

If directed by Red Hat, you can run database garbage collection to reclaim unused space in your VMDB. Generally, the database server does this automatically.

3.3.5. Zone Diagnostics

The console provides a way to see all the server roles that a server has been assigned and if these roles are running. This is especially helpful when you have multiple servers with different server roles. For each zone you can also set a central place for all logs to be collected, and collect capacity and utilization data that may be missing.

3.3.5.1. Viewing the Status of Server Roles

To View the Status of Server Roles:

  1. Navigate to Configure → Configuration.
  2. Click on the Diagnostics accordion, then click the Zone that you want to view.
  3. Depending on how you want to view your servers, click either Roles by Servers or the Servers by Roles.

3.3.5.2. Setting Server Role Priorities

If you have multiple servers in your environment with duplicate failover roles, then you can set the priority of the server role.

  • Only server roles that support failover can be marked as primary. These are Notifier, Capacity & Utilization Coordinator, Database Synchronization, Event Monitor, Scheduler, Storage Inventory, and Provider Inventory.
  • All other server roles are additive. The more servers with that role in a zone the more work that can be performed.

There are three role priorities.

  • Primary: There can only be one primary per zone per role. When an appliance is started, the system looks to see if any role is set to primary. If that is the case, the role is activated on that appliance and deactivated from the secondary. In the console, primary roles are shown in bold letters. The text turns red if the server goes down.
  • Secondary: This is the default priority. There can be multiple secondaries. When an appliance is started, if no primary is found in the zone, the first appliance to start takes the role. In the console, secondary roles are displayed normally with the word "secondary".
  • Tertiary: If all appliances with primary roles or secondary roles are down, one of the tertiary would be activated. The reason for tertiary is to ensure that if a Server with crucial roles such as Provider Inventory or Event Monitor goes down, you have a way to associate those roles to different appliances by organizing the priorities. Tertiary roles simply show as active in the console.

3.4.2. Database Regions and Replication

3.4.2.1. Database Regions and Replication

Regions are used to create a central database for reporting and charting. Do not use the database at the top level for operational tasks such as SmartState Analysis or Capacity and Utilization data collection. Assign each server participating in the region a unique number during the regionalization process, then set your subordinate regions to replicate to the top region.

Note

Only enable database synchronization on subordinate servers with replication worker settings already configured. Do not enable more than one Database Synchronization role per region.

For diagnostic information on replication, see Section "Monitoring Database Replication”.

The following is an example of regionalized database scenario:

  1. Create Region Number 99 to which all other VMDBs replicate.

    • Treat this as a read only database for reporting and charting.
    • Enable only the Reporting, Scheduler, and User Interface Server Roles. To perform database maintenance items, such as scheduled backups, on the top-level region (master), also enable the Database Operations role.
    • No additional settings aside from assigning the region ID. No need to configure any replication.

  2. Create Region Number 1

    1. Add replication worker settings pointing to the VMDB for Region 99.
    2. Enable Database Synchronization Server role on one Server in the Region. If you have a second Server in the same region, do not enable the DB Synchronization role. Do not enable more than one Database Synchronization Role per Region.

  3. Create Region Number 2

    1. Add replication worker settings pointing to the VMDB for Region 99.
    2. Enable Database Synchronization Server role on one Server in the Region. If you have a second +Server in the same region, do not enable the DB Synchronization role. Do not enable more than one Database Synchronization Role per Region.
Important

All CFME databases in a multi-region deployment must use the same security key.

3.4.2.2. Creating a Region

In most cases, a region is created when you are deploying your CFME environment; essentially, on the first Appliance for the region. The process of creating a region takes a few minutes. The database is dropped and rebuilt to accommodate the region numbers.

Note

To configure a database for CFME, follow the procedure described here.

To create a region:

  1. Start the appliance and log in to the black appliance console with a user name of admin and the default password. The Appliance Summary Screen displays.
  2. Press Enter to manually configure settings.
  3. Enter 12 to Stop EVM Server Processes.
  4. Enter Y to confirm.
  5. The menu reappears after all processes are complete.

  6. Choose Configure Database.

    Warning

    Performing this action destroys any existing data and cannot be undone. Back up the existing database before proceeding. By default, new CloudForms Management Engine Appliances are assigned region 0. Do not use this number when creating a region as duplicating region numbers can compromise the integrity of the data.

  7. Enter a database region number that has not been used in your environment. Do not enter duplicate region numbers as this can corrupt the data.
  8. Enter Y to confirm.
  9. The menu reappears after all processes are complete.
  10. Enter 13 to Start EVM Server Processes.
  11. Enter Y to confirm.

After a region is created, you can create subordinate regions as necessary and set up replication to the top level region.

    4. Password and Verify Password: the password for the user name.
    5. Host: the IP address or hostname of the top level VMDB.
  6. Click Validate to confirm that the VMDB is accessible.
  7. Click Save.

3.4.4. Enabling the Database Synchronization Role

When you start the replication worker, all of the information in the subordinate database is sent to the top region (99). The worker also creates triggers so that future changes made to subordinate regions are sent automatically to the top region.

To Enable the Database Synchronization Role:

  1. Navigate to Configure → Configuration.
  2. Click the Settings accordion and click Zones.

  3. Click the Zone where the server is located and click the server name.

To change the password, you need to stop the CloudForms Management Engine Service, change the password for the PostgreSQL database, run a command to change the password in the configuration file that emserverd uses to access the server, and restart the CloudForms Management Engine Appliance.

  1. Stop the CloudForms Management Engine Service.

    • SSH into the appliance.

    • To stop the CloudForms Management Engine service, run the following command: 

      service evmserverd stop

  2. Use pgadmin to change the password for your CloudForms Management Engine database (default is vmdb_production). If you do not have pgadmin, then you can change the password by running: 

    psql -U root -d vmdb_production

    • At the vmdb# prompt, type: 

      ALTER USER root WITH PASSWORD 'newpassword';

    • To exit psql, type: 

      \q

  3. Run the following command to change the password in the configuration file that emserverd uses to access the server: 

    /var/www/miq/vmdb/tools/fix_auth.rb --databaseyml --password newpassword

  4. To restart the CloudForms Management Engine service, run the following command: 

    service evmserverd start
  5. Verify that you can log in to the CloudForms Management Engine Console.

3.4.5.2. Changing the Password on the Worker Appliances

  1. Stop the CloudForms Management Engine Service.

    /var/www/miq/vmdb/tools/fix_auth.rb --databaseyml --password newpassword

  3. To restart the CloudForms Management Engine service, run the following command: 

    service evmserverd start
    Important

    Requisites for Replication

    If you are using replication, and you have changed the password on the Master database, you will also need to update the password used for the Replication Worker on the subordinate regions.

    • Disable the Database Synchronization Role.
    • Update the Replication Worker's password.
    • Restart the Database Synchronization Role.

3.4.5.3. Adding a New Appliance to an Existing Region with Non-default Password

  1. Create the new appliance.
  2. Start it, but do not go into any of the configuration options, instead SSH into the new appliance.
  3. In the /var/www/miq/vmdb directory create a file called REGION. Its only contents should be the number of the Region that it is joining. (You could also just copy the REGION file from the VMDB Appliance.)

  4. Edit the database.yml file in the /var/www/miq/vmdb directory. (You may want to save off the original.)

    • Replace the contents of the "production" section with the contents of the "base" section.
    • Edit the "host" parameter to match IP of the appliance hosting the VMDB.
    • Save the new database.yml.

    • Run the following command to change the password in the configuration file that emserverd uses to access the server: 

      /var/www/miq/vmdb/tools/fix_auth.rb --databaseyml --password newpassword
  5. Restart the new worker appliance by typing: 
service evmserverd restart
