Chapter 3. Install the Client-Side Tools

Before you deploy the overcloud, you need to determine the configuration settings to apply to each client. Copy the example environment files from the director’s Heat template collection and modify them to suit your environment.

3.1. Set Centralized Logging Client Parameters

For Fluentd configuration settings, copy /usr/share/openstack-tripleo-heat-templates/environments/logging-environment.yaml and modify the file to suit your environment. For example:

Simple configuration

resource_registry:
  OS::TripleO::Services::FluentdClient: ../puppet/services/logging/fluentd-client.yaml

parameter_defaults:
  LoggingServers:
    - host: log0.example.com
      port: 24224
    - host: log1.example.com
      port: 24224

Example SSL configuration

## (note the use of port 24284 for ssl connections)

resource_registry:
  OS::TripleO::Services::FluentdClient: ../puppet/services/logging/fluentd-client.yaml

parameter_defaults:
  LoggingServers:
    - host: 192.0.2.11
      port: 24284
  LoggingUsesSSL: true
  LoggingSharedKey: secret
  LoggingSSLCertificate: |
    -----BEGIN CERTIFICATE-----
    ...certificate data here...
    -----END CERTIFICATE-----

  • LoggingServers - The destination system that will receive Fluentd log messages.
  • LoggingUsesSSL - Setting that determines whether secure_forward is used when forwarding log messages.
  • LoggingSharedKey - The shared secret used by secure_forward.
  • LoggingSSLCertificate - The PEM-encoded contents of the SSL CA certificate.

3.2. Set Availability Monitoring Client Parameters

For the Sensu client configuration settings, copy /usr/share/openstack-tripleo-heat-templates/environments/monitoring-environment.yaml and modify the file to suit your environment. For example: 

resource_registry:
  OS::TripleO::Services::SensuClient: ../puppet/services/monitoring/sensu-client.yaml

parameter_defaults:
  MonitoringRabbitHost: 10.10.10.10
  MonitoringRabbitPort: 5672
  MonitoringRabbitUserName: sensu
  MonitoringRabbitPassword: sensu
  MonitoringRabbitUseSSL: false
  MonitoringRabbitVhost: "/sensu"
  SensuClientCustomConfig:
    api:
      warning: 10
      critical: 20
  • MonitoringRabbit - These parameters connect the Sensu client services to the RabbitMQ instance that runs on the monitoring server.
  • MonitoringRabbitUseSSL - This parameter is not currently available for availability monitoring.
  • SensuClientCustomConfig - Specify additional Sensu client configuration. Defines the OpenStack credentials to be used, including username/password, auth_url, tenant, and region.

3.3. Install Operational Tools on Overcloud Nodes

Include the modified YAML files with your openstack overcloud deploy command to install the Sensu client and Fluentd tools on all overcloud nodes. For example: 

$ openstack overcloud deploy --templates  -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e network-environment.yaml -e ~/templates/monitoring-environment.yaml -e ~/templates/logging-environment.yaml --control-scale 3 --compute-scale 1 --ntp-server 192.168.122.10
