1.2.4. Enabling Notifications

In addition to viewing probe status within the Red Hat Network interface, you may be notified whenever a probe changes state. This is especially important when monitoring mission-critical production systems. For this reason, Red Hat recommends taking advantage of this feature.
To enable probe notifications within Red Hat Network, you must have identified a mail exchange server and mail domain during installation of your Red Hat Satellite and configured sendmail to properly handle incoming mail. See the Installation section of the Red Hat Satellite Installation Guide for details.

1.2.4.1. Creating Notification Methods

Notifications are sent via a notification method, an email or pager address associated with a specific Red Hat Network user. Although the address is tied to a particular user account, it may serve multiple administrators through an alias or mailing list. Each user account can contain multiple notification methods. To create a notification method:
  1. Log into the Satellite as either a Satellite Administrator or Monitoring Administrator.
  2. Navigate to Users and select the username. On the User Details page, click on Notification Methods → create new method.
  3. Enter an intuitive, descriptive label for the method name, such as DBA day email, and provide the correct email address. Remember, the labels for all notification methods are available in a single list during probe creation, so they should be unique to your organization.
  4. Select the checkbox if you desire abbreviated messages to be sent to the email address. This shorter format contains only the probe state, system hostname, probe name, time of message, and Send ID. The standard, longer format displays additional message headers, system and probe details, and instructions for response.
  5. When finished, click Create Method. The new method shows up in the User Details → Notification Methods tab and the Notification page under the top Monitoring category. Click its name to edit or delete it.
  6. While adding probes, select the Probe Notifications checkbox and select the new notification method from the resulting dropdown menu. Notification methods assigned to probes cannot be deleted until they are dis-associated from the probe.
