Once finished, your Satellite may be used to schedule MySQL probes.

8.4. Notifications

In addition to viewing probe status within the RHN 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 RHN, you must have identified a mail exchange server and mail
domain during installation of your RHN Satellite and configured sendmail to properly handle incoming
mail. Refer to the Installation chapter of the RHN Satellite Installation Guide for details.

8.4.1. Creating Notification Methods

Notifications are sent via a notification method, an email or pager address associated with a
specific RHN 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 RHN website as either an Satellite Administrator or Monitoring Administrator.
2. Navigate to the User Details
3. Enter an intuitive, descriptive label for the method name, such as DBA day email, and provide
the correct email or pager 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 pager. 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.

8.4.2. Receiving Notifications

If you create notification methods and associate them with probes, you must be prepared to receive
them. These notifications come in the form of brief text messages sent to either email or pager
addresses. Here is an example of an email notification:
Subject: CRITICAL: [hostname]: Satellite: Users at 1
From: "Monitoring Satellite Notification" (rogerthat01@redhat.com)
Date: Mon, 6 Dec 2004 13:42:28 -0800
To: user@organization.com
This is RHN Monitoring Satellite notification 01dc8hqw.
Notification Methods tab and click create new method.
