7.4.2. 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. 

Time: Mon Dec 06, 21:42:25 PST 
State: CRITICAL
System: [hostname] ([IP address]) 
Probe: Satellite: Users 
Message: Users 6 (above critical threshold of 2)
Notification #116 for Users
 
Run from: RHN Monitoring Satellite

As you can see, the longer email notifications contain virtually everything you would need to know about the associated probe. In addition to the probe command, run time, system monitored, and state, the message contains the Send ID, which is a unique character string representing the precise message and probe. In the above message, the Send ID is 01dc8hqw.
Pager notifications, by necessity, contain only the most important details, namely the subject of the email message (containing state, system, probe, and time) and the Send ID. Here is an example pager notification: 
 CRITICAL: [hostname]: Satellite: Users at 21:42 PST, notification 01dc8hqw
