Receiving Notifications; Redirecting Notifications - Red Hat NETWORK 3.7 Reference Manual

Chapter 7. Monitoring
6. While adding probes, select the Probe Notifications checkbox and select the new notification
method from the resulting pulldown menu. Understand that notification methods assigned to
probes cannot be deleted until that association has been removed.
7.3.2. Receiving Notifications
If you create notification methods and associate them with probes, you must be prepared to receive
them. These notifications will 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
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
7.3.3. Redirecting Notifications
Upon receiving a notification, you may redirect it by including advanced notification rules within an
acknowledgement email. Just reply to the notification and include the desired option. These are the
possible redirect options, or filter types:
ACK METOO — Sends the notification to the redirect destination(s) in addition to the default
•
destination.
ACK SUSPEND — Sends the notification to nobody instead of the default destination.
•
ACK AUTOACK — Does not change the destination of the notification, but automatically acknowl-
•
edges matching alerts as soon as they are sent to prevent escalations.
ACK REDIR — Sends the notification to the redirect destination(s) instead of the default destina-
•
tion.
The format of the rule should be filter_type probe_type duration email_address
where filter type equals one of the following advanced commands, probe type equals probe or system,
duration equals the length of time for the redirect, and email address equals the intended recipient.
