Chapter 7. Monitoring
7.4.1. 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 Organization Administrator or Monitoring
Administrator.
2. Navigate to the
User Details
⇒
Notification Methods
tab and click
create new
method
.
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 notifi-
cation 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 no-
tification method from the resulting pulldown menu. Notification methods assigned
to probes cannot be deleted until they are dis-associated from the probe.
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" ([email protected])
Date: Mon, 6 Dec 2004 13:42:28 -0800
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)
