Chapter 7. Monitoring
ACK AUT OACK — Does not change the destination of the notification, but automatically
acknowledges matching alerts as soon as they are sent.
ACK REDIR — Sends the notification to the redirect destination(s) instead of the default destination.
T he format of the rule should be filter_type probe_type duration email_address where
filter_type indicates one of the previous advanced commands, probe_type indicates probe or
system, duration indicates the length of time for the redirect, and email_address indicates the
intended recipient. For example:
ACK METOO system 1h [email protected]
Capitalization is not required. Duration can be listed in minutes (m), hours (h), or days (d). Email
addresses are needed only for redirects (REDIR) and supplemental (MET OO) notifications.
T he description of the action contained in the resulting email defaults to the command entered by the
user. T he reason listed is a summary of the action, such as em ail ack redirect by
user@ dom ain.com where user equals the sender of the email.
Note
You can halt or redirect almost all probe notifications by replying to a notification emails with a
variation of the command ack suspend host. However, you cannot halt Satellite probe
notifications by responding to a probe with ack suspend host or other redirect responses.
T hese probes require you to change the notifications within the web interface of the Satellite.
7.4.4. Filtering Notifications
Since notifications can be generated whenever a probe changes state, simple changes in your network
can result in a flood of notifications. T he creation, cancellation, and application of Notification filters is
discussed in detail in Section 6.10.2.1, “Notification ⇒ Filters”.
7.4.5. Deleting Notification Methods
T heoretically, removing notification methods should be as easy as creating them. After all, you must
populate no fields to conduct the deletion and a button exists for this explicit purpose. However, existing
relationships between methods and probes can complicate this process. Follow these steps to remove a
notification method:
1. Log into the RHN website as an Satellite Administrator or Monitoring Administrator.
2. Navigate to the Monitoring ⇒ Notifications page and click the name of the method to be
removed.
3. On the User Details ⇒ Notification Methods tab, click delete m ethod. If the method
is not associated with any probes, you are presented with a confirmation page. Click Confirm
Deletion. T he notification method is removed.
Tip
Since both the notification method name and address can be edited, consider updating the
method rather than deleting it. T his redirects notifications from all probes using the method
without having to edit each probe and create a new notification method.
