Emailaddresses are needed only for redirects (REDIR) and supplemental (METOO) notifications.The description of the action contained in the resulting email will default to the precise commandentered by the user. The reason listed will be a summary of the action, such as email ack redirectby user@domain.com where user equals the sender of the email.7.3.4. Filtering NotificationsSince notifications can be generated whenever a probe changes state, simple changes in your networkcan result in a flood of notifications. Although Red Hat recommends installing your own mail filtersto appropriately route and flag these messages, we also recognize the need to outright halt them.To this end, Red Hat Network offers the Silence All Notifications mechanism. This checkbox can befound within the Monitoring category of the RHN website, within the General Config page.To temporarily filter, or suspend, all notifications generated by your Monitoring infrastructure, selectthe Silence All Notifications checkbox, and click Update Config. To restore notifications, uncheckthe box and once again update your configuration.7.3.5. Deleting Notification MethodsTheoretically, removing notification methods should be as easy if not easier than creating them. Afterall, you must populate no fields to conduct the deletion and a button exists for this explicit purpose.But existing relationships between methods and probes can complicate this process. These steps walkyou through it:1. Log into the RHN website as an Organization Administrator.2. Navigate to the Monitoring / Notifications page and click the name of the method to beremoved.3. On the User Details / Notification Methods tab, click delete method. If the method isn’t as-sociated with any probes, you are presented with a confirmation page. Click Confirm Deletion.The notification method is removed.TipSince both the notification method name and address can be edited, consider updating themethod rather than deleting it. This will redirect notifications from all probes using the methodwithout having to edit each probe and create a new notification method.4. If the method is associated with one or more probes, instead of a confirmation page, you arepresented with a list of the probes using the method and the systems to which the probes areattached. Click the probe name to go directly to the System Details / Probes tab.5. On the System Details / Probes tab, select another notification method and click UpdateProbe.6. You may now return to the Monitoring / Notifications page and delete the notificationmethod.
