6.1 Overview of alarms

Performance Management can be set up to notify the user of when performance data monitored by a monitoring agent exceeds a user-defined threshold.

A definition of how the system should behave when data reaches a threshold value is called an alarm. A set of alarms is called an alarm table. Each PFM - Agent type or PFM -RM type has a folder in which it stores alarm tables.

The folder is displayed on the second level of the Alarms tree. You can display the Alarms tree by selecting the Alarms tab from the navigation frame of the PFM - Web Console Main window.

When the data reaches a threshold value, the monitoring agent reports the information by issuing an alarm event. Performance Management receives the alarm event, and then performs one or more tasks, which are called actions. Performance Management can perform the following actions:

By linking an alarm table to a monitoring agent, you can detect when any thresholds are exceeded. The act of linking an alarm table to a monitoring agent is called binding.

In addition, each monitoring agent can have multiple alarm tables bound to it.
