Why Use AEC?

CA NSM reports messages generated by the failure of managed components to the Event Console. Within the Event Console, message records trigger actions for the failure messages reported. However, some of the messages that the Event Console receives can be misleading or unnecessary. These messages can trigger unnecessary actions to fix false or secondary failures.

Examples of misleading or unnecessary failure messages include the following:

• An expected but normally inappropriate state, such as services taken offline for repairs
• Service failures cause dependent object failures
• System failures cause agent failures
• Repetition of a previously received message

These false failure messages cause problems because message records and actions erroneously generate notifications and trouble tickets, and, therefore, important messages may be lost in all the erroneous, secondary, false messages.

Using AEC, you can do the following:

• Distinguish between primary and secondary failure messages
• Determine the root cause of the failure
• Provide an impact analysis of a failure
• Diagnose and filter unwanted messages
• Respond to dynamically changing environments
