# Viewing Application Alerts

An application alert is displayed in the Management Console application whenever an action with a specific trigger has issued. The trigger rule itself has been set to display the alert in the Trigger Alerts window. You can set rules to trigger an alert in other ways as well, for example, a rule can trigger the sending of an e-mail.

This topic includes information on the following subtopics:

- Opening the Trigger Alerts Window

- Viewing the Trigger Alerts Window Contents

- Using the Trigger Alerts Window

## Opening the Trigger Alerts Window

Depending upon your Java Mission Control Client implementation, do one of the following:

- If you are running the Java Mission Control Client as a standalone application, select Window then Alerts.

- If you are running the Java Mission Control Client as an Eclipse plug-in, click the Triggers tab and click Alerts.

The Trigger Alerts window opens.

## Viewing the Trigger Alerts Window Contents

The Trigger Alerts window lists all alerts that have been generated for applications since Java Mission Control was started on that application. It shows:

- The date and time the alert was raised

- The name of the rule that was violated to cause the alert

- The source of the rule violation. This field identifies the connection for which the trigger was activated. The source is the name of the process denoted in the JVM Browser.

- The Show dialog on alerts condition is on by default and means that the Trigger Alerts window opens as soon as that type of rule has been triggered.

- The Clear button removes all alerts that are listed in the Trigger Alerts window.

## Using the Trigger Alerts Window

The primary purpose of the Trigger Alerts window is to provide you with information about all alerts triggered since the Mission Control Console was attached to a running application (assuming that trigger rules for that application were set).

When you click on an individual alert, information about that alert appears in the alert detail section of the alerts list (Figure: Alert Details). Depending upon the trigger action selected (see "Adding a New Trigger Rule Using the Add Wizard"), different information will appear; for example, if a thread dump was selected as the trigger action, a thread dump would appear here. Figure: Alert Details shows the result of an application alert action.
