To Create an Alarm Condition
The following example procedure shows how to create a simple alarm. This example creates an alarm condition when the system load over the past five minutes exceeds a specified value.
-
Select a data property table from the Host Details Browser page.
For this example, select the System Load Statistics table in the Kernel Reader (Simple) module.
-
Choose a specific data property in the data property table.
For this example, select the value for the Load Average Over Last 5 Minutes property.
The Attribute Editor appears for the selected data property.
-
Click on the Alarms tab in the Attribute Editor window.
The Alarms page appears.
-
In the Critical Threshold (>) field, type an appropriate value.
For this example, type .050. This value is probably lower than what you would normally use, but will most likely generate an alarm to illustrate the process.
-
Click OK to apply your changes and close the Alarms tab page.
In a few moments, the Load Average Over the Last 5 Minutes data field in the System Load Statistics data properties table turns red. In addition, red alarm icons appear on the following folders and icons, unless your system has an open, unacknowledged black (down) alarm:
-
Operating System
-
Kernel Reader
-
System Load Statistics
Click Reset to reset the Attribute Editor to the default parameters.
-
-
Click the Host Details Alarms tab.
The alarm that you created is reflected in the alarms table when the table is refreshed.
-
Acknowledge this alarm.
-
Create additional alarm thresholds. Then, familiarize yourself with their operation.
Once you have created these alarms, you can set up security permissions so that another Sun Management Center software user cannot change your alarm thresholds. For more information about security, see Chapter 18, Sun Management Center Security.
Tip –You do not need to fill in alarm information for all alarm thresholds. For example, you can choose to create only a critical alarm threshold.
