1 Alarm Definition

The Alarm Definition section under Monitoring allows you to define alarms that are useful in generating notifications and metrics required by your organization. By default, alarm definitions are sorted by name and in a table format.

1.1 Filter and Sort

The search feature allows you to search and filter alarm entries by name and description.

The check box above the top left of the table is used to select all alarm definitions on the current page.

To sort the table, click the desired column header. To reverse the sort order, click the column again.

1.2 Create Alarm Definitions

The Create Alarm Definition button next to the search bar allows you to create a new alarm definition.

To create a new alarm definition:

  1. Click Create Alarm Definition to open the Create Alarm Definition dialog.

  2. In the Create Alarm Definition window, type a name for the alarm in the Name text field. The name is mandatory and can be up to 255 characters long. The name can include letters, numbers, and special characters.

  3. Provide a short description of the alarm in the Description text field (optional).

  4. Select the desired severity level of the alarm from the Severity drop-down box. The severity level is subjective, so choose the level appropriate for prioritizing the handling of alarms when they occur.

  5. Although not required, in order to specify how to receive notifications, you must be able to select the method(s) of notification (Email, Web, API, etc.) from the list of options in the Alarm Notifications area. If none are available to choose from, you must first configure them in the Notifications Methods window. Refer to the Notification Methods help page for further instructions.

  6. To enable notifications for the alarm, enable the check box next to the desired alarm notification method.

  7. Apply the following rules to your alarm by using the Alarm Expression form:

    • Function: determines the output value from a supplied input value.

    • Metric: applies a pre-defined means of measuring whatever aspect of the alarm.

    • Dimension(s): identifies which aspect (Hostname, Region, and Service) of the alarm you want to monitor.

    • Comparator: specifies the operator for how you want the alarm to trigger.

    • Threshold: determines the numeric threshold associated with the operator you specified.

  8. Match By (optional): group results by a specific dimension that is not part of the Dimension(s) solution.

  9. To save the changes and add the new alarm definition to the table, click Create Alarm Definition.
