Filtering Alarms by Severity

When you filter alarms by severity, you are specifying that you only want to display alarm instances in the NerveCenter Client from particular nodes identified by the severity of the alarm instance's state.

Although you can create a filter simply based on severity, a single filter can contain any combination of:

• A list of subnets
• A list of severities
• A list of property groups

For information on how to build an alarm-instance filter based on IP range and property groups, see the respective section listed below:

• Filtering Alarms by IP Range
• Filtering Alarms by Property Groups

 
  To create an alarm filter based on severity:

1. Choose Configuration from the Client menu.

   The Client Configuration dialog is displayed.

   Client Configuration Dialog

   

2. Select the Alarm Filter Modification tab.

   The Alarm Filter Modification page is displayed.

   Alarm Filter Modification Page

   

3. Select the New button.

   The Alarm Filter Definition dialog is displayed.

   Alarm Filter Definition Dialog

   

   This is the dialog you use to define your filter.

4. Select the Severity tab.

   The Severity page is displayed.

5. In the Available Severities list, for each severity you want to use in your filter, select the severity and then select the >> button. That is, you want to see information about alarm instances whose states have these severities.

   The severities in this list box are the union of the severities defined by all of the servers to which you're connected. Optionally, you can also add a user-defined severity to the list of severities to filter by entering a severity in the And User-specified Severity text box, and then selecting the >> button.

   The name of the severity is moved to the Selected Severities list. Information about alarm instances with this severity will be displayed in the alarm summary views.

   To remove a severity from the Selected Severities list, select the severity and then select the << button.

6. Enter a name for your filter in the Filter Name field.
7. Select the OK button.

   The Alarm Filter Definition dialog is closed and you return to the Client Configuration dialog box.

You've now defined an alarm filter based on severity. Before the client will use the filter, however, you must associate the filter with a server. For instructions on how to create this association, see the section Associating a Filter with a Server.
