Setting Up Alarm-Instance Filters

Before or after you've connected to the servers from which you want to retrieve alarm instances, you can set up one or more alarm-instance filters, per server. These filters control which alarm instances are displayed in the NerveCenter Client. You can filter alarm instances by:

• The IP address of the instance's node
• The severity of the instance's state
• The property group associated with the instance's node

If you filter alarm instances by a severity, only instances whose states have this severity will be displayed in the client. Filters based on property groups and IP address ranges work similarly.

A single filter can contain any combination of:

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

These filters offer two advantages. First, they limit the number of alarm instances that will show up in the client, enabling you to focus your attention on the alarm instances that are specifically of interest to you. Using filters also improves the performance of the client, since NerveCenter only transfers to the client those alarm instances that match the filter criteria.
