Implement Event Filters

You can control how network events are processed by defining which events are recorded, how they are processed, and what severity alert is generated. You do this by implementing the Event Recording Filters (CNMFILTERS) parameter group.

The use of resource masks restricts the processing of event records to a subset of the network only. The Event Recording Filters parameter group lets you set resource masks for further filtering of records in the selected event type. You can specify any combination of include or exclude mask type for an event type.

To implement the Event Recording Filters parameter group

1. Enter /PARMS at the prompt.

   The Parameter Groups panel appears.

2. Enter U beside the CNMFILTERS parameter group.

   The CNMFILTERS - Event Recording Filters panel appears. This panel has ten pages (each with two types of event filter) that you can scroll through to define filters for each event category. For a list of event types, see Network Error Warning System.

3. Enter the Processing Option and Alert Severity for each event category, if you want to change the default values.

   Note: If you enter an Alert Severity value between 1 and 4, NEWS events appear in the Alert Monitor.

4. Define an Include Mask or an Exclude Mask for each event category for which you want further filtering. For more information, press F1 (Help).
5. Press F6 (Action).

   The entries are actioned.

6. Press F3 (File).

   The settings are saved.

Examples

To prevent an event generating an alert that appears on the Alert Monitor, specify an Alert Severity of 0.

To write an event to the Events Category, specify a Processing Option of E.
