Usage Guidelines
Usage Scenario
A lot of alarms are generated and then reported on a running system. If non-root-cause alarms are unimportant, you can enable NMS-based alarm correlation suppression to filter out non-root-cause alarms.
Prerequisites
The alarm correlation analysis has been enabled using the correlation-analyze enable command.
Example
# Enable the alarm correlation suppression of the NMS host whose security name is user123 and IP address is 192.168.3.1.
