To configure dynamic alarms for Alarm Policies that will generate alarms by the plugin_metric plugin, the following applies (configured through Operator Console -> Settings -> Alarm Policies):
If your computed baseline is 80 and you want to generate the alarm when the current metric goes above 88% of the computed baseline, you must enter 110 in the dynamic threshold field. The configured threshold will then be 110% of the computed baseline value (88%).
To configure dynamic alarms that will generate alarms by the baseline_engine, the following applies (configured for probes through the Admin Console):
If your computed baseline is 10 and you want to generate an alarm when the current metric goes above 5% of the computed baseline, then you enter a value of 5 in the dynamic threshold field corresponding to the level of the alarm that is to be raised. The configured threshold will then be 105% of the computed baseline value (10.5%).
Manage Alarms with Centralized Alarm Policies
The ${threshold_value} variable description that appears when configuring alarm messages for alarm polices through the Operator Console is incorrect:
This will be corrected in the UIM 9.02 SP1 release.
