Products

• Mainframe Operational Intelligence

Issue/Introduction

Alarm Suppression doesn't occur despite creating alarm suppression entries in the alarmSuppressor.csv file. 

 

 

 

 

 

 

Environment

Release : 2.0.0*

Component : MTC OPERATIONAL INTELLIGENCE UI

Resolution

The alarm suppression entries are manually made to the alarmSuppressor.csv file located in the following directory on your MOI appliance:  var/opt/moi/config/profiler/etc/opt/CA/itoa/profiler/alarmManager/

Here are helpful hints to avoid the alarm suppression entries not being applied correctly:

 

First Big Hint:    The first line of the alarmSuppressor.csv file must be the header line:      METRIC_NAME,SUPPRESSED_SEVERITIES,MIN_THRESHOLD

If this line is missing from the alarmSuppressor.csv file, alert suppression will not occur at all and the following error messages will be repeated over and over in the profiler-alarm-manager.log located

in the MOI appliance folder, /var/opt/moi/data2/profiler/var/opt/CA/itoa/profiler/logs   :

Please stop and start the alarm manager microservice using the MTCAC UI as shown below to ensure your changes are applied.  Please wait until the alarm manager microservice starts up and reaches a healthy status to verify the alarm suppression entries are working.
