We need to disable "Queue Manager Clusters" because this metric groups have a lot of metrics and we do not monitor these. We monitor queue managers with "Queue Managers" metric groups.
Release : 10.7.0
Component : APM Agents
When monitoring MQ Servers and MQ Clusters using the MQ Monitor agent, if Queue Manager is a part of a Cluster of queue managers, then the MQ Monitor agent will be reporting metrics twice for all the queues, channels etc. under the Queue Manager Clusters and Queue Managers branches. This information comes directly from the MQ and the filters available in the properties file of the MQ Monitor agent would not allow to filter out the duplicated queue-manager, channels, queues, etc. from either of the two branches.
There is an option of "Shut Off" metrics in the investigator. Please review the details here.
Check if this works for you. Please use it carefully.
