Issue/Introduction

MQ and MB Agent registering zero values inside Investigator for execution groups nodes, even CPU metrics are having these behavior.

Environment

Any CA Application Performance Management Agent Release.

Cause

This happens because the MQ/MB server are set the record type as "Archive", this way store queue managers metrics every "X" minutes instead 15 seconds as default.

Resolution

To change this behavior, MQ/MB server must have record type set "Snapshot", this way Introscope will receive the metrics and plot it in real time instead every 10 minutes.

To adjust MQ/MB server, please do the following:

1) Run below command to switch from "Archive" to "Snapshot" inside MQ/MB server.

mqsichangeflowstats <BROKER1> -s -g -j -c active -o xml -n basic

2) Make sure to have MBmonitor.properties configured to process data as "Snapshot":

statistics.broker.recordtype=snapshot

3) Restart MQ/MB server to make the new configuration take effect.
