Collecting data for the Application Debugging workspace

The Application Debugging workspace can help you debug your MQ applications by providing debugging trace data. Data for the workspace is available only if application debug trace is collected on z/OS® systems. PDS data sets must exist at the agent address space. See Enabling PDS data sets at the MQ Monitoring Agent.

About this task

Do the following steps to configure the IBM MQ Monitoring Agent to collect data for this workspace.

Procedure

  1. Enable the optional MQI Monitoring by following the instructions for optional configuration in Optional configuration steps for enabling the Application Statistics feature for the IBM MQ Monitoring Agent.
  2. After the agent is running with MQI Monitoring active, you can issue a KMQCMD to the agent to start trace, such as: 
    F CANSMQ,KMQCMD 
SET APPL NAME(MYAPP) MGRNAME(MQM1) TRACE(YES) TRACELIMIT(1000) STATUS(ADD)
    That command will cause 1000 MQI trace records to be collected for application MYAPP before the trace stops. If you want to trace the same exact entity again, remember to issue the same command except with STATUS(DELETE) first, before trying to do the STATUS(ADD) command again. Note that you can issue these commands from the enhanced 3270UI, which are provided as part of Take Actions to update agent parameters dynamically
