      This can be captured using the command 'mqsiservice -v'..
    • Record the operating system version, release, and maintenance level.
    • Record the version, release, and maintenance level of any related products and components for the problematic application.
    • Collect the local error log. On Windows systems, the local error log is the Windows Event viewer application logs.
      See: Windows Event viewer logs
    • Collect the console.txt
      WMB writes information to console.txt. This file is located under the Message Broker workpath.
      See: Standard System Logs
