Every active integrated Windows server has a monitor job that starts when you start the server. The monitor job runs in the QSYSWRK subsystem under the QSYS user profile. The job name is the name of the network server description that it is monitoring.
When the monitor job starts, i5/OS™ sends an informational message, CPIA41B, to the QSYSOPR message queue. This message contains the job ID of the monitor job. You can use this job ID with the Work with Job (WRKJOB) command to find the monitor job log and other job-related information for the monitor job.
