I believe the user's original question is to provide the PS generated Job Log/Trace files back to WCC.
The PS standard log/trace file naming convention includes the PROCESS_INSTANCE, (PI), number that the PS Job plugin has captured in its API. It also includes the Process Name and a process specific file suffix. Regardless, the entire path/log is listed in the PS Process Scheduler Run Time Parameters that should actually be included in the AGENT Log! Note that the various process types in PS also use "flags" to specify the log file parm, since each PS Job definition includes the Process Type, then you should be able to determine which log "flag" to look for in the agent log.
