Re: [HTCondor-users] Job status of jobs when using USER_JOB_WRAPPER

[Weiming Shi <swmtrc@xxxxxxxxx>]

Hi Brian,

Thanks for your detailed explanation.

To clarify my question a little. By JobStatus, I mean the ST field
returned by 'condor_q -nobatch' query from a submit node. It seems
that this JobStatus is not designed to match the STAT field (i.e.,
PROCESS STATE CODE) that could be collected by the 'ps aux' query on
the condor execute node where a job is executed.

Is there a easy way for a user to know the exactly the PROCESS STATE
CODE of the process that execute a job other than issuing remote ssh
command?

Thanks
