Re: [HTCondor-users] PID of a running job

[Ricardo Oda <odaric@xxxxxxxxxx>]

Thanks for the reply,

Well I'm not familiar with these hooks, maybe I'll take a look.

Though I finished my implementation using cgroups and looking at the folders.

It's not that bad, condor creates a sub-folder for each busy slot and all the running-jobs pids are stored there (while it's still running).

Thanks again,

Ricardo Oda

Hi Ricardo,

I've been trying to come up with a clever way to do this, but I've not been able to come up with something simple.

Here's something not-simple:

- Use the "update job info" hook (http://research.cs.wisc.edu/htcondor/manual/v8.3/4_4Hooks.html#SECTION00541100000000000000) to get information about the running job.

- From within the update hook script, invoke /usr/libexec/condor/condor_chirp to push a JobPid attribute from worker node to schedd.

Hello,

Is there a good programmatically way to get the os process id (PID) of a running job on the host machine? I've not found a classad that shows it.

The way I'm working right now is using cgroups and monitoring the child groups (folders) of the my BASE_CGROUP, but maybe there's a simpler/easier way.

Thanks,

Ricardo Oda
