In the development of the cluster management system, we use PBSPro as a tool for job management, how to get the job information in real time, through the database or command line query?

If you want to get the details from another program, IFL are the way to go.
You can find more details from the Programmer’s guide.

PBS_IFL access from Python, if it helps.

Pbs_ifl access from python

I’m trying to use pbs_ifl routines from python, but keep running into deadends. I started with a git clone of 18, configured it (with a private --prefix), built it (with some hacking involved due to missing RPMs), and installed the pieces that built. Now running pbs_python via: env PYTHONPATH=$HOME/PBS_18/lib/python/altair \ LD_LIBRARY_PATH=$HOME/PBS_18/lib \ $HOME/PBS_18/bin/pbs_python --hook -i hook.input I get: pbs_python: No such file or directory (2) in pbs_python_ext_alloc_python_scri…

If you are looking for Asynchronous job status notification, this feature is not available yet. See the thread for details:

Asynchronous Job Status Notification

For a while now I’ve been kicking around the idea of having an async notification system for job statuses. I’ve seen many applications which are built on top of pbs that submit jobs and then continually poll the server to query the status of their submitted job(s) at some fixed interval. This seems a little inefficient. I’m envisioning a notification system that is offered by IFL where client applications can “subscribe” to jobs which they wish to be notified about, and the server simply send…

Relying on PBS database for real time information will not help as jobs and other structures are not immediately saved to database due to operational costs. It is maintained in the program memory.
