[slurm-users] get job status of completed & cleared jobs from rest interface

[Simone Riggi]

Dear all,
I am writing to ask you a question.

Is it possible to retrieve the status of cleared jobs (e.g. after completed
with either success or failed) from the Slurm rest interface ?

When a job (job id=131 in the example below) is cleared, the rest interface
returns this after some time after completion:

{"meta":{"plugin":{"type":"openapi/v0.0.36","name":"REST
v0.0.36"},"Slurm":{"version":{"major":20,"micro":7,"minor":11},"release":"20.11.7"}},"errors":[{"error":"_handle_job_get:
unknown job 131","error_code":0}],"jobs":[]}

 I activated the job status storage in mysql:

sacct -j 131
       JobID    JobName  Partition    Account  AllocCPUS      State
ExitCode
------------ ---------- ---------- ---------- ---------- ----------
--------
131          testjob.sh     cirasa                     2  COMPLETED
 0:0
131.batch         batch                                2  COMPLETED
 0:0
131.0          hostname                                2  COMPLETED
 0:0
131.1             sleep                                2  COMPLETED      0:0

but the rest service does not seem to pick the status from it.
Do you have hints?

Just to understand more:

- how many seconds the completed job stays available to be queried from
squeue or rest API methods? Can this "time-to-live-before-cleanup" be
configured, eventually increased a bit? This would be useful to avoid
polling the status very frequently.

- do we have a push mechanism to send job status to external web services,
rather than polling it using rest API methods?

Thanks very much for your help,

Cheers,

Simone

PS: Using Slurm v20.11.7 on Centos 7
