[slurm-users] Validating SLURM sreport cluster utilization report

[David Simpson]

Hi,

We've been using the sreport cluster utilization report to report on Down time and therefore produce an uptime figure for the entire cluster. Which we hope will be above 99% or very close to, for every month of the year.

Most of the time the figure that comes back is one that fits the perception of the day to day running of the cluster.

We don't log node UP/DOWN in any way (beyond what slurm does) and rely on sreport as explained above.

The December figure we have is lower than 99% and there are 438 slurm nodes in the cluster. In December we only remember having problems with 3 nodes. So at the moment off the top of the head we don't understand this reported Down time.

Is anyone else relying on sreport for this metric? If so have you encountered this sort of situation?

regards
David
