<p class="MsoNormal">Hi,<br>
<br>
We’ve been using the <i>sreport cluster utilization report</i> to report on <i>Down</i> 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.<br>
<br>
Most of the time the figure that comes back is one that fits the perception of the day to day running of the cluster.<o:p></o:p></p>
<p class="MsoNormal"><br>
We don’t log node UP/DOWN in any way (beyond what slurm does) and rely on <i>sreport</i> as explained above.<br>
<br>
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.<br>
<br>
Is anyone else relying on <i>sreport</i> for this metric? If so have you encountered this sort of situation?<br>
<br>
<o:p></o:p></p>
