Hello
<div><br>
</div>
<div>I will try my luck here. Trying to monitor capacity on our gpfs system via observium. For some reason hrStorageTable doesn’t pick up that gpfs mount point though. In diskTable it’s visible but I cannot use diskTable when monitoring via observium,
has to be hrStorageTable (I was told by observium dev). Output of a few snmpwalks and more at the bottom. </div>
<div><br>
</div>
<div>Are there any obvious reasons for Centos 6.7 to not pick up a gpfs mountpoint in hrStorageTable? I’m not that snmp, nor gpfs, savvy so not sure if it’s even possible to in some way force it to include it in hrStorageTable…?</div>
<div><br>
</div>
<div>Apologies if this isn’t the list for questions like this. But feels like there has to be one or two peeps here monitoring their systems here. =) </div>
