check_snmp unable to return GAUGE32 from HPE SAN
Posted: Tue Jun 25, 2019 5:53 am
Hello everybody,
I'm trying to use Nagios Core to monitor a HPE StoreVirtual 3200 SAN via check_snmp, spesifically, I want to monitor the amount of memory that the device is utilizing. I've acquired the correct MIBs from HPE's website (in relation to the device's firmware version) and I've moved them to /usr/share/snmp/mibs/ with correct permissions.
I know that monitoring the RAM is possible, because HPE informed me with an email, that by updating the firmware it would be possible:
When using a free MIB explorer, I was able to the OID that I was looking for:
However, I cannot fetch this using check_snmp for some reason. I'm a little rusty with OIDs, so I tried adding a zero to the end:
In addition to all that, there is another Memory OID which works fine but it returns a STRING and not an integer value so I can't make Nagios send an alert if a certain threshold is reached:
And it works fine:
Any help would be much appreciated as I have to make this work one way or another.
