Hi all,
I'm using Observium r3791 to monitor a few VMware ESXi 5.1 hosts along with a mix of servers and network gear. All seems to be running well, except for the ESX hosts.
When Observium polls the ESX hosts it seems to be missing a lot of information due to missing MIBs:
My /etc/snmp/snmpd.conf has the mibdirs line as per the installation instructions. mibdirs /opt/observium/mibs
It seems if I copy all of the mibs from the /opt/observium/mibs directory to /usr/share/mibs, then the poller seems to run OK. No more missing module errors.
Is this expected behaviour?
Partial debug poller output below:
Observium Poller v0.13.3.3784

The first call to snmpget has the correct MIB path (/opt/observium/mibs), but the 2nd call to snmpget seems to only include the /opt/observium/mibs/vmware (leaving out /opt/observium/mibs)
Consequently I get a lot of errors such as these:
