Have you verified that you can query the devices manually from the VM with snmpget?

snmpget –v2c –c <community> <hostname> sysObjectID.0

Subject: [Observium] Using Observium after moving VM

Hello all,

Been scratching my head on this one.  All I did is move the Observium VM from one network to another (closed).  I cannot seem to figure out why I cannot add new hosts.  No firewalls in the way.  SNMP verified running on the host.  Hosts are pinging each other.

Is there a command to verify what is wrong between Observium and a host and why it’s not adding? 

I am using public as the SNMP community name.  One thing that does seem odd is this message when trying to add a host.

No reply on given community *** using v2c, it showing the 3 asterisks versus it saying public.

Any suggestions would be awesome!

Leo
