Hi Hogan
i fully understand where you are coming from now and i thank everyone for there help and advise :)
Question, if did put multiple ip addresses in the DNS and say for instance the first IP it tried is down (no reply)
would it simple move onto the next ip as when it queried the DNS name it has multiple ips or would it just say OH NO server down...?

DNS RR does not turn it into a traffic load balancer. You’re confused if you think that DNS RR functions anything like a load balancer where traffic may come in on one interface and leave on another. I do understand your concern, though. If the router has a route to the Observium host via one interface and an SNMP query comes in on another interface then that won’t work, but that’s not a problem with DNS RR. That’s a problem with the device and network configuration itself and the problem would exist whether or not someone were to use DNS RR. If Simon can currently and reliably query the device using any of the IPs configured then creating a DNS RR entry to rotate through them won’t make any difference. The only issue is as I mentioned before, if the IP changes or one of the links goes down then a portion of the SNMP queries will fail whenever the bad IP comes up in the DNS rotation.

The SNMP traffic must come in and go out the same interface.

Hi All,
this is a daft random question, can i monitor a device via multiple ip addresses?
for instance, we have a site with a mikrotik router,
they currently have 3 internet lines (DONT ASK!) 2xADSL,1xFTTC
currently we use PPPOE on the router so we can see the mikrotik directly,
ive enabled SNMP remotely and i monitor the box via 1 of the ADSL lines, however its constantly goes up and down and never makes up its mind!
Mikrotik's don’t like asymmetrical SNMP traffic sort that out and it might come right.
