I’m trying to monitor a few foundry XMR’s via SNMP, however I’m experiencing issues where the XMR is VERY slow at responding, if it responds at all. I’ve confirmed it’s not an ACL issue (there’s no receive ACL, etc) and the CPU while a little busy, is not crazy.
(40%usage overall, SNMP only tacking 1% average). snmpget’s timeout 3/4 of the time. snmpwalk’s are impossible, as even if a few values are returned, it will inevitably time-out before it reaches the end.</div>

I must admit I’m a bit new to the XMR platform, can anyone let me know what I could check regarding this?</div>
