SNMP timeouts are almost exclusively caused by the end devices or the network.

If it’s not the end devices being useless, it’s often an intervening firewall getting angry at the UDP traffic.

There’s almost nothing on the Observium server’s end that’d cause this sort of thing.

Subject: [Observium] SNMP Timeouts

Hello,

A couple of weeks ago some of our switches starting not responding to SNMP and are showing down now but I can ping them from the server that I have Observium on. Recently the server storage got filled up but I expanded the disk and has plenty of space now, but I still get timeouts even if I run the SNMPwalk from the Obserivum server. I reinstalled the snmp and snmpd packages on the server (ubuntu 20.04). Some switches are using v2c and those are working while the ones that aren’t working are using v3.

Wasn’t sure if maybe I needed to reinstall some other packages or see what else I could do to fix this.

Thank you
