Been getting a lot of SNMP timeouts lately. FreeBSD/Nagios has been up and running for 60 days. Mikrotik CCR has been up and running for 42 weeks (nope, no updates for a long time).
Today, we keep getting alarms that SNMP is timing out. I try it from the command line, and I get this:
$ snmpwalk -v2c -c SuperSecret 172.28.28.1 1.3.6.1.2.1.2.2.1.8
IF-MIB::ifOperStatus.1 = INTEGER: down(2)
IF-MIB::ifOperStatus.2 = INTEGER: up(1)
Timeout: No Response from 172.28.28.1
Trying several times, I’ll get a timeout right away, maybe I’ll get 5 or 6 interfaces. Usually, within a few minutes, the query will complete.
Profile shows 96.4% idle, SNMP at 0%.
Any ideas on why SNMP would be timing out?
I don’t care to upgrade (yet). This beast has been running fine for 42 weeks without this problem. I do not see why it would start acting up now.
Thanks!
