We have a group of servers with high usage of cpu and network (with 10 Gb bandwidth). Under this circumstances snmpwalk requests to this servers got timeout. So we can't monitor them.

The question is how to help snmp service to respond to requests?

I already tried to increase snmpd process' priority with renice command but nothing changed

    How many object do you get with snmpwalk ? Try to limit to the minimum – Dom Jan 3 '18 at 8:26
  • good advice! I will try it and let you know – vakarami Jan 3 '18 at 8:32
  • @Dom I walked on single oid but I didn't get any result, same as walking on large oid! – vakarami Jan 4 '18 at 7:51
  • Maybe try in TCP (SNMPv3) if possible : the UDP packets maybe lost if the network link is full – Dom Jan 4 '18 at 12:11
  • @dom using TCP makes response time faster, but not fast enough! I think we must add another network for monitoring purposes, because current network is fully saturated! – vakarami Jan 13 '18 at 9:40
