NetXMS Support Forum

I see the below 2 logs happening.  Just wondering what the differences are.  Assuming 'Agent not responding' could be a connection problem and 'Device is down' could be a server crash?  Is it possible to have an 'Agent not responding' message even though the server has crashed and that one would never get the server is down message under this condition?  If that is the case would one receive the message 'Node is up' before 'Connectivity with native agent restored' message would appear.  If you did not get the message reply in this order then chances are the server not crashed.  Both responses get the same integer level of 4.

19-Aug-2012 12:11:35 Critical device 02 (51) Node down 

Hope this makes sense.  Thanks.

Hi!

"agent not responding" means that NetXMS server cannot communicate with agent (but node may still be alive and reachable), and "node down" means that node cannot be reached by NetXMS server with any allowed protocol - agent, SNMP, and ICMP. Usually you get "agent not responding" event before "node down", but it will be correlated to "node down" and will not be passed to event processing policy.
