HP SIM does not receive traps from other systems

[TomSc_2]

Hi there,

since some weeks, my HP SIM does not receive traps from the monitored systems anymore.
I receive events that systems aren't available or that they are back online, but I don't receive any information on failing hard disks and so on.
It seems as if HP SIM would not pick up the SNMP Traps anymore.

I already verified that such traps successfully arrive at my HP SIM box, but HP SIM does not recognize them...
I enabled the option to receive unregistered traps and I activated all the severity levels.
I also allowed all hosts to send traps to this box.

I already read many messages here, tried to re-activate the monitoring but nothing helped.

Does anyone have an idea what might be the reason?

I use HP SIM 6.0 on a OpenSuSE Linux box.

All the status displays are working fine. It's just the traps...

Best regards,
Tom

Today I found this in the logs:

02 May 17:12:42,666 INFO [HPSIM_DEBUG] [Status-0] (main) ********* Executing DATA INIT PHASE ONE **********
02 May 17:12:43,017 INFO [HPSIM_DEBUG] [Panic Logger-0] (main) [the cms node] does not have the primary DNS name configured properly

Maybe this can help.
The HP SIM server has an entry in the DNS server and thus should have a FQDN...

I found out why the DNS error message appeared.
I had the following line in my /etc/hosts:

10.20.30.40 hpsim hpsim.domain.name

after changing to

10.20.30.40 hpsim.domain.name hpsim

this error disappeared.
But the issue with the snmp traps is still there.

Now the error message is:
03 May 14:42:53,248 INFO [HPSIM_DEBUG] [Status-0] (main) ********* Executing DATA INIT PHASE ONE **********
03 May 14:42:53,887 INFO [HPSIM_DEBUG] [Status-0] (main) SNMPREQUEST: Trap Listener: 0.0.0.0 Port: 162

INFO: Binding to UDP port:

when issuing "netstat --ip -poan | grep 162", the following is displayed:

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State

udp 0 0 0.0.0.0:162 0.0.0.0:* 6445/mxdomainmgr off (0.00/0/0)

It seems as if the only process binding to port 162 was mxdomainmgr, but there is no state displayed (e. g. LISTENING).
