Nagios Support Forum

Hi,
I have installed Nagios XI 5.6.5 and added about 500 host and have 6000 services related to the hosts. I use passive check (SNMP Trap), I faced with issue from two days ago.
I receive traps by delay in snmptt.log ( the delay is around 1.5 - 2 hours) it seems the snmptt is very busy and when I try to restart the service , it takes more than 1 minutes.
when I checked system resources, it was in normal situation but snmptt process and after it snmptrap process are highest processes of ssytem.

I don't know what is problem and I don't know how to find cause of the problem.
would you please guide me to find reason of the issue.

Thanks
Parisa

There is a default sleep setting in the /etc/snmp/snmptt.ini file that could be causing the delay after all of the additional traps that are being received now.

This it the option description and the default setting. What I thing it that in 5 seconds, there are so many new traps received that the snmptt daemon cannot process them all in 5 seconds so to fix this, change that setting to 1 second and restart the snmptt daemon.

That will allow the daemon to process the traps every 1 second and hopefully it can keep up with the extra traps.
