Hi Team,

We are trying to configure snmp trap monitoring for ESX server for hardware monitoring. The team is sending the the traps to nagios server but we are not receiving the traps on the snmpttunknown.log. When i did the snmpwalk on the remote device we can see the output.

Hello, @sandeep.endla.
Please go over the Install SNMPTT on Nagios XI SNMP Receiver Server section of this tutorial:
https://support.nagios.com/kb/article.php?id=77
And also, please upload the /etc/snmp/snmptt.ini file here.
Are there any firewall limitations between these two servers?

Sorry for the delayed response.

We are have configured the snmp traps for the server on ip (172.21.46.100-NAT-IP). we are receiving the trap in snmptt.log but the log file is having traps with 10.199.96.111 this is the real ip of (172.21.46.100 -NAT IP). But we are unable to see the traps in unconfigured objects in Nagios XI console. How to add the server for SNMP traps monitoring.

@sandeep.endla, Do you see anything in /usr/local/nagios/var/nagios.log file when XI is receiving SNMP traps?

Hi npolovenko,

We are not reciving any traps on the nagios.log . please find the below snip

I am going to assume you followed this document to setup SNMP Traps
https://support.nagios.com/kb/article.php?id=77


Please upload the following for review
/etc/snmp/snmptt.conf
/etc/snmp/snmptt.ini

Hi Scottwikerson,

Please find the below snmptt config files. Other thing is we are unable to find EXEC in the processed MIBs. Please find the below snip.

This clearly wasn't setup using our script or you would have different EXEC lines

Please see this doc,
https://assets.nagios.com/downloads/nag ... ios_XI.pdf

it must be setup using the NagiosXI-SNMPTrap-setup.sh script

Also see page 2 about running the addmib command to add new MIBs after setup

I have runned the same script NagiosXI-SNMPTrap-setup.sh on the nagios and for snmptt i have installed snmptt-1.4-0.9.beta2.el6.noarch.rpm on the nagios. i have these files generated on the nagios which are attached.

these are the exact same file size as before

run the following
