Hi,

Please find below the steps to troubleshoot the problem.

1. Check whether traps are received in snmptt.log(/var/log/snmptt/) file. If traps are not received in snmptt.log(/var/log/snmptt/) file but received in snmpttunknown.log(/var/log/snmptt/) file, then there is some issue with installation of Dell Plug-in. In this case few configuration needs to be done. Follow below steps.

   1. Navigate to /dell/install, and then run the following command:

      ./install.sh trap
      

      Note : is the installed location of Nagios Core and by default, the location of is /usr/local/nagios.

      Restart snmptt service by running below command.

      service snmptt restart

2. Generate traps and check if traps are received in snmptt.log(/var/log/snmptt/) file. If traps are available in snmptt.log file, then ideally the traps will be shown in Nagios console as well. If issue still persists continue with below steps.

3. If traps are not received in either “snmptt.log” or “snmpttunknown.log” file, then there is some issue with snmptt installation/configuration. Check snmptt configuration as mentioned below.

4. Verify whether all the files snmpd.conf, snmptrapd.conf, snmptt.conf and snmptt.ini files are present in /etc/snmp/ directory on the Nagios setup.

5. Check whether "snmptrapd.log" file is present in /var/log/ directory. If present continue with step 6, If not present run below command and then continue with step 6.

   1. snmptrapd -On -Lf /var/log/snmptrapd.log udp:162

6. Check if there is any error in snmptrapd.log(/var/log/) file. If there is any error message, delete snmptrapd.log file and rerun above command by providing different port number. If there is no error in “snmptrapd.log”, restart snmptt service [service snmptt restart]. Now the traps should be shown in Nagios console. Generate trap and check if traps are received in snmptt.log(/var/log/snmptt/) file and in Nagios Console.
