Hosts reappearing in Unconfigured Items

[RyanMule]

Hello All,

I am currently running into an odd situation. I have been working on trying to monitor a Dell EMC Unity 550f SAN. It only supports v2c and v3 traps. I got Nagios to receive the v2c traps from the SAN. I initially found the host in the Unconfigured Objects list and then from there I configured the host and services and it was working. A few days later the host showed back up again in the Unconfigured Objects and the service checks are not working.

Has anyone else experience this or give some insight?

Thank you
Ryan

Hi, @RyanMule. The SNMP trap could be configured incorrectly.

To further troubleshoot this issue, we would need to see the SNMP configuration files and the MIB files from the server so can you run the following 3 commands as root.

Code: Select all

tar cvfz /tmp/snmp.tgz /etc/snmp/*
tar cvfz /tmp/sharesnmp.tgz /usr/share/snmp/mibs/*
tar cvfz /tmp/snmplog.tgz /var/log/snmptt/*

Then post these 3 files so we can check the settings and the MIB files for any errors.

Code: Select all

/tmp/snmp.tgz
/tmp/sharesnmp.tgz
/tmp/snmplog.tgz

Also, run this as root and post the output to the ticket.

Code: Select all

ps -ef --cols=300

If you know what the Description of the OID the device is sending, add that to the post as well.
Thanks

Hi npolovenko,

Thank you for your reply! As for the trap being configured incorrectly I didn't make any changes on what traps the SAN sends.

I will work on pulling the snmp config files

Thank you
