Problems with Nagios CORE

[jsoar]

Hi everyone!

I have two problems with Nagios Core. I have a Debian server and I try to monitor a Mikrotik router:

check_mrtgtraf: Unable to open MRTG log file
Usage check_mrtgtraf -F <log_file> -a <AVG

SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m RFC1213-MIB -v 1

Let's start with the mrtgtraf first:

Please post the output of the following:

Code: Select all

ls -ld /var/lib/mrtg
ls -l /var/lib/mrtg

For the SNMP problem can you run nmap (from the Nagios machine) against the server in question to see if it is reachable? Run this cmd on your Nagios box:
nmap -sU -p 161 hostname\IP

*Keep in mind that we may have open a new thread for the SNMP problem should we have to do extensive troubleshooting for either issue.
