We have installed Nagios Xi 5.2.3 fresh on vmware using the ova template.
Imported config files for our switches.
The config files also has mrtg entries in it.
The configuration files are imported successfully
The lookup on the Dashboard shows.
Port 1 Bandwidth Usage:
(Name of the switch)

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

There are a few posts for Installation of MRTG installation for Nagios on Linux.
--------------------
yum install mrtg output shows
Package mrtg-2.16.2-7.el6.x86_64 already installed and latest version
Nothing to do
--------------------
Checked to see if mrtg direcory is available in /var/www/html/mrtg is available
There is no such directory
---------------------
Request your help in resolving this.

Can you post the service definition for the service that is returning that error?

Like I was mentioning this is a new installation of nagiosxi 5.2.3
We have imported the switch configurations from a config file.
The import of the switch.cfg file was successful
the service Port1 Bandwidth Usage gives the error

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

Please find the printscreen attached.

Can you verify the permissions of the /var/www/mrtg/ directory and post the output?

Code: Select all

ls -l /var/www/mrtg/

Can you run the following in a command prompt on the Nagios server and post the output here? I want to see if the nagios user account can run the command.

Code: Select all

su nagios
/usr/local/nagios/libexec/check_mrtgtraf -F /var/www/mrtg/172.16.24.5_10101.log -a AVG -w 1000000,1000000 -c 5000000,5000000 -e 10
While you are logged in, can you run the following and post the output?

Code: Select all

ls -l /var
ls -l /var/www

It look like the new server may needs to have MRTG installed and / or configured on your new system.
If you still have access to the old server, the configs that need to be transferred should be in this folder /etc/mrtg

The issue is resolved.

I changed the permission for
/var/www/mrtg to nagios
by issuing the command
1) chown -R nagios:nagios mrtg

Then the cfgmaker commands below
2) cfgmaker --global 'WorkDir: /var/www/mrtg' --output /etc/mrtg/mrtg.cfg [email protected]
3) indexmaker --output=/var/www/mrtg/index.html /etc/mrtg/mrtg.cfg
4) env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --logging /var/log/mrtg.log

crontab -e
*/5 * * * * env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --logging /var/log/mrtg.log

The mrtg graphs are shown now.

Thanks for all the assistance.
