Nagios Support Forum

I am sorry if there is a solution already and I missed it but I tried everything and I could not get it working.

I think MRTG is working as I can see only one graph here but error in nagios Core Version 4.0.8.
http://192.168.3.2/mrtg/index.html

Permissions are as follows

-rwxr-xr-x 1 nagios nagios 110343 Oct 2 14:50 /usr/local/nagios/libexec/check_mrtgtraf

I have spent over a week on it. FYI I am just a beginner on Linux but I can find my way around thanks to all your help.

Can you show us the cron that you currently have set up? Can you also manually run the command that you have in that cron and show us the output?

Here is the output:

[root@nagios ~]# */5 * * * * /usr/bin/env LANG=C /usr/bin/mrtg /etc/mrtg/mymrtg.cfg –logging /var/log/mrtg.log
-bash: */5: No such file or directory
[root@nagios ~]# */5 * * * * /usr/bin/env LANG=C /usr/bin/mrtg /etc/httpd/conf/mrtg.cfg --logging /var/log/mrtg.log
-bash: */5: No such file or directory
[root@nagios ~]#

This morning I changed my service def as well to
define service{
use generic-service
host_name Master
service_description Port 1 Bandwidth Usage
check_command check_local_mrtgtraf!/var/www/mrtg/192.168.3.40_1.log!AVG!1000000,2000000!5000000,5000000!10
}
and restarted nagios service. Now I get MRTG data has expired (5619 minutes old) .

Sorry it has gone back to same error
check_mrtgtraf: Unable to open MRTG log file

You can't run that command as it is posted in the crontab, you need to run it as a typical linux command:

Hi,
Just run it or copy it in cron?

You need to run the command that slansing posted from the command line, and post the output.

I have run the command and I did not see any output
[root@nagios ~]# /usr/bin/env LANG=C /usr/bin/mrtg /etc/mrtg/mymrtg.cfg –logging /var/log/mrtg.log
[root@nagios ~]#

What is the output of:
I'm curious to see both the permissions, as well as the size and last update time.
