Are the log files showing up in this folder? /var/www/html/mrtg/ Yes, all in the same Folder. The problem is that with your configuration and cron task now no one of the 3 Switches is updating the mrtg.log files. So I reused the old one: */5 * * * * /usr/bin/env LANG=C /usr/bin/mrtg /etc/mrtg/mymrt...

I think that I found the problem. In another site I found that the mrgt can update only 1 Switch at time (I got 3 Switch to Monitor). The only thing I had to do was modify some of the file location paths. Since I am monitoring multiple switches I had to modify some things. Using the "env LANG=C...

In your crontab file, you have 2 entries, you should delete the bad entry and that should fix the email errors. Can you post how your check_mrtgtraf command is defined and also your service check that is generating the error. # 'check_local_mrtgtraf' command definition define command{ command_name ...

After I install the Plugin/Nagios it seems ok.

I resolved the "SNMP Plugin error" with installing some SNMP modules on Centos.

Now I have only the error with Nagios/Plugins.pm.
Don't know what is this "Nagios/Plugins.pm.

The Problem was that in the Contacts files there was a duplicate "notify-host-email". Don't know why nagios didn't tell me that before.

By the way, there is a way to DISABLE only the "Recovery" E-Mails? I need only the Warning - Critical E-Mails.

Hello, after I reinstalled Nagios Core on a New Centos 6.7 VM, some of my plugins get this error: https://i.imgsafe.org/f7995b1.jpg [root@nagioscorefx libexec]# ./check_esx3-0.5.pl Can't locate Nagios/Plugins.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/v...
