The OS I am using is CentOS 6.5 64 bit. rrdtool with Perl and Python bindings are installed. Python bindings were missing. After installing all rrdtool packages (ruby, tcl, etc.), it still is segfaulting.

The check_mrtgtraf command segfaults on the logs provided in /var/lib/mrtg with the rrd format.

Do you get any errors, when you run the following command? LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg Runs fine. What mrtg packages do you have installed? If it is a CentOS system, you can run: yum list installed mrtg* mrtg.x86_64 2.16.2-7.el6 @base mrtg-libs.x86_64 2.16.2-7.el6 @base Did you...

This is about all the information the logs are giving me: [1394476809] SERVICE ALERT: netgear-gsm7312;Port 1 Bandwidth Usage;UNKNOWN;SOFT;1;check_mrtgtraf: Unable to open MRTG log file [1394476929] SERVICE ALERT: netgear-gsm7312;Port 1 Bandwidth Usage;UNKNOWN;SOFT;2;check_mrtgtraf: Unable to open MR...

It is not defined. After I posted, I found out that check_local_mrtgtraf is the proper definition. I replaced that and the nagios service started again. Unfortunately it is having issues getting the log which is why I messed with changing check_local_mrtgtraf to check_mrtgtraf.

This is the error that comes up:

While I was trying to configure the check_mrtgtraf command in switch.cfg, somehow it won't let Nagios start now unless I have either the host_name or service_description commented out. I cannot have both uncommented and the service run. I am wondering what issues am I running into here.
