Performance Graphs Stopped Working

When i remove this two lines, MRTG shows this error.

Code: Select all

[root@nagiosxi5 ~]# time LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
ERROR: could not find RRDs.pm. Use LibAdd: in mrtg.cfg to help mrtg find RRDs.pm

real    0m30.755s

Code: Select all

 [root@nagiosxi5 ~]# locate RRDs.pm
/opt/rrdtool-1.4.4/lib/perl/5.10.1/x86_64-linux-thread-multi/RRDs.pm
[root@nagiosxi5 ~]#

This RRDs.pm is basically the same line that i removed.

When i back everything in prevoius state in mrtg conf

Code: Select all

HtmlDir: /var/www/mrtg

LogFormat: rrdtool

This is output result of time LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Even with MRTG setup with 32 forks, it is taking over 5 minutes to run and it needs to be brought down to less than 5 minutes.
What you can do it to run the following command and look in the /tmp/mrtg.txt file for any unused devices. Then remove the file from the /etc/cron.d folder it it doesn't get checked anymore.

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg -debug=cfg,base &> /tmp/mrtg.txt

Hopefully that will speed thing up.

Just one explanation, which file i need to remove from /etc/cron.d folder?

Code: Select all

[root@nagiosxi5 cron.d]# ls
0hourly  mrtg  nagiosxi  ntpdate  raid-check  sysstat

[tgriep]

Sorry, my mistake, I posted the wrong folder.
After running the command from my previous post, some of the devices will time out and if they do not exist, you can remove the MRTG config file to make the process run quicker.
The configuration files that MRTG uses are in this folder

Code: Select all

/etc/mrtg/conf.d

You can close this topic as resolved. It was to many errors, mostly of some deleted hosts. Now everything is ok.

Sounds good! I'll be closing this thread!

If you have any more questions, feel free to create another thread.

Thanks for using the Nagios Support Forum!
