Nagios Support Forum

Posted: **Mon Aug 28, 2017 3:26 am**

Recently i noticed a little problem with graphs in Nagios XI, from time to time graphs show values 0Mbps, and after 1-2 hours value is ok. This is problem because i need really presize graphing.

This is how graph for this service looks when it was everything ok, and the other picture is actually state.

it looks like you could be hitting thresholds with performance - have you thought about implementing a ramdisk for your performance data processing? it'll help with the mass amount of smaller files.

the other option is increasing the timeout - https://support.nagios.com/forum/viewto ... 742#p76165

If the graphs that are showing 0mbps are only wrong for bandwidth graphs, the other cause of that issue is the MRTG process that gathers the bandwidth information for XI.
To troubleshoot that, can you run the following command as root and either post or PM me the /tmp/mrtg.txt file?

Code: Select all

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

If other non-bandwidth graphs are displaying zero, then the link @tacolover101 posted should help out with them.

The problem is with only bandwidth graphs, non bandwith performs normally. I tried to implement ramdisk, and increase a threshold but problem still persist.

@tgriep
Because of file limitaion in PM, i'm attaching MRTG file here as zip, because original file is about 100MB.

I am thinking that the time it takes to run the MRTG application is taking over 5 minutes and that they are not finishing in time so lets increase the number of processes so it will finish quicker.
Edit this file.
/etc/mrtg/mrtg.cfg and change this line from

Code: Select all

Forks: 4

to

Code: Select all

Forks: 12

Save the file and restart cron by running

Code: Select all

service crond restart

That will triple the number of processes so it will finish quicker.

Another cause it that when it runs, it opens so many files, it exceeds the open file limit.
To fix that edit this file /etc/security/limits.conf
Add or edit the following lines to the end of the file:

Code: Select all

* soft nofile 10000
* hard nofile 10000

Save the file and you may have to reboot the server for the changes to take effect.

It seems that everything is ok now, thank you for explanation.
