check_mrtgtraf

+1 for the user who submitted "script to obtain check_mrtgtraf performance data needed by NagiosGraph"
https://exchange.nagios.org/directory/Plugins/%2A-Plugin-Development-Tools/check_mrtgtraf/details#rev-3196

Using that, as is, even though it is written in Spanish, I was able to pop it in as a proxy script to check_mrtgtraf and it works out of the box for me using Graphite, Whipser, Grafana! Thanks for that contribution!!!

I wrote this script that modifies check_mrtgtraf output in order to obtain usable performance data usable by nagiosgraph.

I hope it will be useful.

Hello,

I started to use this script, and it looks good to use easier than the original one. My only problem is, that the pnp4nagios stopped working and doesn't want to make the graphs anymore. Don't you have any idea about it?

Thank for the great script!

Regards,

Tamás
