almost the same as original check_mrtgtraf but this one works and is "fine tuned" to give detailed output on which IN or OUT threshold was exceeded, it is also "fine tuned" to present the output in Mbyte and/or Kbytes depending on how much traffic there was. You can tell the program what "unit" the WARNING or CRITICAL thresholds will be in. The script supports input as kbytes, mbytes, gbytes or tbytes. Don't forget to edit the file to point to the directory where your utils.pm is located. Find and Change below line. use lib "/usr/local/nagios/libexec";

-|--f|F|FUN|FUNCTION|function Can be either AVG or MAX. where AVG = "The average incoming transfer rate in bytes per second" AND MAX = "The maximum incoming transfer rate in bytes per second since last MRTG poll" (DEFAULT AVG)
-|--w|W|warn|WARN|warning|WARNING This will tell Nagios when to send a WARNING message. WARNING Threshold expects bytes input as default(unless you use the -u flag) and needs to be supplied as a "warning threshold pair" <incoming>,<outgoing>. If there is only one value passed in it will use that value in both pairs. (NO DEFAULT)
-|--c|C|crit|CRIT|critical|CRITICAL This will tell Nagios when to send a CRITCAL message. CRITCAL Threshold expects bytes input as default(unless you use the -u flag) and needs to be supplied as a "critical threshold pair" <incoming>,<outgoing>. If there is only one value passed in it will use that value in both pairs. (NO DEFAULT)
-|--|u|un|UNIT If you don't want to pass in WARNING and CRITICAL threshold pairs using default "bytes input" then use this flag to change it to suit your need. This script understands Kilobytes, Megabytes, Gigabytes and Terabytes. Input is regexped so can be anything from <k|kilobytes> or <m|megabytes> or <g|gigabytes> or <t|terabytes>. If this flag is not used THEN scripts expects input for WARNING and CRITICAL thresholds to be in bytes.
-d|D|DEBUG|debug : Enable debugging (DEFAULT disabled)
-|--he|HE|help|HELP Prints this help screen
-|--v|V|VERSION|version Prints program version
INFO: WARNING THRESHOLDS must be exceeded before any checks are done on CRITICAL THRESHOLDS! Also only use the debug flag from the CLI Nagios will be very confused by it. If you find any BUGs or have a suggestion on a feature or improvments then please drop a line to [email protected]
IMPORTANT!! For this scripts to work with Nagios! This script needs to be able to find nagios supplied utils.pm file. Edit this file at the top of the file change "use lib qw( /usr/local/nagios/libexec );" to point to where you Nagios installation installed utils.pm. IF you get errors looking like "Global symbol "%ERRORS" requires explicit package name" Then it is a sure sign that your path to utils.pm is wrong.

+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
