Nagios Support Forum

Hi Guys,

I would like to know if I can somwhow customise the metric plugin to monitor other services rather than just those fixed few items. I have been searching the plugin code to find where it grabbing the data from but so far havent had any luck! Any pointers would be really appreciated.

Many Thanks
Arnab

That one is going to be a bit of a trick to customize. The component relies on the backend set of functions in the file:
/usr/local/nagiosxi/html/includes/utils-metrics.inc.php

The main index.php file of the component handles the front-end aspect of it.

The dashlet html-build functions are also in the metrics.inc.php file.

Hi Mike,

Thanks for the pointer after looking at the code I do understand what you meant , just want to know one last thing I can see that its doing a pattern match for the perf data. Can you tell me if I have a perfdata output of somthing looking like this "'wap-Lodge-Dorm'=1;25;30;0; 'wap TH middleKroom'=0;25;30;0; 'wap NH2'=3;25;30;0; 'wap Art Loft'=0;25;30;0; 'wap ArtPottery'=0;25;30;0; 'wap US Library CubbyHoleStacks'=1;25;30;0; " What should i be searching for ?

Cheers

I don't suppose we're lucky enough that "wap" is unique to this kind of metric?

Nah,,I wish ! Not at the moment but I can always manipulate the plugin so that output contains something uniq on which we can pattern match will that help ?

Yeah, I would go that route. Have the either the plugin output or the performance data label something unique. The simpler you can keep the regular expression match the faster it will perform, that and you won't have to write such a horrible regular expression to match it.

Also, I don't think you can do a regexp match on the following:

=1;25;30;0;

, you'll get just about every set of performance data you have showing up in the results.

I found out onething if you have multiple CPU for e.g and it displays it under the same service i.e. the perf graphs are cpu=1 blah blah cpu=2.... then I can I only display the first the data set with this plugin ...oh well will have to re-think what I wanted to do...
