How to create graphs on services?

[morganmiskell]

Hi, I've done some light google searching and I've not found anything. I have a bunch of services that are monitoring numeric responses that I'd like to generate graphs in the nagios interface. For example, the disk space monitor program automatically generates utilization graphs. How would I create the same capability within a custom hand written monitor?

You could follow the Nagios Plugins Guidelines, in order to write your custom plugin in a way that it would return perfdata. Learn more about the performance data required formatting here:
