Nagios plugin to poll Graphite

What does it do? How does it work? How do I run it?

This is a Nagios plugin. Install it and configure a service check in Nagios and it will run whenever Nagios calls it and will report back on the status of whatever it's monitoring.

It has one required parameter -u which tells it the Graphite URL to monitor, for example:

http://server/render?target=stats.auctionStart&from=-1minutes&rawData=true`

When run, it will query that URL, calculate the average (or another function) of the recieved values, compare the average to the warning/critical thresholds, and return the value to Nagios as performance data.

See Graphite's URL API documentation on how to generate the URL parameter.

Usage
