You can install those plugins wherever you want.
On my Debian systems, Munin plugins are stored in /usr/share/munin/plugins.
I've installed those in my home directory and it works well.
At the top of the plugins, the load path is altered to search for helper files in the same directory as the plugin, and in the standard plugin directory (if the MUNIN_LIBDIR environment variable is set).
A graph with a line for the total number of pending jobs, and a line for each queue.
A graph with the total number of workers and the number of active (busy) workers.
There are 2 levels :
- warning = 1.5 x workers
- critical = 3 x workers
For the moment, those thresholds are not configurable in plugin settings.
This file has the same purpose as plugin.sh but for Ruby scripts.
It provides a simple stats method, that returns a nested hash from Resque::Server web app.
