nagios-rb
A compact framework for writing Nagios plugins.
Quick Start
Subclass Nagios::Plugin
, and define three methods:
measure - returns the measured value, and optionally sets
@stats
for later usage.critical - for any given n, returns whether in critical state.
warning - for any given n, returns whether in warning state.
Example Plugin
In this trivial example, the plugin always measures 2, which is below both the warning and critical thresholds.
require 'nagios'
class FooPlugin < Nagios::Plugin
def critical(n)
n > 5
end
def warning(n)
n > 3
end
def measure
2
end
end
FooPlugin.new.run!
Future Work
Lots.
