== DESCRIPTION:
This allows you to easily write Nagios plugins in Ruby.
==== Example
#!/usr/bin/env ruby
require 'rubygems'
require 'nagios-plugin'
require 'time'
class MyNagiosCheck < Nagios::Plugin
# What should run when check is run
def run
# Get more options via arguments using the OptParse object.
# -w and -c for warning and critical thresholds are already included
@opts.on('-H', '--host HOST', 'Proxy server to check') do |h|
@proxy_host = h
end
# Init the argument parser
parse_argv
# Begin the check
begin
# Record the second when the check started to run
started_at=Time.now
# Run the commands you actually need for your check
some_ruby_code_to_run
# Calculate the run time
run_time = Time.now - started_at
# Add Performance data
add_perfdata(:field => "run time", :data => run_time, :critical => @critical, :warning => @warning, :uom => 'secs')
# Check the values against the thresholds
if run_time > @critical.to_f
critical("Took more than #{@critical}")
elsif run_time > @warning.to_f
warning("Took more than #{@warning}")
else
ok("Yay!")
end
# When the code has failed
rescue
critical("Check Failed!")
end
end
end
# Initialize and run the check!
@my_nagios_check = MyNagiosCheck.new(:shortname => 'my_nagios_check')
@my_nagios_check.run
