Nagios Output

A simple wrapper for creating nagios consumable output - including exit codes.

Installation

Add this line to your application's Gemfile:

gem 'nagios_output'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nagios_output

Usage

There are 3 different ways to access the 4 nagios output methods. Those methods are ok, warning, critical and unknown, they have the following spective exit codes 0, 1, 2 and 3.

Class Method

require 'nagios_output'

n = NagiosOutput.new
n.ok('Everything is ok (Class))')
n.warning('Everything is ok-ish (Class)')
n.critical('Everything is cirtial (Class)')
n.unknown('Everything is erm - I don\'t know (Class)')

Static Method

require 'nagios_output'

NagiosOutputStatic.ok('Everything is ok (Static)')
NagiosOutputStatic.warning('Everything is ok-ish (Static)')
NagiosOutputStatic.critical('Everything is cirtial (Static)')
NagiosOutputStatic.unknown('Everything is erm - I don\'t know (Static)')

Direct Method

require 'nagios_output'

ok('Everything is ok (Direct)')
warning('Everything is ok-ish (Direct)')
critical('Everything is cirtial (Direct)')
unknown('Everything is erm - I don\'t know (Direct)')

It is worth noting that the above examples will not function as you might first expect if you cut and paste them and run them. They will all show the ok() message then stop. Remember each function also makes a call to exit().

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Testing

For local testing make sure that you run bundle exec rspec spec and then rake install to install the gem locally.
