Query and command a Nagios install using the power of ruby (and lots of screen-scaping)! Do the usual gem install jig:

gem install nagiosharder

Now you have access to both a Ruby interface and a command line interface.

Here's some examples to get you started with the Ruby API:

require 'nagiosharder'
site ='http://path/to/nagios/cgi/directory', 'user', 'password', 'version')
# version defaults to 3

# get details back about a host's services
puts site.host_status('myhost')

# schedule a host to have services checks run again right now

# get details on all services
# or just services that have problems 
# (other valid symbols: :ok, :warning, :unknown, :critical, :pending, :all_problems)
# or make it sorted by  duration, descending
site.service_status(:all_problem, :sort_option => :duration, :sort_type => :desc
# (other sort_options: :host, :service, :status, :last_check, :duration, :attempts)
# (other sort_types: :asc, :desc)
# or get the details for a single service group
site.service_status(:all_problem, :group => "AWESOME")

# schedule a host to have services checks run again right now
site.schedule_service_check('myhost', 'myservice')

# schedule 20 minutes of downtime, starting now
site.schedule_host_downtime('myhost', :start_time =>, :end_time => + 20.minutes)

# schedule a flexible 20 minutes of downtime between now and 2 hours from now
site.schedule_host_downtime('myhost', :type => :flexible, :start_time =>, :end_time => + 2.hours, :hours => 0, :minutes => 20)

# acknowledge a down service
site.acknowledge_service('myhost', 'myservice', 'something bad happened')

# or unacknowledge
site.unacknowledge_service('myhost', 'myservice')

# disable notifications for a service:
site.disable_service_notifications('myhost', 'myservice')

# check if notifications are disabled:
site.service_notifications_disabled?('myhost', 'myservice')

# enable notifications for a service:
site.enable_service_notifications('myhost', 'myservice')

# disable notifications, and wait for nagios to process it:
site.disable_service_notifications('myhost', 'myservice')
until site.service_notifications_disabled?('myhost', 'myservice')
  sleep 3

Then there's the command line. Start with –help

nagiosharder --help

This will show you how you configure nagiosharder enough to talk to your nagios. You need at least a username, password, and nagios url. These can alternatively be in a config file. For example:

nagiosharder --config /path/to/yaml

This will display all available commands.

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
