# CheckGraphite

# A simple framework for writing nagios checks based on Graphite data.

# Usage
# -----
#
#    $ cat /tmp/page-queue.coffee
#    CheckGraphite = require('check-graphite')
#
#    class PageQueue extends CheckGraphite
#      options:
#        from: "-20s"
#        until: "-10s"
#        targets:
#          'resque.queue.page':
#            alias: 'value'
#
#      output: (value) ->
#        message = "#{value} jobs in the page queue"
#        if value > 20
#          @critical message
#        else if value > 10
#          @warning message
#        else
#          @ok message
#
#      module.exports = @
#
#    $ ./bin/check_graphite /tmp/page-queue.coffee
#    OK: 0 jobs in the page queue
#
# CheckGraphite expects that the options hash be provided in a format acceptable
# to Graphite.coffee. By default, the first data point in the result set with
# the alias 'value' is passed to the output() method. Subclasses may override
# the represent() method to perform the conversion from raw to massaged data
# differently.
