 # Hallmonitor
 
 Hallmonitor is a simple event monitoring framework for Ruby.  It allows programs to define and emit events. These events can then be sent on to various back ends to be counted, monitored, etc.
 
-Hallmonitor includes support for publishing events to a Statsd instance if the `statsd-ruby` gem is installed.  See https://github.com/reinh/statsd for details.
-It also includes support for outputting events to InfluxDB if the 'influxdb' gem is installed.
+Hallmonitor includes support for the following outputters:
 
+- [Statsd](https://github.com/reinh/statsd) - Requires the `statsd` gem to be installed
+- [InfluxDB](https://github.com/influxdata/influxdb-ruby) - Requires the `influxdb` gem to be installed
+- [Datadog](https://github.com/DataDog/dogstatsd-ruby) - Requires the `dogstatsd-ruby` gem to be installed
+- IOOutputter - Simple outputter that outputs to an IO object
+- [NewRelic](https://github.com/newrelic/rpm) - Requires the `newrelic_rpm` gem to be installed
+

 ## Setup
 Before you can use Hallmonitor you have to do a tiny bit of configuration in the form of adding outputters.
 
 ```ruby
 # Add an outputter to STDOUT
+require 'hallmonitor/outputters/iooutputter.rb'
 Hallmonitor.add_outputter Hallmonitor::Outputters::IOOutputter.new("STDOUT", STDOUT)
 
 # Add an outputter to StatsD
+require 'hallmonitor/outputters/statsd_outputter'
 Hallmonitor.add_outputter Hallmonitor::Outputters::StatsdOutputter.new("example", "localhost")
+
+# Add an outputter to Datadog
+require 'hallmonitor/outputters/datadog
+datadog = Datadog::Statsd.new
+Hallmonitor.add_outputter Hallmonitor::Outputters::Datadog.new(datadog)
 ```
 
-The `StatsdOutputter` is only available if you've installed the `statsd-ruby` gem.  If it's not available, StatsdOutputter's intitialize method will raise a RuntimeError

 ## Configuration
 Right now there's only one configuration option and here's how you can set it:
 
 ```ruby

 * Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
 * Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
