NOTE :The collector is being deprecated. The recommended way of getting metrics out of your Cloud Foundry environment is to use a firehose nozzle.
The collector will discover the various components on the message bus and
query their /healthz and /varz interfaces.
The metric data collected is published to collector plugins. See the lib/historian folder for available plugins such as OpenTSDB, AWS CloudWatch and DataDog. Plugins are extensible to publish data to other systems.
Additional metrics can be written by providing
Handler plugins. See lib/collector/handler.rb and
lib/collector/handlers/dea.rb for an example.
