A Sampler is used to capture meaningful metrics in a background thread periodically. They will be invoked about once a minute, each time the agent sends data to New Relic‘s servers.

Samplers can be added to New Relic by subclassing NewRelic::Agent::Sampler. Instances are created when the agent is enabled and installed. Subclasses are registered for instantiation automatically.
