Interface Metric

All Known Subinterfaces:

DoubleGauge, LongGauge

public interface Metric

A Metric is a 'quantitative measure' of something for example the number of operations pending, number of operations per second being executed etc. Each metric is uniquely identified using a name. See getName(). A metric gets its content from a probe. An probe can be one of the following:

1. a method with the Probe annotation
2. a field with the Probe annotation
3. a LongProbeFunction
4. a DoubleProbeFunction

If the Metric is obtained before a probe is registered, the Metric is without probe. As long as no probe is available, every time the metrics needs a value, it will look up the probe in the MetricsRegistry.
