Examples of RichGaugeRepository

org.springframework.xd.analytics.metrics.core.RichGaugeRepository
A service for managing RichGauge instances. The setValue method updates the current value of the gauge as well as incrementing the internal counter and updating the max, min and average values. It also provides a 'getOrCreate' method that will return an existing gauge given the name or create a new gauge set to zero. @author Luke Taylor
