Package io.micrometer.core.instrument.observation

Class DefaultMeterObservationHandler

java.lang.Object
io.micrometer.core.instrument.observation.DefaultMeterObservationHandler
All Implemented Interfaces:
MeterObservationHandler<io.micrometer.observation.Observation.Context>, io.micrometer.observation.ObservationHandler<io.micrometer.observation.Observation.Context>
public class DefaultMeterObservationHandler extends Object implements MeterObservationHandler<io.micrometer.observation.Observation.Context>
Handler for Timer.Sample and Counter. WARNING: Since the LongTaskTimer needs to be created in the onStart method, it can only contain tags that are available by that time. This means that if you add a lowCardinalityKeyValue after calling start on the Observation, that KeyValue will not be translated as a Tag on the LongTaskTimer. Likewise, since the KeyValuesProvider is evaluated in the stop method of the Observation (after start), those KeyValue instances will not be used for the LongTaskTimer.
Since:
1.10.0
