initializeMetrics

public void initializeMetrics(SolrMetricManager manager,
                              String registry,
                              String tag,

Description copied from interface: SolrMetricProducer

Initializes metrics specific to this producer.

Note: for back-compatibility this method by default calls SolrMetricProducer.initializeMetrics(SolrMetricManager, String, String).

Specified by:

initializeMetrics in interface SolrMetricProducer

Parameters:

manager - an instance of SolrMetricManager

registry - registry name where metrics are registered

tag - symbolic tag that represents a group of related instances that have the same life-cycle. Parent component can use the tag when calling SolrMetricManager.unregisterGauges(String, String) to unregister metrics created by this instance of the producer.

scope - scope of the metrics (eg. handler name) to separate metrics of instances of the same component executing in different contexts
