getSolrMetricsContext

public SolrMetricsContext getSolrMetricsContext()

Description copied from interface: SolrMetricProducer

Implementations should return the context used in SolrMetricProducer.initializeMetrics(SolrMetricsContext, String) to ensure proper cleanup of metrics at the end of the life-cycle of this component. This should be the child context if one was created, or null if the parent context was used.

Specified by:

getSolrMetricsContext in interface SolrMetricProducer

initializeMetrics

public void initializeMetrics(SolrMetricsContext parentContext,
 String scope)

Description copied from interface: SolrMetricProducer

Initialize metrics specific to this producer.

Specified by:

initializeMetrics in interface SolrMetricProducer

Parameters:

parentContext - parent metrics context. If this component has the same life-cycle as the parent it can simply use the parent context, otherwise it should obtain a child context using SolrMetricsContext.getChildContext(Object) passing this as the child object.

scope - component scope
