Method Detail

getSolrMetricsContext

public SolrMetricsContext getSolrMetricsContext()

Description copied from interface: SolrMetricProducer

Implementing classes should override this method to provide the context obtained in SolrMetricProducer.initializeMetrics(SolrMetricsContext, String) to ensure proper cleanup of metrics at the end of the life-cycle of this component.

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.

scope - component scope
