getCategory

public SolrInfoBean.Category getCategory()

Description copied from interface: SolrInfoBean

getCategory in interface SolrInfoBean

getMetricNames

public Set<String> getMetricNames()

Description copied from interface: SolrInfoBean

Modifiable set of metric names that this component reports (default is null, which means none). If not null then this set is used by SolrInfoBean.registerMetricName(String) to capture what metrics names are reported from this component.

NOTE: this set has to allow iteration under modifications.

Specified by:

getMetricNames in interface SolrInfoBean

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
