Modifier and Type	Method	Description
`SolrMetricsContext`	`getSolrMetricsContext()`	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.
`void`	`initializeMetrics(SolrMetricsContext parentContext, String scope)`	Initialize metrics specific to this producer.

    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
