initializeMetrics

public void initializeMetrics(SolrMetricsContext parentContext,
 io.opentelemetry.api.common.Attributes attributes)

Description copied from interface: SolrMetricProducer

Implementation should initialize all metrics to a SolrMetricsContext Registry/MeterProvider with Attributes as the common set of attributes that will be attached to every metric that is initialized for that class/component

Specified by:

initializeMetrics in interface SolrMetricProducer

Overrides:

initializeMetrics in class SearchHandler

Parameters:

parentContext - The registry that the component will initialize metrics to

attributes - Base set of attributes that will be bound to all metrics for that component

inform

public void inform(SolrCore core)

Description copied from class: SearchHandler

Initialize the components based on name. Note, if using INIT_FIRST_COMPONENTS or INIT_LAST_COMPONENTS, then the DebugComponent will always occur last. If this is not desired, then one must explicitly declare all components using the INIT_COMPONENTS syntax.

Specified by:

inform in interface SolrCoreAware

Overrides:

inform in class SearchHandler

handleRequestBody

public void handleRequestBody(SolrQueryRequest req,
 SolrQueryResponse rsp)
                       throws Exception

Overrides:

handleRequestBody in class SearchHandler

Throws:

Exception
