Method Detail

getOverridenComponentName

protected String getOverridenComponentName(Resource resource)

checkPropertyIds

public Set<String> checkPropertyIds(Set<String> propertyIds)

Support properties with aggregate functions and metrics padding method.

Specified by:

checkPropertyIds in interface PropertyProvider

Overrides:

checkPropertyIds in class BaseProvider

Returns:

a subset of the given property id set containing any property ids not supported by this resource provider. An empty return set indicates that all of the given property ids are supported.

populateResourcesWithProperties

public Set<Resource> populateResourcesWithProperties(Set<Resource> resources,
                                                     Request request,

                                              throws SystemException

Description copied from class: MetricsPropertyProvider

Delegate implementation of populating resources to concrete providers.

Specified by:

populateResourcesWithProperties in class MetricsPropertyProvider

Parameters:

resources - @Resource

request - @Request

propertyIds - Set of ids

Returns:

@Set of resources

Throws:

SystemException

getComponentMetrics

public Map<String,Map<String,PropertyInfo>> getComponentMetrics()

Return a propertyInfoMap for all metrics. Handles special case for METRICS_COLLECTOR metrics by returning HBase metrics.

Overrides:

getComponentMetrics in class AbstractPropertyProvider

Returns:

the map of metric / property info.
