Method Detail

getResourceMethodExecutionStatistics

public ExecutionStatistics getResourceMethodExecutionStatistics()

Description copied from interface: ResourceStatistics

Get execution statistics that contain measurements of times only for execution of resource methods. Durations average time, minimum time and maximum time measure only time of execution of resource methods code. It does not involve other request processing phases.

Specified by:

getResourceMethodExecutionStatistics in interface ResourceStatistics

Returns:

Execution statistics of all resource method in this resource.

getRequestExecutionStatistics

public ExecutionStatistics getRequestExecutionStatistics()

Description copied from interface: ResourceStatistics

Get execution statistics that contain measurements of times for whole processing from time when request comes into the Jersey application until the response is written to the underlying IO container. The statistics involves only requests that were matched to resource methods defined in ResourceStatistics.getResourceMethodStatistics().

Specified by:

getRequestExecutionStatistics in interface ResourceStatistics

Returns:

Execution statistics of entire request processing for all resource method from this resource.

getResourceMethodStatistics

public java.util.Map<ResourceMethod,ResourceMethodStatistics> getResourceMethodStatistics()

Description copied from interface: ResourceStatistics

Return the statistics for resource method. Keys of returned map are resource methods available in the resource and values are execution statistics of these resource methods.

Specified by:

getResourceMethodStatistics in interface ResourceStatistics

Returns:

Map with resource method keys and corresponding resource method statistics.

snapshot

public ResourceStatistics snapshot()

Description copied from interface: ResourceStatistics

Get the immutable and consistent snapshot of the monitoring statistics. Working with snapshots might have negative performance impact as snapshot must be created but ensures consistency of data over time. However, the usage of snapshot is encouraged to avoid working with inconsistent data. Not all statistics must be updated in the same time on mutable version of statistics.

Specified by:

snapshot in interface ResourceStatistics

Returns:

Snapshot of resource statistics.
