Direct Known Subclasses:

UnregisteredMetricGroups.UnregisteredJobManagerMetricGroup

public class JobManagerMetricGroup
extends ComponentMetricGroup<JobManagerMetricGroup>
implements LocallyCleanableResource

Special MetricGroup representing a JobManager.

Contains extra logic for adding jobs with tasks, and removing jobs when they do not contain tasks any more

Method Detail

createJobManagerMetricGroup

public static JobManagerMetricGroup createJobManagerMetricGroup(MetricRegistry metricRegistry,
                                                                String hostname)

hostname

public String hostname()

createQueryServiceMetricInfo

protected QueryScopeInfo.JobManagerQueryScopeInfo createQueryServiceMetricInfo(CharacterFilter filter)

Description copied from class: AbstractMetricGroup

Creates the metric query service scope for this group.

Specified by:

createQueryServiceMetricInfo in class AbstractMetricGroup<JobManagerMetricGroup>

Parameters:

filter - character filter

Returns:

query service scope

addJob

public JobManagerJobMetricGroup addJob(JobID jobId,
                                       String jobName)

localCleanupAsync

public CompletableFuture<Void> localCleanupAsync(JobID jobId,
                                                 Executor ignoredExecutor)

Description copied from interface: LocallyCleanableResource

localCleanupAsync is expected to be called from the main thread. Heavy IO tasks should be outsourced into the passed cleanupExecutor. Thread-safety must be ensured.

Specified by:

localCleanupAsync in interface LocallyCleanableResource

Parameters:

jobId - The JobID of the job for which the local data should be cleaned up.

ignoredExecutor - The fallback executor for IO-heavy operations.

Returns:

The cleanup result future.

numRegisteredJobMetricGroups

public int numRegisteredJobMetricGroups()

putVariables

protected void putVariables(Map<String,String> variables)

Description copied from class: AbstractMetricGroup

Enters all variables specific to this AbstractMetricGroup and their associated values into the map.

Overrides:

putVariables in class AbstractMetricGroup<JobManagerMetricGroup>

Parameters:

variables - map to enter variables and their values into

subComponents

protected Iterable<? extends ComponentMetricGroup> subComponents()

Description copied from class: ComponentMetricGroup

Gets all component metric groups that are contained in this component metric group.

Specified by:

subComponents in class ComponentMetricGroup<JobManagerMetricGroup>

Returns:

All component metric groups that are contained in this component metric group.

getGroupName

protected String getGroupName(CharacterFilter filter)

Description copied from class: AbstractMetricGroup

Returns the name for this group, meaning what kind of entity it represents, for example "taskmanager".

Specified by:

getGroupName in class AbstractMetricGroup<JobManagerMetricGroup>

Parameters:

filter - character filter which is applied to the name

Returns:

logical name for this group
