org.apache.flink.runtime.metrics.groups.AbstractMetricGroup<P>

org.apache.flink.runtime.metrics.groups.ComponentMetricGroup<JobManagerMetricGroup>

org.apache.flink.runtime.metrics.groups.JobManagerMetricGroup

所有已实现的接口:

org.apache.flink.metrics.MetricGroup, LocallyCleanableResource

直接已知子类:

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

方法详细资料

createJobManagerMetricGroup

public static JobManagerMetricGroup createJobManagerMetricGroup(MetricRegistry metricRegistry,
                                                                String hostname)

hostname

public String hostname()

createQueryServiceMetricInfo

protected QueryScopeInfo.JobManagerQueryScopeInfo createQueryServiceMetricInfo(org.apache.flink.metrics.CharacterFilter filter)

从类复制的说明: AbstractMetricGroup

Creates the metric query service scope for this group.

指定者:

createQueryServiceMetricInfo 在类中 AbstractMetricGroup<JobManagerMetricGroup>

参数:

filter - character filter

返回:

query service scope

addJob

public JobManagerJobMetricGroup addJob(org.apache.flink.api.common.JobID jobId,
                                       String jobName)

localCleanupAsync

public CompletableFuture<Void> localCleanupAsync(org.apache.flink.api.common.JobID jobId,
                                                 Executor ignoredExecutor)

从接口复制的说明: 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.

指定者:

localCleanupAsync 在接口中 LocallyCleanableResource

参数:

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

ignoredExecutor - The fallback executor for IO-heavy operations.

返回:

The cleanup result future.

numRegisteredJobMetricGroups

public int numRegisteredJobMetricGroups()

putVariables

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

从类复制的说明: AbstractMetricGroup

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

覆盖:

putVariables 在类中 AbstractMetricGroup<JobManagerMetricGroup>

参数:

variables - map to enter variables and their values into

subComponents

protected Iterable<? extends ComponentMetricGroup> subComponents()

从类复制的说明: ComponentMetricGroup

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

指定者:

subComponents 在类中 ComponentMetricGroup<JobManagerMetricGroup>

返回:

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

getGroupName

protected String getGroupName(org.apache.flink.metrics.CharacterFilter filter)

从类复制的说明: AbstractMetricGroup

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

指定者:

getGroupName 在类中 AbstractMetricGroup<JobManagerMetricGroup>

参数:

filter - character filter which is applied to the name

返回:

logical name for this group
