MetricRegistryImpl

public MetricRegistryImpl(MetricRegistryConfiguration config)

MetricRegistryImpl

public MetricRegistryImpl(MetricRegistryConfiguration config,
                          Collection<ReporterSetup> reporterConfigurations)

Creates a new MetricRegistry and starts the configured reporter.

方法详细资料

startQueryService

public void startQueryService(org.apache.flink.runtime.rpc.RpcService rpcService,
                              ResourceID resourceID)

Initializes the MetricQueryService.

参数:

rpcService - RpcService to create the MetricQueryService on

resourceID - resource ID used to disambiguate the actor name

getMetricQueryServiceRpcService

@Nullable
public org.apache.flink.runtime.rpc.RpcService getMetricQueryServiceRpcService()

Returns the rpc service that the MetricQueryService runs in.

返回:

rpc service of hte MetricQueryService

getMetricQueryServiceGatewayRpcAddress

@Nullable
public String getMetricQueryServiceGatewayRpcAddress()

Returns the address under which the MetricQueryService is reachable.

指定者:

getMetricQueryServiceGatewayRpcAddress 在接口中 MetricRegistry

返回:

address of the metric query service

getDelimiter

public char getDelimiter()

从接口复制的说明: MetricRegistry

Returns the global delimiter.

指定者:

getDelimiter 在接口中 MetricRegistry

返回:

global delimiter

getNumberReporters

public int getNumberReporters()

从接口复制的说明: MetricRegistry

Returns the number of registered reporters.

指定者:

getNumberReporters 在接口中 MetricRegistry

getReporters

@VisibleForTesting
public List<org.apache.flink.metrics.reporter.MetricReporter> getReporters()

isShutdown

public boolean isShutdown()

Returns whether this registry has been shutdown.

返回:

true, if this registry was shutdown, otherwise false

shutdown

public CompletableFuture<Void> shutdown()

Shuts down this registry and the associated MetricReporter.

NOTE: This operation is asynchronous and returns a future which is completed once the shutdown operation has been completed.

返回:

Future which is completed once the MetricRegistryImpl is shut down.

getScopeFormats

public ScopeFormats getScopeFormats()

从接口复制的说明: MetricRegistry

Returns the scope formats.

指定者:

getScopeFormats 在接口中 MetricRegistry

返回:

scope formats

register

public void register(org.apache.flink.metrics.Metric metric,
                     String metricName,
                     AbstractMetricGroup group)

从接口复制的说明: MetricRegistry

Registers a new Metric with this registry.

指定者:

register 在接口中 MetricRegistry

参数:

metric - the metric that was added

metricName - the name of the metric

group - the group that contains the metric

unregister

public void unregister(org.apache.flink.metrics.Metric metric,
                       String metricName,
                       AbstractMetricGroup group)

从接口复制的说明: MetricRegistry

Un-registers the given Metric with this registry.

指定者:

unregister 在接口中 MetricRegistry

参数:

metric - the metric that should be removed

metricName - the name of the metric

group - the group that contains the metric
