org.apache.hadoop.hbase.metrics.MetricRegistryInfo

@InterfaceAudience.Private
public class MetricRegistryInfo
extends Object

方法详细资料

getMetricsContext

public String getMetricsContext()

Get the metrics context. For hadoop metrics2 system this is usually an all lowercased string. eg. regionserver, master, thriftserver

返回:

The string context used to register this source to hadoop's metrics2 system.

getMetricsDescription

public String getMetricsDescription()

Get the description of what this source exposes.

getMetricsJmxContext

public String getMetricsJmxContext()

Get the name of the context in JMX that this source will be exposed through. This is in ObjectName format. With the default context being Hadoop -> HBase

getMetricsName

public String getMetricsName()

Get the name of the metrics that are being exported by this source. Eg. IPC, GC, WAL

isExistingSource

public boolean isExistingSource()

Returns whether or not this MetricRegistry is for an existing BaseSource

返回:

true if this MetricRegistry is for an existing BaseSource.

equals

public boolean equals(Object obj)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object
