方法详细资料

registerExtendedMetrics

public void registerExtendedMetrics()

从类复制的说明: MetricRegistry

use other extension metrics,such as: jvm,vm,middleWares...

指定者:

registerExtendedMetrics 在类中 MetricRegistry

getRegistries

public Collection<Registry> getRegistries()

get all registry

返回:

registries, it is modifiable.

add

public void add(MetricRegistry registry)

Add a registry to the composite.

参数:

registry - metricRegistry

remove

public void remove(Registry registry)

Remove a registry from the composite.

参数:

registry - metricRegistry

clear

public void clear()

Remove all registries from the composite.

gauge

public <T extends Number> Gauge<T> gauge(Id id,
                                Gauge<T> gauge)

从接口复制的说明: Registry

Register a gauge instance

类型参数:

T - return old one;if this id first register gauge ,return null

参数:

id - metric id

gauge - gauge

返回:

gauge

removeMetric

public void removeMetric(Id id)

从接口复制的说明: Registry

Remove a metric by id.

参数:

id - metric id

info

public <I,Y extends Info<I>> Info info(Id id,
                              Y info)

从接口复制的说明: Registry

Register a info instance

参数:

id - metric id

info - an info instance

返回:

register

public void register(Metric metric)

从接口复制的说明: Registry

Add a custom metric to the registry.

caution: if the same id is already existed,then throw duplicate exception

参数:

metric - metric

counter

public Counter counter(Id id)

从接口复制的说明: Registry

Measures the rate of some activity. A counter is for continuously incrementing sources like the number of requests that are coming into a server.

参数:

id - metric id

返回:

counter

distributionSummary

public DistributionSummary distributionSummary(Id id)

从接口复制的说明: Registry

Measures the rate and variation in amount for some activity. For example, it could be used to get insight into the variation in response sizes for requests to a server.

参数:

id - metric id

返回:

DistributionSummary

timer

public Timer timer(Id id)

从接口复制的说明: Registry

Measures the rate and time taken for short running tasks.

参数:

id - metric id

返回:

timer

mixinMetric

public MixinMetric mixinMetric(Id id)

从接口复制的说明: Registry

Generate a mixinMetric

参数:

id - metric id

返回:

a mixinMetric instance

get

public <X extends Metric> X get(Id id)

从接口复制的说明: Registry

Returns the metric associated with a given id.

if reaching the max number,null will be returned too.

参数:

id - metric id

返回:

Instance of the metric or null if there is no match.

iterator

public Iterator<Metric> iterator()

从接口复制的说明: Registry

Iterator for traversing the set of metrics in the registry.
