org.apache.seatunnel.api.common.metrics.Measurement

所有已实现的接口:

Serializable

public final class Measurement
extends Object
implements Serializable

Immutable data class containing information about one metric measurement, consisting of:

• metric value
• metric timestamp, generated when the metric was gathered
• metric descriptor (set of tag name-value pairs)

A metrics descriptor can be thought of as a set of attributes associated with a particular metric, metric which in turn is defined by its name (for a full list of metric names provided see MetricNames). The attributes are specified as tags that have names and values (for a full list of tag names see MetricTags). An example descriptor would have a collection of tags/attributes like this: job=jobId, pipeline=pipelineId, unit=count, metric=SourceReceivedCount, ...

of

public static Measurement of(String metric,
                             Object value,
                             long timestamp,
                             Map<String,String> tags)

Builds a Measurement instance based on timestamp, value and the metric descriptor in map form.

value

public Object value()

Returns the value associated with this Measurement.

timestamp

public long timestamp()

Returns the timestamps associated with this Measurement, the moment when the value was gathered.

metric

public String metric()

Returns the name of the metric. For a list of different metrics see MetricNames.

tag

public String tag(String name)

Returns the value associated with a specific tag, based on the metric description of this particular Measurement. For a list of possible tag names see MetricTags.
