public final class MetricTags
extends Object

Metric descriptors are formed from a comma separated list of tag_name=tag_value pairs. The constants defined here are the possible tag names that are used in Jet. See individual descriptions for the meaning of information carried by each tag.

Field Summary

Fields

Modifier and Type	Field and Description
static String	ADDRESS Network address of the cluster member sourcing the metric.
static String	COOPERATIVE_WORKER Index of the cooperative worker in a fixed worker pool sourcing the metric.
static String	DESTINATION_ADDRESS Destination member address for items sent to a distributed edge.
static String	EXECUTION Unique ID of a particular execution of a job (sourcing the metric), example value would be a numerical (long) ID encoded in a human readable form, like "2f7f-d88a-4669-6195", see Util.idToString(long) for details.
static String	JOB Unique ID of the job (sourcing the metric), example value would be a numerical (long) ID encoded in a human readable form, like "2f7f-d88a-4669-6195", see Util.idToString(long))} for details.
static String	MEMBER Unique ID of the cluster member sourcing the metric.
static String	MODULE Source system or module, value is always "jet".
static String	ORDINAL Index of the vertex input or output edges sourcing the metric.
static String	PROCESSOR Global index of the Processor sourcing the metric.
static String	PROCESSOR_TYPE Class name without package name of the Processor sourcing the metric (only for processor-specific metrics).
static String	SINK Boolean flag which is true if the Processor sourcing the metric is a DAG sink.
static String	SOURCE Boolean flag which is true if the Processor sourcing the metric is a DAG source.
static String	SOURCE_ADDRESS Source member address for items received from a distributed edge.
static String	UNIT Unit of metric value, for details see ProbeUnit.
static String	USER Boolean flag which is true if the metric is user-defined (as opposed to built-in).
static String	VERTEX DAG vertex name the of the metric.
