public final class MetricNames extends Object
Metric names are also being duplicated by the metric tag
MetricTags.METRIC
.
The constants described here represent the various names metrics can take in Jet.

Edge
s of particular
Vertex
instances running on various Processor
s.
These in turn can be identified based on the
MetricTags.ORDINAL
, MetricTags.VERTEX
&
MetricTags.PROCESSOR
tags of the metric.public static final String RECEIVED_BATCHES
Edge
s of particular
Vertex
instances running on various Processor
s.
These in turn can be identified based on the
MetricTags.ORDINAL
, MetricTags.VERTEX
&
MetricTags.PROCESSOR
tags of the metric.public static final String QUEUE_SIZES
Vertex
on a particular Processor
. They both can be
identified based on the MetricTags.VERTEX
and
MetricTags.PROCESSOR
tags of the metric.public static final String QUEUE_CAPACITY
Vertex
on a particular Processor
. They both can be
identified based on the MetricTags.VERTEX
and
MetricTags.PROCESSOR
tags of the metric.public static final String EMITTED_COUNT
Edge
s of particular
Vertex
instances running on various Processor
s.
These in turn can be identified based on the
MetricTags.ORDINAL
, MetricTags.VERTEX
&
MetricTags.PROCESSOR
tags of the metric.
When the MetricTags.ORDINAL
tag contains the value "snapshot"
then the count contains the number of snapshots saved by the
Processor
.
public static final String TOP_OBSERVED_WM
Edge
s of a particular Vertex
(ie. the highest
watermark observed on all input queues of that Vertex
).
The Vertex
and the Processor
can be identified
based on the MetricTags.VERTEX
& MetricTags.PROCESSOR
tags of the metric.public static final String COALESCED_WM
Edge
of a certain Vertex
.
The Edge
and the Vertex
, together with the concrete
Processor
running them can be identified based on the
MetricTags.ORDINAL
, MetricTags.VERTEX
&
MetricTags.PROCESSOR
tags of the metric.public static final String LAST_FORWARDED_WM
Processor
,
which can be identified based on the MetricTags.PROCESSOR
tag.public static final String LAST_FORWARDED_WM_LATENCY
Processor
. The Processor
can be identified based on the MetricTags.PROCESSOR
tag.public static final String DISTRIBUTED_ITEMS_IN
Edge
s of particular Vertex
instances running on
various Processor
s. These in turn can be identified based
on the MetricTags.ORDINAL
, MetricTags.VERTEX
&
MetricTags.PROCESSOR
tags of the metric.public static final String DISTRIBUTED_BYTES_IN
Edge
s of particular Vertex
instances running on various Processor
s. These in turn can
be identified based on the MetricTags.ORDINAL
,
MetricTags.VERTEX
& MetricTags.PROCESSOR
tags of the metric.public static final String DISTRIBUTED_ITEMS_OUT
Edge
s of particular Vertex
instances running on
various Processor
s. These in turn can be identified based
on the MetricTags.ORDINAL
, MetricTags.VERTEX
&
MetricTags.PROCESSOR
tags of the metric.public static final String DISTRIBUTED_BYTES_OUT
Edge
s of particular Vertex
instances running on various Processor
s. These in turn can
be identified based on the MetricTags.ORDINAL
