JIRA: Jira server ASF JIRA serverId 5aa69414-a9e9-3523-82ec-879b028fb15b key FLINK-14144
Released: <Flink Version>
Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).
Motivation
There is a metric tab in each taskmanager page, but there is no metric data in the job manager, it would be better for users to monitor the cluster with job manager metrics.
Proposed Changes
Add a metric page in job manager, and display the job manager metrics
...
- add JobManager metrics in MetricStore
- show JobManager memory and Garbage collectors
- after FLINK-9741 finished, show it according to flip-6
- url: /jobmanager/metrics/info
- response:
{ "type" : "object", "id" : "urn:jsonschema:org:apache:flink:runtime:rest:messages:cluster:JobManagerMetricsInfo", "properties" : { "heapUsed" : { "type" : "integer" }, "heapCommitted" : { "type" : "integer" }, "heapMax" : { "type" : "integer" }, "nonHeapUsed" : { "type" : "integer" }, "nonHeapCommitted" : { "type" : "integer" }, "nonHeapMax" : { "type" : "integer" }, "directCount" : { "type" : "integer" }, "directUsed" : { "type" : "integer" }, "directMax" : { "type" : "integer" }, "mappedCount" : { "type" : "integer" }, "mappedUsed" : { "type" : "integer" }, "mappedMax" : { "type" : "integer" }, "garbageCollectors" : { "type" : "array", "items" : { "type" : "object", "id" : "urn:jsonschema:org:apache:flink:runtime:rest:messages:cluster:JobManagerMetricsInfo:GarbageCollectorInfo", "properties" : { "name" : { "type" : "string" }, "count" : { "type" : "integer" }, "time" : { "type" : "integer" } } } } } } |
