Qs Bao reassigned OOZIE-3305:
-----------------------------
Attachment: OOZIE-3305-001.patch
Affects Version/s: (was: 4.2.0)
trunk
Assignee: Qs Bao
[~andras.piros] [~asalamon74] I'd like to work on this.
Patch is submitting, in this patch:
* Introduced two prometheus client packages {{simpleclient_dropwizard}} and
{{simpleclient_common}}, for convert dropwizard metrics to prometheus format
metrics.
* Added a new HTTP endpoint {{/v2/admin/prometheus}} to expose prometheus
metrics.
Worth noting that:
* The new endpoint is always enabled, considering that prometheus metrics
exposed passively via periodic pull from prometheus server.
* The new endpoint have not supported in Oozie CLI, and have not documented in
API doc.
* The new endpoint's response type is text instend of json, but as I know all
existing oozie servlets extend from `JsonRestServlet`.
Looking forward to hearing you suggesions.
