Work Description: ryan-williams commented on pull request #7934: [DO NOT
MERGE] [BEAM-4775] add GetJobMetrics RPC
URL: https://github.com/apache/beam/pull/7934
- Send metrics over the job API
- new job API RPC depends on `MonitoringInfo` protos from the fn api
- per discussion with @robertwb, I'm going to move `MonitoringInfo` into
`model/pipeline`, to avoid introducing a [job API] → [fn API] dep
- as such, **this PR shouldn't be merged as-is**; that proto move should
happen first, but I wanted to get this out for Jenkins and first review pass
- add Python and Java SDK support for portable metrics over the job API
- portable python flink wordcount outputs the integer `empty_lines` metric!
- Flink attempted counter PVR cases are now enabled
R: @robertwb @ajamato
CC: @mxm since I reworked the Flink metrics a bit in particular

> JobService should support returning metrics

> Key: BEAM-4775
> URL: https://issues.apache.org/jira/browse/BEAM-4775
> Project: Beam
> Issue Type: Bug
> Components: beam-model
> Reporter: Eugene Kirpichov
> Assignee: Ryan Williams
> Priority: Major
> Labels: triaged
> Time Spent: 19h
> Remaining Estimate: 0h
>
> Design doc: [https://s.apache.org/get-metrics-api].
> h1. Relevant PRs in flight:
> h2. Approved / Ready to merge:
> * [#7890|https://github.com/apache/beam/pull/7890]: consolidate MetricResult
> implementations
> * [#7883|https://github.com/apache/beam/pull/7883]: Add
> MetricQueryResults.allMetrics() helper
> h2. Ready for Review:
> * #[7915|https://github.com/apache/beam/pull/7915]: use MonitoringInfo data
> model in Java SDK metrics
> ** Depends on [#7867|https://github.com/apache/beam/pull/7867]
> ** Both of these require adding a {{sdks/java/core}} dependency on the
> {{model/fn-execution}} protos module.
> *** I want to discuss whether that's ok.
> *** It may not be totally necessary; see discussion on
> #[7915|https://github.com/apache/beam/pull/7915].
> h2. Iterating / Discussing:
> * [#7868|https://github.com/apache/beam/pull/7868]: MonitoringInfo URN tweaks
> h2. Merged
> * [#7866|https://github.com/apache/beam/pull/7866]: move function helpers
> from fn-harness to sdks/java/core
> h2. Closed
> * [#7876|https://github.com/apache/beam/pull/7876]: Clean up metric protos;
> support integer distributions, gauges
> h1. Likely pieces still to come:
> I have these implemented in a branch, but need to pull them out into
> manageable PRs:
> * adding the job-API metrics RPC
> * python support
> h1. Previous Description:
> [https://github.com/apache/beam/blob/master/model/job-management/src/main/proto/beam_job_api.proto]
> currently doesn't appear to have a way for JobService to return metrics to a
> user, even though
> [https://github.com/apache/beam/blob/master/model/fn-execution/src/main/proto/beam_fn_api.proto]
> includes support for reporting SDK metrics to the runner harness.
> Metrics are apparently necessary to run any ValidatesRunner tests because
> PAssert needs to validate that the assertions succeeded. However, this
> statement should be double-checked: perhaps it's possible to somehow work
> with PAssert without metrics support.
