> h1. Relevant PRs in flight:

> * [#7938|https://github.com/apache/beam/pull/7938]: move MonitoringInfo
> protos to model/pipeline module
> * [#7867|https://github.com/apache/beam/pull/7867]: key MetricResult by a

> h2. Ready for Review:
> * [#7934|https://github.com/apache/beam/pull/7934]: add GetJobMetrics RPC,
> Java+Python SDK support for it
> *
> ** will need to be rebased on top of
> [#7938|https://github.com/apache/beam/pull/7938]
> * #[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]
> ** will be need to be rebased on top of
> [#7938|https://github.com/apache/beam/pull/7938]
> ** 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
> * [#7883|https://github.com/apache/beam/pull/7883]: Add
> MetricQueryResults.allMetrics() helper
> * [#7866|https://github.com/apache/beam/pull/7866]: move function helpers
> from fn-harness to sdks/java/core
> * [#7890|https://github.com/apache/beam/pull/7890]: consolidate MetricResult
> implementations
> h2. Closed
> * [#7876|https://github.com/apache/beam/pull/7876]: Clean up metric protos;
> support integer distributions, gauges
> h1. Likely pieces still to come:
> Per recent discussion with [~robertwb], I'm going to move the MonitoringInfo
> protos into the {{model/pipeline}} module, which the Job API, Fn API, and
> sdks/java/core all depend on already, as it's a good/central place for them.
> 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.
