      Work Description: ryan-williams commented on issue #7823: [DO NOT MERGE] 
[BEAM-4775] Second take on portable metrics over the job-server API
URL: https://github.com/apache/beam/pull/7823#issuecomment-465348737
 
 
   > I'm not sure if you want me to review this one or not. This PR is a bit 
massive.
   
   Yea, there are probably 4 chunks I will still pull out of this into separate 
PRs, that are hopefully more manageable:
   - consolidating MetricResult implementations
     - already out at #7890, though I need to fix a couple tests
     - I haven't had a chance to factor those changes out of this PR yet
   - fully supporting MonitoringInfo data types ({URN, labels}) inside 
`MetricKey` (comprised of `MetricName`,`MetricLabels`)
   - adding the job-API metrics RPC
   - python support
   
   In the meantime, [this link will show all the changes that still live only 
in this 
PR](https://github.com/ryan-williams/beam/compare/octo...ryan-williams:mk); 
this PR's main view still displays all the changes it is rebased on top of.
   
   > Is this the one that introduces the new layer to extract the new 
MonitoringInfo metrics over an RPC?
   https://s.apache.org/get-metrics-api
   
   Yea, that is in here! Swimming to the surface…

> [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.
