Work Description: lukecwik commented on issue #8913: [BEAM-7605] Allow
user-code to read counters from the dataflow worker
URL: https://github.com/apache/beam/pull/8913#issuecomment-504115136
I can understand why you would want this. There would be two previous
contributors that work in this space more then I that would be valuable to get
their input form.
@echauchot who was the designer of the MetricsPusher and @ajamato who has
done a lot metrics related work with Dataflow.
I would like to give some useful context pointers/notes in the meantime:
* you should really integrate and use MetricsPusher:
https://github.com/apache/beam/blob/master/runners/core-java/src/main/java/org/apache/beam/runners/core/metrics/MetricsPusher.java
* Jira issues BEAM-3310 and specifically BEAM-3926 for Dataflow
* the original metrics pusher thread (includes design docs)
https://lists.apache.org/thread.html/01a80d62f2df6b84bfa41f05e15fda900178f882877c294fed8be91e@%3Cdev.beam.apache.org%3E
* and it would be good to integrate this in both batch and streaming
dataflow workers + sdks/java/harness which is the portability container that is
meant to be used across all runners for Java jobs.

> Provide a way for user code to read dataflow runner stats

> Key: BEAM-7605
> URL: https://issues.apache.org/jira/browse/BEAM-7605

> Assignee: Steve Niemitz
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The dataflow runner collects (and publishes to the dataflow service) a large
> number of useful stats. While these can be polled from the dataflow service
> via its API, there are a few downsides to this:
> * it requires another process to poll and collect the stats
> * the stats are aggregated across all workers, so per-worker stats are lost
> It would be simple to provide a hook to allow users to receive stats updates
> as well, and then do whatever they want with them.
