Prometheus Reporter Enhancement

Hi all,

Would people appreciate enhancements to the prometheus reporter to include extra labels via a configuration, as a contribution to Flink? I can see it being useful for adding labels that are not job specific, but infra specific.

The change would be nicely integrated with the Flink’s ConfigOptions and unit tested.

Best,
Mason

Let's move this to the ticket then. :)

Hi Chesnay,

I would like to take on https://issues.apache.org/jira/browse/FLINK-17495 <https://issues.apache.org/jira/browse/FLINK-17495> as a contribution to OSS, if that’s alright with the team. We can discuss implementation details here or in the ticket, but I was thinking about modifying the ReporterScopedSettings to enable this generic tag support.

Best,
Mason

There is no plan to generally exclude label keys from the metric 
identifier/logical scope. They ensure that the label set for a given 
identifier/scope is unique, i.e., you can't have 2 metrics called 
"numRecordsIn" with different label sets. Changing this would also break 
all existing setups, so if anything if would have to be an opt-in feature.

What I envision more is for the user to have more control over the 
metric identifier/logical scope via the scope formats. They are 
currently quite limited by only controlling part of the final 
identifier, while the logical scope isn't controllable at all.

Generally though, there's a fair bit of internal re-structuring that 
we'd like to do before extending the metric system further, because 
we've been tacking on more and more things since it was released in 
1.3.0 (!!!) but barely refactored things to properly fit together.

Are there any plans to rework some of the metric name formulations (getMetricIdentifier or getLogicalScope)? Currently, the label keys and/or label values are concatenated in the metric name and the information is redundant and makes the metric names longer.

Would it make sense to remove the tag related information (getAllVariables())?

There is already a ticket for this. Note that this functionality should 
be implemented in a generic fashion to be usable for all reporters.
