Akshay Iyangar commented on BEAM-7438:
--------------------------------------
[~mxm] - so gauges with the current code still didn't work for me, I had to
change the return type from `GaugeResult` to `Long` to see the values on the
flink UI.

Also for the Distribution, I think we will probably have to implement Flink's
histogram
but I saw this effort which will probably make it easier to implement the
distribution because while implementing I too observed the same problems
mentioned below is that we need quantiles for calculating histogram in Flink
and DistributionResult just doesn't give that and is pretty basic.

Let me know, what you think.

> Distributions and gauge metrics are not visible at Flink dashboard neither
> Prometheus IO.
> I was able to debug the runner code and see that these metrics are being
> update over *FlinkMetricContainer#updateDistributions()* and
> *FlinkMetricContainer#updateGauges()* (meaning they are treated as "attempted
> metrics") but these are not visible when looking them over the Flink
> Dashboard or Prometheus. In the other hand, *Counter* metrics work as
> expected.
