We currently do not compute sums for Histograms, and hence this isn't
exported to Prometheus.
You'd need to use custom histogram (that actually computes sums) and a
custom prometheus reporter (that extracts said sum if present) to
implement this yourself.

Hi,
I am currently registering a Flink Histogram and using the Prometheus
Metrics Reporter to send this metric to our Time Series Data Storage.
When Prometheus grabs this metric and converts it to the "summary"
type, there is no sum found (only the streaming quantiles and count).
This is causing an issue when our metrics agent is attempting to
capture the Flink Histogram/Prometheus Summary.
I was wondering if in a newer version (than 1.13.6) the histogram sum
is computed by Flink and what that version would be? If not, is there
any work around so that a Flink histogram can emit all 3 elements
(quantiles, sum, and count) in Prometheus format?
