             Summary: Flink Histogram not emitting min and max when using Prometheus Reporter
                 Key: FLINK-29984
                 URL: https://issues.apache.org/jira/browse/FLINK-29984
             Project: Flink
          Issue Type: New Feature
          Components: Runtime / Metrics
    Affects Versions: 1.13.6
            Reporter: Lim Qing Wei


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?
