What exactly do you mean with "count metrics" and "sum"?

Given a Histogram H, you should see:
- one time series named <scope>H_count
- one time series named <scope>H, with various labels for the different quantiles.

What do you see in Prometheus, and what do you consider to be missing?

Hi All,

I have added histogram to code following here <https://ci.apache.org/projects/flink/flink-docs-stable/ops/metrics.html#histogram>. But I observe that on prometheus board I get only count metrics, not sum. Metrics itself is missing.
I have used classes:
com.codahale.metrics.Histogram
org.apache.flink.dropwizard.metrics.DropwizardHistogramWrapper
What do I miss here?
