No Prometheus histogram Metrics found

[icarus]

I deployed the dynatrace-operator in my k8s cluster and use the annotations to monitor my workloads.

However, I can't found the prometheus histogram type metrics in the Data Explorer.
Here's my instance: 

"envoy_http_downstream_rq_time" histogram type metrics in my workloads.

The Data explorer only shows "envoy_http_downstream_rq_time_count" and "envoy_http_downstream_rq_time_sum.count" but no "envoy_http_downstream_rq_time_bucket" found.

I also checked all of the dynatrace pods and no error logs found.

Hey Icarus, I would recommend looking at the metric dsfm:server.metrics.rejections to see if there are any rejection reasons in there, but then there are also a bunch of other self monitoring metrics that could help, they start with dsfm:server and dsfm:activegate. Another that could be useful is dsfm:active_gate.kubernetes.api.query_count to ensure it's querying successfully. Hope these help!
