Hi, Team, We are writing our own prometheus reporter to make sure that we are capturing data in histograms rather than summaries.
We were able to do it successfully in version 1.12.7. But while upgrading to version 1.14.3 , we find that MetricRegistryTestUtils is not available in the src code given by flink in github. PrometheusReporterTest.java throws error that this file is unavailable [image: Screen Shot 2022-02-01 at 11.50.09 AM.png] [image: Screen Shot 2022-02-01 at 11.53.17 AM.png] The below code is in 1.12.7 but method defaultMetricRegistryConfiguration is deprecated in the latest version.

It's not available in https://github.com/apache/flink/tree/master/flink-runtime/src/main/java/org/apache/flink/runtime/metrics master branch as well.
