Jörn Kottmann created FLINK-15438: ------------------------------------- Summary: Counter metrics are incorrectly reported as total counts to DataDog Key: FLINK-15438 URL: https://issues.apache.org/jira/browse/FLINK-15438 Project: Flink Issue Type: Bug Components: Runtime / Metrics Affects Versions: 1.9.1 Reporter: Jörn Kottmann
The Flink semantics of a counter are not matching with the counters in DataDog. In Flink a counter counts the total of increment and decrement calls. In DataDog a counter is a rate over the reporting interval. The Flink implementation of the DataDog reporter seems to send the Flink counter value each time the metrics are reported. Correct would be to send the delta of the counter since the last report. There are some features in DataDog which are easier to use if this could be fixed, e.g. alerts based on counters. -- This message was sent by Atlassian Jira (v8.3.4#803005)
