Piotr Nowojski created FLINK-35065: -------------------------------------- Summary: Add numFiredTimers and numFiredTimersPerSecond metrics Key: FLINK-35065 URL: https://issues.apache.org/jira/browse/FLINK-35065 Project: Flink Issue Type: Improvement Components: Runtime / Metrics, Runtime / Task Affects Versions: 1.19.0 Reporter: Piotr Nowojski Assignee: Piotr Nowojski Fix For: 1.20.0
Currently there is now way of knowing how many timers are being fired by Flink, so it's impossible to distinguish, even using code profiling, if operator is firing only a couple of heavy timers per second using ~100% of the CPU time, vs firing thousands of timer per seconds. We could add the following metrics to address this issue: * numFiredTimers - total number of fired timers per operator * numFiredTimersPerSecond - per second rate of firing timers per operator -- This message was sent by Atlassian Jira (v8.20.10#820010)
