Zhu Zhu commented on FLINK-14164: --------------------------------- Agreed. 1,2 for release-1.9 and master(1.10). 4 for master(1.10). 3 should be in 1.11. I think we can add a underlying counter which can help both the {{fullRestarts}} and {{numberOfRestarts}}. It need not to be registered into to the metric registry. Each global failover or task failover should increment it. > Add a metric to show failover count regarding fine grained recovery > ------------------------------------------------------------------- > > Key: FLINK-14164 > URL: https://issues.apache.org/jira/browse/FLINK-14164 > Project: Flink > Issue Type: Improvement > Components: Runtime / Coordination, Runtime / Metrics > Affects Versions: 1.9.0, 1.10.0 > Reporter: Zhu Zhu > Priority: Major > Fix For: 1.10.0 > > > Previously Flink uses restart all strategy to recover jobs from failures. And > the metric "fullRestart" is used to show the count of failovers. > However, with fine grained recovery introduced in 1.9.0, the "fullRestart" > metric only reveals how many times the entire graph has been restarted, not > including the number of fine grained failure recoveries. > As many users want to build their job alerting based on failovers, I'd > propose to add such a new metric {{numberOfFailures}}/{{numberOfRestarts}} > which also respects fine grained recoveries. -- This message was sent by Atlassian Jira (v8.3.4#803005)
