Till Rohrmann commented on FLINK-14164: --------------------------------------- Can't we deprecate the {{fullRestarts}} metric in {{1.10}}? Otherwise we will only be able to remove it in {{1.12}} if it's deprecated in {{1.11}}. > 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: 1.10.0 > 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)
