Subject [jira] [Commented] (FLINK-8043) change fullRestarts (for fine grained recovery) from guage to counter
Date Mon, 08 Jan 2018 16:47:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-8043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16316573#comment-16316573

Till Rohrmann commented on FLINK-8043:
--------------------------------------

Hi [~stevenz3wu], I think {{fullRestarts}} should be a {{Gauge}}, because the actual value
is stored within the {{ExecutionGraph}}. Therefore, there is no need to introduce a new state
variable to count the number of full restarts. But maybe I don't fully understand the underlying
problem.

> Fine grained recovery publish fullRestarts as guage, which is not suitable for threshold
based alerting. Usually we would alert like "fullRestarts > 0 happens 10 times in last
15 minutes".
> In comparison, "task_failures" is published as counter.
