Jeff Jirsa reopened CASSANDRA-13234: ------------------------------------ Reopening - [~aweisberg] correctly notes that there's a (likely rare) edge case where FD thinks the host is up, we try to replay hints, hint replay fails, but we update metrics incorrectly anyway. Submitting a modification where we update the hint delay histograms in the response callback, rather than before sending, just in case the hint dispatch fails. [~spo...@gmail.com] or [~aweisberg] - either of you care to review the modification (pushed to the same trunk cassandra-13234 branch above). > Add histogram for delay to deliver hints > ---------------------------------------- > > Key: CASSANDRA-13234 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13234 > Project: Cassandra > Issue Type: Improvement > Components: Observability > Reporter: Jeff Jirsa > Assignee: Jeff Jirsa > Priority: Minor > Fix For: 4.0 > > > There is very little visibility into hint delivery in general - having > histograms available to understand how long it takes to deliver hints is > useful for operators to better identify problems. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
