[jira] [Commented] (DISPATCH-1463) Detect deliveries that are stuck
in the router for a long time
[ https://issues.apache.org/jira/browse/DISPATCH-1463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16960035#comment-16960035 ]

ted-ross commented on pull request #600: DISPATCH-1463 - Add detection for stuck deliveries
URL: https://github.com/apache/qpid-dispatch/pull/600
The current delayed-delivery counts are limited in that they only count deliveries that have been settled. These counters do not count deliveries that are currently "stuck" and have not been settled.
This feature provides visibility into the number of stuck deliveries per link and per router.
A new counter "deliveriesStuck" shall be added to the link and router entities for per-link and aggregated-per-router respectively.
A delivery is considered "stuck" when it has been in the undelivered or unsettled lists for more than ten seconds and is still not settled. Once a stuck delivery is settled or otherwise removed, it is no longer considered stuck.
When a link transitions from zero to one stuck delivery, an INFO log message shall be emitted indicating that at least one delivery is stuck on that link.
