But striped pool monitoring is right approach, but need to do it more human understandable. In general we are already getting all queue's items in log when starvation detected, but it does not suitable. I think so only list of message in queue will not be useful for high level user. I will want to see statistic information: # What is duration of handle of particular message? # How long the message hold in the queue? # What is the message mean? (in human readable format) # How to determine not typical duration of message? was (Author: v.pyatkov): Hi, I am think view of queue through system view will be not enough to understanding what issue that is.

In the case queue size > becomes large it's useful to have the ability to know what tasks are waiting > for execution in the thread pool. > Especially, for dealing with failover scenarios. > We should create a system views to expose information about striped executor > services queue. -- This message was sent by Atlassian Jira (v8.3.4#803005)
