[jira] [Commented] (AMQ-5497) Add a statistic to display the time the oldest message has been on the destination

["Timothy Bish (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMQ-5497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14256251#comment-14256251 ] 

Timothy Bish commented on AMQ-5497:
-----------------------------------

I just took a breif look, the first issue I see is that this would only tell you the oldest if the depth of the queue was not so great that the browse returned early due to memory constraints, otherwise you'd just get the time of the last message to fit into the browsers limits.

> Currently there is a method for tracking the longest a message was on a destination before it was processed, but this metric isn't updated until the message is consumed.  We have the need to display the length of time that the oldest message has been sitting on the destination.
