Nikita Amelchev updated IGNITE-29277:
-------------------------------------
Fix Version/s: 2.20
> Add a histogram of currently held explicit locks
> ------------------------------------------------
>
> Key: IGNITE-29277
> URL: https://issues.apache.org/jira/browse/IGNITE-29277
> Project: Ignite
> Issue Type: Task
> Reporter: Nikita Amelchev
> Assignee: Nikita Amelchev
> Priority: Major
> Fix For: 2.20
>
>
> {{MaxExplicitLockHoldTime}} reports only the longest hold time among the
> explicit locks currently held, and {{ExplicitLockHoldTimeHistogram}} accounts
> for a lock only after it is released. So there is no way to see how many
> locks are being held for too long right now: a single forgotten lock cannot
> be told apart from a mass leak, and an alert cannot be set on the number of
> such locks. A histogram of hold times of the currently held locks would show
> it, with the threshold of a long-held lock configured as the histogram bound.
