> Add explicit lock hold time metrics
> -----------------------------------

> Key: IGNITE-29108
> URL: https://issues.apache.org/jira/browse/IGNITE-29108
> Project: Ignite
> Issue Type: Improvement
> Reporter: Nikita Amelchev
> Assignee: Nikita Amelchev
> Priority: Major
> Fix For: 2.19
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> There is no way to see how long explicit locks acquired with
> IgniteCache.lock() are held. A lock leaked by an application blocks other
> threads and the partition map exchange, but it is neither a transaction nor a
> future, so neither the metrics nor the long running operations dump show it.
> Add the maximum hold time of the explicit locks currently held on the node
> and a histogram of hold times of released explicit locks to the tx metric
> registry.
