Michael Dürig commented on OAK-7854:
------------------------------------

I suggest to expose the flush rate via a meter: 
[https://github.com/mduerig/jackrabbit-oak/commit/1e8330c9694b82a80448535197bb16062b742f2f]

This commit is based on the 
[https://github.com/mduerig/jackrabbit-oak/commits/OAK-7852-2] branch from 
OAK-7852. However it would be simple enough to decouple it should we decide on 
a different approach there.

[~frm], could you have a look?

> The FileStore background operations are ultimately executed through a 
> {{ScheduledExecutorService}}. In the case this scheduling gets blocked (e.g. 
> because of a deadlock or lock contention in one of its tasks) there is chance 
> of repository corruption. 
> To minimise potential data loss we should implement monitoring endpoints for 
> the vital background operations. This would allow deployments to take action 
> early in case of failures and thus minimise potential data loss and simplify 
> recovery.
