Andrei Dulceanu commented on OAK-4742:
--------------------------------------

[~mduerig], does it make sense to expose the methods suggested in the 
description in a new MBean, like {{SegmentStoreStatsMBean}}? Trying to come up 
with a first patch I realised that all the instrumentation is centred around 
{{SegmentNodeStore}}...

> Improve FileStoreStatsMBean

> We should add further data to that MBean (if feasible):
> * Number of commits
> * Number of commits queuing (blocked on the commit semaphore)
> * Percentiles of commit times (exclude queueing time)
> * Percentiles of commit queueing times 
> * Last gc run / size before gc and after gc / time gc took broken down into 
> the various phases
