Rakesh R commented on BOOKKEEPER-736:
-------------------------------------
bq. I don't know if NumUrLedgers, NumRereplicatedLedgers is useful, since it
doesn't indicated the number of under replicated ledgers in the cluster at a
given point
At a given point of time the following autorecovery stats gives :
# _NumUrLedgers_ -> the total number of under replicated ledgers in the BK
cluster
# _NumRereplicatedLedgers_ -> the total number of ledgers which a bookie(say
BK1) has successfully re-replicated to itself.
IMHO these statistics would be helpful to the administrators to watch the
stability of the BK cluster.
bq. I would suggest leave them out and re-consider adding them back if there is
a use case that need them.
It would be good to expose these info. Also, welcome others opinion.
Thanks,
Rakesh
