Matteo Bertozzi commented on HBASE-7615:
----------------------------------------
[~eclark] what do you suggest instead? I just want to keep track of min/max/avg
time of snapshots...
As far as I know, we don't have a way to store metrics like [snapshot: time]
so at the moment just having an idea of how long on avg it takes taking a
snapshot or restoring is a step forward.
I've used the histogram because is the same used by the log splitting, that is
quite similar to the snapshot workload... do you think that also the log split
metrics doesn't make sense?

> Metrics should be added for snapshot.
> From Matteo: Output that we have in SnapshotInfo should be covered:
> "%d HFiles (%d in archive), total size %s (%.2f%% %s shared with the source
> table)"
> Jesse mentioned snaphot counts, average time to completion.
> I think we should have counts for successful / failed snapshots.
