> From IRC this morning:
> {code}
> 07:26 < ntelford> is there a way to monitor the number and size of
> store files *per region*?
> 07:26 < ntelford> I know region servers expose a metric on the total
> across all regions, but that's fairly unhelpful to us
> ...
> 08:11 < St^Ack> ntelford: no. number is easy but when you say size,
> you mean size of all the storefiles in the region, not the size per
> storefile (asking because one of the lads is exposing per region
> metrics at mo and those would be easy to add)
> 08:12 < ntelford> St^Ack, for size we're actually interested in the
> individual store file size
> 08:13 < St^Ack> ntelford: how would we do that in metric?  metric
> would be dynamic
> 08:13 < ntelford> specifically, we want to monitor: the maximum,
> minimum, mean (and some percentiles) number of store files within a
> region
> ...
> 08:13 < ntelford> and the maximum, minimum, mean (+ percentiles) size
> of individual store files
> 08:13 < ntelford> :)
> 08:13 < St^Ack> now you are verging on abuse!
