Still need to switch compaction info to throughput instead of load / size.

Are we talking about (user defined throttle / compacting file sizes)? if yes
then we will be penalizing instances which can do more on disk...
IMHO: the bigger the compaction bigger the file cache misses and more memory
pressure, hence we added the size/load in the first place.

> This ticket is to continue the discussion in CASSANDRA-5255.
> Currently Dsnitch reports the Severity by calculating the amount of data
> compacting relative to load of the node.
> It will be nice to report Severity as a factor of load average, N/W
> Throughput and IO Wait instead.
> http://www.hyperic.com/products/sigar seem to have it (But personally i have
