Jonathan Ellis commented on CASSANDRA-5306:
-------------------------------------------
iowait code looks good. Still need to switch compaction info to throughput
instead of load / size.
Other nits:
- Catch should log at info (warn?) that it couldn't open the stats file.
(Better: be smart and only log warn if Linux.)
- Methods that are only used internally by BAM should be private
- empty catch should log ioexception at debug, just in case
> Improve Dsnitch Severity

> 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
> not used it).
