STORM-1118: Added test to compare latency vs. throughput in storm.
Also added a metrics gathering server for testing, an HdrHistogram based
metric, and CPU utilization metric using sigar.
This should provide a simple test for comparing different versions of storm
to one another or different hardware options. The goal is to produce a load at
a given throughput and measure the latency it takes the system to process that
throughput. Generally if you have a given SLA you want the same hardware to
handle the most throughput possible to meet your SLA.
The current test uses word count, but should easily be extended to handle
more complex processing.
