incorporated com.codahale.metrics instead of hand-rolled reporting
reduces complexity and provides nice things like latency histograms and windowed average throughput
Just ran some tests with this version/PR. These stats are perfect. Yes, please merge.
sysbench.updates
count = 84020
mean rate = 841.61 calls/second
1-minute rate = 792.20 calls/second
5-minute rate = 350.10 calls/second
15-minute rate = 230.03 calls/second
min = 0.68 milliseconds
max = 58.55 milliseconds
mean = 6.69 milliseconds
stddev = 3.97 milliseconds
median = 5.63 milliseconds
75% <= 7.00 milliseconds
95% <= 12.76 milliseconds
98% <= 20.43 milliseconds
99% <= 25.25 milliseconds
99.9% <= 40.46 milliseconds
After testing a bit more with this fork, a couple issues:
- Somehow the ability to observe RUN_TIME_MINUTES is broken, it just runs forever.
- The reporting as listed above should show up at the end only (or an option).
- The sysbench-deletes file systems to always be all zeros(?).
These are just a couple things I see at first glance.
I'm all caught up on the other PRs, so I'll be looking at how to incorporate this soon.
It should be possible to tighten up the output format by manually getting and printing metrics, I know that was one of your concerns, Tim.
Cheers, Leif
