Log options:
--verbosity=N verbosity level {5 - debug, 0 - only critical messages} [3]
--percentile=N percentile to calculate in latency statistics (1-100). Use the special value of 0 to disable percentile calculations [95]
--histogram[=on|off] print latency histogram in report [off]

sysbench对数据库进行压力测试的过程
- prepare 这个阶段是用来做准备的、建立好测试用的表、并向表中填充数据。
- run 这个阶段是才是去跑压力测试的SQL
- cleanup 这个阶段是去清除数据的、也就是prepare阶段初始化好的表要都drop掉。
