General options:
--threads=N number of threads to use [1]
--events=N limit for total number of events [0]
--time=N limit for total execution time in seconds [10]
--forced-shutdown=STRING number of seconds to wait after the --time limit before forcing shutdown, or 'off' to disable [off]
--thread-stack-size=SIZE size of stack per thread [64K]
--rate=N average transactions rate. 0 for unlimited rate [0]
--report-interval=N periodically report intermediate statistics with a specified interval in seconds. 0 disables intermediate reports [0]
--report-checkpoints=[LIST,...] dump full statistics and reset all counters at specified points in time. The argument is a list of comma-separated values representing the amount of time in seconds elapsed from start of test when report checkpoint(s) must be performed. Report checkpoints are off by default. []
--debug[=on|off] print more debugging info [off]
--validate[=on|off] perform validation checks where possible [off]
--help[=on|off] print help and exit [off]
--version[=on|off] print version and exit [off]
--config-file=FILENAME File containing command line options
--tx-rate=N deprecated alias for --rate [0]
--max-requests=N deprecated alias for --events [0]
--max-time=N deprecated alias for --time [0]
--num-threads=N deprecated alias for --threads [1]

Pseudo-Random Numbers Generator options:
--rand-type=STRING random numbers distribution {uniform,gaussian,special,pareto} [special]
--rand-spec-iter=N number of iterations used for numbers generation [12]
--rand-spec-pct=N percentage of values to be treated as 'special' (for special distribution) [1]
--rand-spec-res=N percentage of 'special' values to use (for special distribution) [75]
--rand-seed=N seed for random number generator. When 0, the current time is used as a RNG seed. [0]
--rand-pareto-h=N parameter h for pareto distribution [0.2]

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]

General database options:

--db-driver=STRING specifies database driver to use ('help' to get list of available drivers) [mysql]
--db-ps-mode=STRING prepared statements usage mode {auto, disable} [auto]
--db-debug[=on|off] print database-specific debug information [off]
