  sysbench [options]... [testname] [command]

Commands implemented by most tests: prepare run cleanup help

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)
  --db-ps-mode=STRING prepared statements usage mode {auto, disable} [auto]
  --db-debug[=on|off] print database-specific debug information [off]
