1、通用语法
The general command line syntax for sysbench is:
sysbench [options]... [testname] [command]
-
testname is an optional name of a built-in test (e.g.
fileio,
memory,cpu, etc.), or a name of one of the bundled Lua scripts
(e.g.oltp_read_only), or a path to a custom Lua script. If no
test name is specified on the command line (and thus, there is no
command too, as in that case it would be parsed as a testname), or
the test name is a dash (“-”), then sysbench expects a Lua script to
execute on its standard input. -
command is an optional argument that will be passed by sysbench to
the built-in test or script specified with testname. command
defines the action that must be performed by the test. The list of
available commands depends on a particular test. Some tests also
implement their own custom commands.Below is a description of typical test commands and their purpose:
prepare: performs preparative actions for those tests which need
them, e.g. creating the necessary files on disk for thefileio
test, or filling the test database for database benchmarks.run: runs the actual test specified with the testname
argument. This command is provided by all tests.cleanup: removes temporary data after the test run in those
tests which create one.help: displays usage information for the test specified with the
testname argument. This includes the full list of commands
provided by the test, so it should be used to get the available
commands.
-
options is a list of zero or more command line options starting with
'--'. As with commands, thesysbench testname helpcommand
should be used to describe available options provided by a
particular test.
You can use sysbench --help to display the general command line syntax
and options.
