SysBench是一个模块化的、跨平台、多线程基准测试工具，主要用于评估测试各种不同系统参数下的数据库负载情况。它主要包括以下几种方式的测试： 

• 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, the sysbench testname help command should be used to describe available options provided by a particular test.
  See General command line options for a description of general options provided by sysbench itself.
