Sysbench multi-thread Performance Testing Tool

Recently, sysbench has been used for many performance tests. It also summarizes its features and usage and precautions. Sysbench is a multi-thread performance testing tool that can perform performance tests such as CPU, memory, IO, and database. However, most of the time I use it to perform oltp tests on databases (MySQL. What can it test and how can it help me to answer the question.
~ /Zbs $ sysbench -- help
Missing required command argument.
Usage:
Sysbench [general-options]... -- test = <test-name> [test-options]... command
In the above general usage, -- test = specifies the type to be tested. What types of -- test are available? Fileio/cpu/memory/threads/mutex. Sorry, I have never tested the above. I mainly use it to test the database performance, but why is there no database option, I used the latest version 0.5. The biggest difference between it and 0.4 is that it supports multi-table testing, real-time printing of statistics, and custom lua scripts to set test behaviors.
Compiled-in tests:
Fileio-File I/O test
Cpu-CPU performance test
Memory-Memory functions speed test
Threads-Threads subsystem performance test
Mutex-Mutex performance test
If you use sysbench0.4, you will probably see the following. Note that the oltp option is used for database testing.
Compiled-in tests:
Fileio-File I/O test
Cpu-CPU performance test
Memory-Memory functions speed test
Threads-Threads subsystem performance test
Mutex-Mutex performance test
Oltp-OLTP test
After reading the test mode, what other control parameters does it have? First, let's take a look at the sysbench -- test = <test-mode> help parameter specific to each test mode. For example, here I am (please note that, because the -- test option of sysbench0.5 does not use the oltp option for database testing, but by specifying the lua script, the following results cannot be viewed using the preceding command, so if you want to check whether it is still through 0.4, if anyone finds a way to view the oltp parameters in version 0.5, please let us know. In addition, although versions 0.5 and 0.4 are different, the parameters are basically compatible ):
~ $ Sysbench -- test = oltp help

There are so many parameters, I believe they can be basically understood. I will discuss the meaning of the parameters in the examples below. After knowing how to view the usage of a specific test mode, let's take a look at general-options and common parameters. Let's take a look at the 0.5 parameter (a lot more than 0.4 is added, and some parameter names have also changed, how to identify --- explain a parameter exactly ):
General options:
-- Num-threads = N number of threads to use [1]
-- Max-requests = N limit for total number of requests [1, 10000]

-- 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 completed MED. report checkpoints are off by default. []
