# sysbench

sysbench is a scriptable multi-threaded benchmark tool based on
LuaJIT. It is most frequently used for database benchmarks, but can also
be used to create arbitrarily complex workloads that do not involve a
database server.

sysbench comes with the following bundled benchmarks:

- `oltp_*.lua`: a collection of OLTP-like database benchmarks
- `fileio`: a filesystem-level benchmark
- `cpu`: a simple CPU benchmark
- `memory`: a memory access benchmark
- `threads`: a thread-based scheduler benchmark
- `mutex`: a POSIX mutex benchmark

## Features

- extensive statistics about rate and latency is available, including
  latency percentiles and histograms;
- low overhead even with thousands of concurrent threads. sysbench is
  capable of generating and tracking hundreds of millions of events per
  second;
- new benchmarks can be easily created by implementing pre-defined hooks
  in user-provided Lua scripts;
- can be used as a general-purpose Lua interpreter as well, simply
  replace `#!/usr/bin/lua` with `#!/usr/bin/sysbench` in your script.

# Installing from Binary Packages

## Linux

The easiest way to download and install sysbench on Linux is using
binary package repositories hosted by
[packagecloud](https://packagecloud.io). The repositories are
automatically updated on each sysbench release. Currently x86_64, i386
and aarch64 binaries are available.

Multiple methods to download and install sysbench packages are available and
described at <https://packagecloud.io/akopytov/sysbench/install>.

Quick install instructions:

- Debian/Ubuntu
  ``` shell
  curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.deb.sh | sudo bash
  sudo apt -y install sysbench
  ```

- RHEL/CentOS:
  ``` shell
  curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
  sudo yum -y install sysbench
  ```

- Fedora:
  ``` shell
  curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash	
  sudo dnf -y install sysbench
  ```

## macOS

On macOS, up-to-date sysbench packages are available from Homebrew:
```shell
# Add --with-postgresql if you need PostgreSQL support
brew install sysbench
```

## Windows
As of sysbench 1.0 support for native Windows builds was dropped. It may
be re-introduced in later releases. Currently, the recommended way to
obtain sysbench on Windows is
using
[Windows Subsystem for Linux available in Windows 10](https://msdn.microsoft.com/en-us/commandline/wsl/about).

After installing WSL and getting into he bash prompt on Windows
following Debian/Ubuntu installation instructions is
sufficient. Alternatively, one can use WSL to build and install sysbench
from source, or use an older sysbench release to build a native binary.

# Building and Installing From Source

It is recommended to install sysbench from the official binary
packages as described in
[Installing from Binary Packages](#installing-from-binary-packages). Below
are instruction for cases when you want to use sysbench on an
architecture for which no binary packages are available.

## Build Requirements

### Windows
As of sysbench 1.0 support for native Windows builds was
dropped. It may be re-introduced in later versions. Currently, the
recommended way to build sysbench on Windows is using
[Windows Subsystem for Linux available in Windows 10](https://msdn.microsoft.com/en-us/commandline/wsl/about).

After installing WSL and getting into bash prompt on Windows, following
Debian/Ubuntu build instructions is sufficient. Alternatively, one can
build and use an older 0.5 release on Windows.

### Debian/Ubuntu
``` shell
    apt -y install make automake libtool pkg-config libaio-dev vim-common
    # For MySQL support
    apt -y install libmysqlclient-dev
    # For PostgreSQL support
    apt -y install libpq-dev
```

### RHEL/CentOS
``` shell
    yum -y install make automake libtool pkgconfig libaio-devel vim-common
    # For MySQL support, replace with mysql-devel on RHEL/CentOS 5
    yum -y install mariadb-devel
    # For PostgreSQL support
    yum -y install postgresql-devel
```

### Fedora
``` shell
    dnf -y install make automake libtool pkgconfig libaio-devel vim-common
    # For MySQL support
    dnf -y install mariadb-devel
    # For PostgreSQL support
    dnf -y install postgresql-devel
```

### macOS

Assuming you have Xcode (or Xcode Commane Line Tools) and Homebrew installed:
``` shell
    brew install automake libtool openssl pkg-config
    # For MySQL support
    brew install mysql
    # For PostgreSQL support
    brew install postgresql
```

## Build and Install
``` shell
    ./autogen.sh
    # Add --with-pgsql to build with PostgreSQL support
    LDFLAGS=-L/usr/local/opt/openssl/lib ./configure
    make -j
    make install
```

The above will build sysbench with MySQL support by default. If you have
MySQL headers and libraries in non-standard locations (and no
`mysql_config` can be found in the `PATH`), you can specify them
explicitly with `--with-mysql-includes` and `--with-mysql-libs` options
to `./configure`.

To compile sysbench without MySQL support, use `--without-mysql`. If no
database drivers are available database-related scripts will not work,
but other benchmarks will be functional.

See [README-Oracle.md](README-Oracle.md) for instructions on building
with Oracle client libraries.

# Usage

## General syntax

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 the `fileio`
	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](README.md#general-command-line-options)
	for a description of general options provided by sysbench itself.


You can use `sysbench --help` to display the general command line syntax
and options.

## General command line options

The table below lists the supported common options, their descriptions and default values:

*Option*              | *Description* | *Default value*

| `--verbosity`         | Verbosity level (0 - only critical messages, 5 - debug)                                                                                                                                                                                                                                                                                                                                                                                                                 | 4               |
| `--percentile`        | sysbench measures execution times for all processed requests to display statistical information like minimal, average and maximum execution time. For most benchmarks it is also useful to know a request execution time value matching some percentile (e.g. 95% percentile means we should drop 5% of the most long requests and choose the maximal value from the remaining ones). This option allows to specify a percentile rank of query execution times to count | 95              |

Note that numerical values for all *size* options (like `--thread-stack-size` in this table) may be specified by appending the corresponding multiplicative suffix (K for kilobytes, M for megabytes, G for gigabytes and T for terabytes).
