Windows

    The latest stable version is 1.7.9:

    To check the integrity, use cmdlet on PowerShell.

    Download a ZIP archive from the download page. There are installers for 32-bit and 64-bit environments, so choose one suitable for your environment.

    Then you need to expand the ZIP archive. You can do this by clicking “Extract All” on Explorer, or if you’re using PowerShell, you can use Expand-Archive cmdlet.

    1. PS> Expand-Archive td-agent-bit-1.7.9-win64.zip

    The ZIP package contains the following set of files.

    1. td-agent-bit
    2. ├── bin
    3. │   ├── fluent-bit.dll
    4. │   └── fluent-bit.exe
    5. ├── conf
    6. │   ├── fluent-bit.conf
    7. │   ├── parsers.conf
    8. │   └── plugins.conf
    9. └── include
    10.     │   ├── flb_api.h
    11.     │   ├── ...
    12.     │   └── flb_worker.h

    Now, launch cmd.exe or PowerShell on your machine, and execute fluent-bit.exe as follows.

    1. PS> .\bin\fluent-bit.exe -i dummy -o stdout

    If you see the following output, it’s working fine!

    1. PS> .\bin\fluent-bit.exe  -i dummy -o stdout

    To halt the process, press CTRL-C in the terminal.

    Then, double-click the EXE installer you’ve downloaded. Installation wizard will automatically start.

    Click Next and proceed. By default, Fluent Bit is installed into C:\Program Files\td-agent-bit\, so you should be able to launch fluent-bit as follow after installation.

    Windows services are equivalent to “daemons” in UNIX (i.e. long-running background processes). Since v1.5.0, Fluent Bit has the native support for Windows Service.

    Suppose you have the following installation layout:

    1. C:\fluent-bit\
    2. ├── conf
    3. │   ├── fluent-bit.conf
    4. │   └── parsers.conf
    5.     ├── fluent-bit.dll
    6.     └── fluent-bit.exe

    To register Fluent Bit as a Windows service, you need to execute the following command on Command Prompt. Please be careful that a single space is required after .

    1. % sc.exe create fluent-bit binpath= "\fluent-bit\bin\fluent-bit.exe -c \fluent-bit\conf\fluent-bit.conf"

    Now Fluent Bit can be started and managed as a normal Windows service.

    1. % sc.exe start fluent-bit
    2. % sc.exe query fluent-bit
    3. SERVICE_NAME: fluent-bit
    4.     TYPE               : 10  WIN32_OWN_PROCESS
    5.     STATE              : 4 Running
    6.     ...

    To halt the Fluent Bit service, just execute the “stop” command.

    1. % sc.exe stop fluent-bit

    First, you need Microsoft Visual C++ to compile Fluent Bit. You can install the minimum toolkit by the following command:

    When asked which packages to install, choose “C++ Build Tools” (make sure that “C++ CMake tools for Windows” is selected too) and wait until the process finishes.

    Also you need to install flex and bison. One way to install them on Windows is to use .

    1. PS> wget -o winflexbison.zip https://github.com/lexxmark/winflexbison/releases/download/v2.5.22/win_flex_bison-2.5.22.zip
    2. PS> Expand-Archive winflexbison.zip -Destination C:\WinFlexBison
    3. PS> cp -Path C:\WinFlexBison\win_bison.exe C:\WinFlexBison\bison.exe
    4. PS> cp -Path C:\WinFlexBison\win_flex.exe C:\WinFlexBison\flex.exe
    5. PS> setx /M PATH "%PATH%;C:\WinFlexBison"

    Also you need to install git to pull the source code from the repository.

    1. PS> wget -o git.exe https://github.com/git-for-windows/git/releases/download/v2.28.0.windows.1/Git-2.28.0-64-bit.exe
    2. PS> start git.exe

    Open the start menu on Windows and type “Developer Command Prompt”.

    Clone the source code of Fluent Bit.

    1. % git clone https://github.com/fluent/fluent-bit
    2. % cd fluent-bit/build

    Compile the source code.

    1. % cmake .. -G "NMake Makefiles"
    2. % cmake --build .

    Now you should be able to run Fluent Bit:
