Windows

Fluent Bit is distributed as fluent-bit package for Windows. Fluent Bit has two flavours of Windows installers: a ZIP archive (for quick testing) and an EXE installer (for system installation).

Configuration

Make sure to provide a valid Windows configuration with the installation, a sample one is shown below:

[SERVICE]
    # Flush
    # =====
    # set an interval of seconds before to flush records to a destination
    flush        5

    # Daemon
    # ======
    # instruct Fluent Bit to run in foreground or background mode.
    daemon       Off

    # Log_Level
    # =========
    # Set the verbosity level of the service, values can be:
    #
    # - error
    # - warning
    # - info
    # - debug
    # - trace
    #
    # by default 'info' is set, that means it includes 'error' and 'warning'.
    log_level    info

    # Parsers File
    # ============
    # specify an optional 'Parsers' configuration file
    parsers_file parsers.conf

    # Plugins File
    # ============
    # specify an optional 'Plugins' configuration file to load external plugins.
    plugins_file plugins.conf

    # HTTP Server
    # ===========
    # Enable/Disable the built-in HTTP Server for metrics
    http_server  Off
    http_listen  0.0.0.0
    http_port    2020

    # Storage
    # =======
    # Fluent Bit can use memory and filesystem buffering based mechanisms
    #

Migration to Fluent Bit

From version 1.9.0, td-agent-bit is a deprecated package and was removed after 1.9.9. The correct package name to use now is fluent-bit.

Installation Packages

The latest stable version is 1.9.10, each version is available on the Github release as well as at https://releases.fluentbit.io/<Major Version>/Major>fluent-bit-<Full Version>-win[32|64].[exe|zip]:

INSTALLERS

SHA256 CHECKSUMS

To check the integrity, use Get-FileHash cmdlet on PowerShell.

PS> Get-FileHash fluent-bit-1.9.10-win32.exe

Installing from ZIP archive

Download a ZIP archive from above. 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.

PS> Expand-Archive fluent-bit-1.9.10-win64.zip

The ZIP package contains the following set of files.

fluent-bit
├── bin
│   ├── fluent-bit.dll
│   └── fluent-bit.exe
│   └── fluent-bit.pdb
├── conf
│   ├── fluent-bit.conf
│   ├── parsers.conf
│   └── plugins.conf
└── include
    │   ├── flb_api.h
    │   ├── ...
    │   └── flb_worker.h
    └── fluent-bit.h

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

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

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

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

[3] dummy.0: [1561684388.441405800, {"message"=>"dummy"}]

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

Installing from EXE installer

Double-click the EXE installer you've downloaded. The installation wizard will automatically start.

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

PS> C:\Program Files\fluent-bit\bin\fluent-bit.exe -i dummy -o stdout

Installer options

To silently install to C:\fluent-bit directory here is an example:

PS> <installer exe> /S /D=C:\fluent-bit

The uninstaller automatically provided also supports a silent un-install using the same /S flag. This may be useful for provisioning with automation like Ansible, Puppet, etc.

Windows Service Support

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:

C:\fluent-bit\
├── conf
│   ├── fluent-bit.conf
│   └── parsers.conf
│   └── plugins.conf
└── bin
    ├── fluent-bit.dll
    └── fluent-bit.exe
    └── fluent-bit.pdb

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 binpath=.

% 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.

% sc.exe start fluent-bit
% sc.exe query fluent-bit
SERVICE_NAME: fluent-bit
    TYPE               : 10  WIN32_OWN_PROCESS
    STATE              : 4 Running
    ...

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

% sc.exe stop fluent-bit

To start Fluent Bit automatically on boot, execute the following:

% sc.exe config fluent-bit start= auto

[FAQ] Fluent Bit fails to start up when installed under `C:\Program Files`

Quotations are required if file paths contain spaces. Here is an example:

% sc.exe create fluent-bit binpath= "\"C:\Program Files\fluent-bit\bin\fluent-bit.exe\" -c \"C:\Program Files\fluent-bit\conf\fluent-bit.conf\""

[FAQ] How can I manage Fluent Bit service via PowerShell?

Instead of sc.exe, PowerShell can be used to manage Windows services.

Create a Fluent Bit service:

PS> New-Service fluent-bit -BinaryPathName "C:\fluent-bit\bin\fluent-bit.exe -c C:\fluent-bit\conf\fluent-bit.conf" -StartupType Automatic

Start the service:

PS> Start-Service fluent-bit

Query the service status:

PS> get-Service fluent-bit | format-list
Name                : fluent-bit
DisplayName         : fluent-bit
Status              : Running
DependentServices   : {}
ServicesDependedOn  : {}
CanPauseAndContinue : False
CanShutdown         : False
CanStop             : True
ServiceType         : Win32OwnProcess

Stop the service:

PS> Stop-Service fluent-bit

Remove the service (requires PowerShell 6.0 or later)

PS> Remove-Service fluent-bit

Compile from Source

If you need to create a custom executable, you can use the following procedure to compile Fluent Bit by yourself.

Preparation

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

PS> wget -o vs.exe https://aka.ms/vs/16/release/vs_buildtools.exe
PS> start vs.exe

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.

PS> wget -o winflexbison.zip https://github.com/lexxmark/winflexbison/releases/download/v2.5.22/win_flex_bison-2.5.22.zip
PS> Expand-Archive winflexbison.zip -Destination C:\WinFlexBison
PS> cp -Path C:\WinFlexBison\win_bison.exe C:\WinFlexBison\bison.exe
PS> cp -Path C:\WinFlexBison\win_flex.exe C:\WinFlexBison\flex.exe

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
PS> start git.exe

Compilation

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

Clone the source code of Fluent Bit.

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

Compile the source code.

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

Now you should be able to run Fluent Bit:

% .\bin\debug\fluent-bit.exe -i dummy -o stdout

Packaging

To create a ZIP package, call cpack as follows:

% cpack -G ZIP

PS> cp -Path C:\WinFlexBison\win_flex.exe C:\WinFlexBison\flex.exe

Add the path C:\WinFlexBison to your systems environment variable "Path". .

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

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
