Fluent Bit

Fluent Bit configuration
HTTP output plugin allows flushing your records into an HTTP endpoint. The HTTP output plugin allows to provide interoperability between compatible systems, Logiq being one.
The below code block defines the minimal changes to be added to the fluent-bit configuration using the HTTP plugin to start sending log events to flash.The below config supports storage persistence.

Fluent Bit for Windows
You can use Fluent Bit to ship Windows logs to LOGIQ by leveraging the following Fluent Bit configuration.
The instruction to install fluent-bit for windows is available at the following git repository - https://github.com/logiqai/logiq-installation/tree/main/fluent-bit/windows​
The folder in the git repository includes a PowerShell script to set up the windows fluent-bit agent. The PowerShell script downloads the fluent-bit agent and installs the agent as a service. Continue below to see how to set up an example fluent conf and start service on windows.
NOTE: You will need to finalize the fluent configuration and then restart the service. Below is an example of fluent configuration
[SERVICE]
    Flush           1
    Daemon          yes
    Log_Level       info
​
​
[FILTER]
    Name          record_modifier
    Match         *
    Record namespace Windows 
​
[FILTER]
    Name modify
    Match *
    Rename SourceName AppName
    Rename ComputerName Hostname

[INPUT]
    Name                   winlog
    Channels               Setup,Windows PowerShell,Security
    Tag                    Windows-events
    Interval_Sec           5

[OUTPUT]
    name                   http
    match                  *
    host                   Logiq-Hostname
    port                   443
    URI                    /v1/json_batch
    Format                 json
    tls                    on
    tls.verify             off
    net.keepalive          off
    compress               gzip
    Header Authorization Bearer <token>
To forward Windows logs to LOGIQ using Fluent Bit, do the following. 
1.Copy the configuration provided above and save it locally in a temporary folder. 
2.Edit the fields in the [OUTPUT] section of the configuration file to match your LOGIQ instance. 
3.Clone the LOGIQ installation GitHub repository locally and navigate to the windows folder.
4.Copy and paste the fluent-install.ps1 script into the folder where you saved the Fluent Bit configuration file. 
5.Since Windows does not allow you to execute scripts due to default PowerShell script execution policies, you should update the set execution policy by running: 
Set-ExecutionPolicy unrestricted
6.Navigate to Windows > PowerShell and run it in Administrator mode. 
7.Execute the fluent-install.ps1 script, as shown in the following example:
PS D:\test> .\fluentbit-install.ps1
[SC] CreateService SUCCESS
The fluent-bit service is starting.
The fluent-bit service was started successfully.
8.Navigate to Windows > Run.  
9.Type services.msc and hit Enter. 
You'll now see a Fluent Bit service running on your Windows machine. 
OR
You can also run the .\status.ps1 helper scripts present at https://github.com/logiqai/logiq-installation/tree/main/fluent-bit/windows/helper-scripts​
We have scripts to: 
Restart Fluent-Bit service.
Start Fluent-Bit service.
Status of fluent-Bit service.
Stop Fluent-Bit service.
Uninstall Fluent-Bit service.
