Install Filebeat

To get started you will need to install filebeat. To do this you have two main options:

Choose the filebeat (opens in a new tab) ZIP file (Windows ZIP x86_64) or
Choose the Microsoft Software Installer MSI (opens in a new tab) file (Windows MSI x86_64 (beta))

To successfully install filebeat and set up the required Windows service you will need to have administrator access.

If you have chosen to download the zip file:

Extract the contents of the zip file into C:\Program Files.
Rename the extracted folder to filebeat
Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator).
From the PowerShell prompt, run the following commands to install filebeat as a Windows service:

cd 'C:\Program Files\filebeat'

.\install-service-filebeat.ps1

If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example:

PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-filebeat.ps1

For more information about Powershell execution policies see here (opens in a new tab).

If you have chosen to download the filebeat.msi file:

double-click on it and the relevant files will be downloaded.

At the end of the installation process you'll be given the option to open the folder where filebeat has been installed.

Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator).
From the PowerShell prompt, change directory to the location where filebeat was installed and run the following command to install filebeat as a Windows service:

.\install-service-filebeat.ps1

If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example:

PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-filebeat.ps1

For more information about Powershell execution policies see here (opens in a new tab).
