Ready to dive into the world of Grafana Alloy on your Windows machine? Awesome! This guide will walk you through the entire process, making it super easy to get up and running. We'll cover everything from downloading the necessary files to configuring Alloy to collect and forward your metrics, logs, and traces. So, let's get started!

Prerequisites

Before we jump into the installation, let's make sure you have everything you need:

  • A Windows machine: This guide is tailored for Windows users, so you'll need a computer running Windows 10 or later.
  • Basic command-line knowledge: We'll be using the command prompt (or PowerShell), so a little familiarity will be helpful.
  • A text editor: You'll need a text editor to configure Alloy. Notepad, Notepad++, VS Code, or any other editor will work.

Downloading Grafana Alloy

First things first, you need to download the Grafana Alloy binary for Windows. Here's how:

  1. Head to the Grafana Alloy releases page: Go to the official Grafana Alloy GitHub releases page. You can find it by searching "Grafana Alloy GitHub" on your favorite search engine. Make sure you are on the official Grafana repository to avoid any security risks.
  2. Find the latest release: Look for the most recent release. It's usually at the top of the page and clearly labeled.
  3. Download the Windows binary: Scroll down to the "Assets" section of the release. Look for a file that ends with windows-amd64.zip. This is the Windows version of Alloy. Download it to your computer.
  4. Extract the ZIP file: Once the download is complete, extract the contents of the ZIP file to a directory of your choice. A good place would be C:\Program Files\Alloy or any other location you prefer. Just make sure you remember where you put it!

Configuring Grafana Alloy

Now that you have Alloy downloaded, it's time to configure it. Alloy uses a configuration file to tell it what to do. Let's create a basic configuration file.

  1. Create a new file: Open your text editor and create a new file. Save it as alloy. River in the same directory where you extracted the Alloy binary (e.g., C:\Program Files\Alloy). The .River extension is important because it tells Alloy that this is its configuration file.

  2. Add basic configuration: Paste the following configuration into the alloy.River file:

    local.file_match "system_logs" {
  path_patterns = [
    "C:/ProgramData/Microsoft/Windows/EventData/*.evtx",
  ]
  output = [stdout.write.input]
}

stdout.write "write" {
  format = "json"
  input  = local.file_match.system_logs.output
}

logging.level {
  level = "info"
}

    This simple configuration does the following:

    • local.file_match: This component finds all .evtx files (Windows event logs) in the specified directory.
    • stdout.write: This component writes the logs to the standard output (your console).
    • logging.level: This component sets the logging level to info, to have more verbose output, set the level to debug.

    Feel free to modify the path_patterns to match the location of your log files. You can add multiple patterns to collect logs from different locations.

  3. Save the file: Save the alloy.River file. Make sure it's saved as a plain text file with the .River extension.

Running Grafana Alloy

With Alloy downloaded and configured, it's time to run it! Here's how:

  1. Open Command Prompt (or PowerShell): Open the command prompt by searching for "cmd" in the Windows search bar. Alternatively, you can use PowerShell.

  2. Navigate to the Alloy directory: Use the cd command to navigate to the directory where you extracted the Alloy binary and saved the alloy.River file. For example:

    cd "C:\Program Files\Alloy"

  3. Run Alloy: Execute the following command to start Alloy:

    .\alloy.exe -config=alloy.River

    This command tells Alloy to use the alloy.River file for its configuration.

  4. Observe the output: If everything is configured correctly, you should see Alloy start up and begin printing log data to the console. The output will be in JSON format, as specified in your configuration file.

Understanding the Output

The output you see in the console is the log data that Alloy is collecting and processing. Each line represents a log entry, and it's formatted as a JSON object. You can customize the format of the output by modifying the stdout.write component in your alloy.River file. For example, you can change the format to logfmt for a more human-readable output.

Installing Alloy as a Windows Service

Running Alloy from the command line is fine for testing, but for production use, it's better to install it as a Windows service. This will ensure that Alloy starts automatically when your computer boots up and that it keeps running in the background.

Using NSSM (Non-Sucking Service Manager)

One popular way to install Alloy as a Windows service is to use NSSM (Non-Sucking Service Manager). NSSM is a free and open-source tool that makes it easy to create Windows services from any executable.

  1. Download NSSM: Download the latest version of NSSM from its official website. Make sure to download the correct version for your system architecture (32-bit or 64-bit).

  2. Extract NSSM: Extract the contents of the ZIP file to a directory of your choice. A good place would be C:\Program Files\NSSM.

  3. Open Command Prompt as Administrator: Open the command prompt as an administrator. You can do this by right-clicking on the Command Prompt icon and selecting "Run as administrator."

  4. Navigate to the NSSM directory: Use the cd command to navigate to the directory where you extracted NSSM (e.g., C:\Program Files\NSSM).

  5. Install Alloy as a service: Execute the following command to install Alloy as a service:

    nssm install GrafanaAlloy

    This will open the NSSM service installer.

  6. Configure the service: In the NSSM service installer, configure the following settings:

    • Path: The path to the Alloy executable (e.g., C:\Program Files\Alloy\alloy.exe).
    • Startup directory: The directory where the Alloy executable is located (e.g., C:\Program Files\Alloy).
    • Arguments: -config=alloy.River

  7. Click "Install service": Click the "Install service" button to install Alloy as a Windows service.

  8. Start the service: Open the Services application (search for "Services" in the Windows search bar). Find the "GrafanaAlloy" service in the list. Right-click on it and select "Start" to start the service.

Configuring Service Recovery Options

To ensure that Alloy continues to run even if it crashes, it's a good idea to configure the service recovery options. This tells Windows what to do if the service fails.

  1. Open the Services application: Open the Services application (search for "Services" in the Windows search bar).

  2. Find the GrafanaAlloy service: Find the "GrafanaAlloy" service in the list.

  3. Open the service properties: Right-click on the "GrafanaAlloy" service and select "Properties."

  4. Go to the "Recovery" tab: Click on the "Recovery" tab.

  5. Configure the recovery options: Configure the recovery options as follows:

    • First failure: Restart the Service
    • Second failure: Restart the Service
    • Subsequent failures: Restart the Service

  6. Click "Apply" and "OK": Click the "Apply" button and then the "OK" button to save the changes.

Troubleshooting

If you run into any problems during the installation or configuration process, here are a few things to check:

  • Check the Alloy logs: Alloy writes logs to the console and to a file (if configured). Check the logs for any error messages or warnings.
  • Verify the configuration file: Make sure your alloy.River file is correctly formatted and that all the paths are correct.
  • Check the permissions: Make sure the user account that Alloy is running under has the necessary permissions to access the log files.
  • Consult the Grafana Alloy documentation: The official Grafana Alloy documentation is a great resource for troubleshooting and finding answers to common questions.
