<h2 id="step-1">Step 1: Installing and Configuring Grafana</h2>

<p>Grafana is a popular open-source platform for visualizing metrics. Follow these steps to install and configure Grafana:</p>

<ol>
<li><b>Download Grafana:</b> Download the Grafana installer for Windows from the official website.</li>
<li><b>Run the Installer:</b> Execute the downloaded installer.  When prompted about Windows security, click "Run Anyway".</li>
<li><b>Installation Directory:</b> Choose the installation directory (e.g., <code>C:\Program Files\GrafanaLabs</code>) for easier access. Accept any additional prompts.</li>
<li><b>Open Grafana:</b> Navigate to the installed directory, locate and open the "conf" folder.</li>
<li><b>Edit the "defaults" file:</b> Open the "defaults" file in a text editor (like Notepad).  If you encounter a permission error, right-click the "GrafanaLabs" folder in File Explorer, select "Properties," "Security," "Edit," "Users," check the "Full Control" box, and click "Apply."</li>
<li><b>Enable SMTP:</b> Locate the "enabled = false" line related to SMTP settings. Change it to "enabled = true."  Save the file.</li>
<li><b>Configure HTTP Port:</b> Find and adjust the `http_port = 3000` line (if needed) to a desired port number. Save the file.</li>
<li><b>Access Grafana:</b> Open your web browser and navigate to <code>localhost:3000/login</code>. Use the default username and password: "admin".  Set a new password immediately for security.</li>
</ol>

<h2 id="step-2">Step 2: Installing and Configuring Prometheus</h2>

<p>Prometheus collects metrics.  Follow these steps:</p>
<ol>
<li><b>Download Prometheus:</b> Download the Prometheus binary from the official website.</li>
<li><b>Extract to Program Files:</b> Extract the downloaded Prometheus file into your program files folder. (e.g., <code>C:\Program Files</code>). Do this in a simple way, not involving nssm.</li>
<li><b>Install Prometheus using NSSM:</b>
   <ol>
       <li>Download the latest NSSM release for Windows.</li>
       <li>Extract NSSM to the same Program Files directory as Prometheus.</li>
       <li>Open an elevated Command Prompt (cmd). Navigate to the NSSM directory.</li>
       <li>Use the command  <code>nssm install prometheus "C:\Program Files\Prometheus\prometheus"</code> replacing `C:\Program Files\Prometheus\prometheus` with the correct path to your Prometheus executable.  (Use the `nssm install prometheus` command and provide the path to your `prometheus` executable within the Program Files folder.)</li>
   </ol>
</li>
<li><b>Start Prometheus:</b> Use the `nssm start prometheus` command from the command prompt to start the Prometheus service.</li>
<li><b>Verify Prometheus:</b> Open a web browser and navigate to `localhost:9090`.  You should see the Prometheus interface.</li>
</ol>

<h2 id="step-3">Step 3: Installing and Configuring OhmGraphite</h2>

<p>OhmGraphite is the tool to gather data from your laptop hardware.</p>
<ol>
<li><b>Download OhmGraphite:</b> Download the OhmGraphite executable from the project repository or official website.</li>
<li><b>Extract Files:</b> Extract the downloaded files to a new folder named "OhmGraphite" within your Program Files directory.</li>
<li><b>Configure OhmGraphite:</b> Open the configuration file (likely `OhmGraphite.exe.config`) for editing.  **Crucially, use the correct configuration file for your specific version and obtain the latest recommended settings from the OhmGraphite GitHub repository**</li>
<li><b>Start OhmGraphite:</b> Use PowerShell to execute OhmGraphite, navigating to the "OhmGraphite" directory and running the executable. (e.g., <code>.\OhmGraphite.exe</code>).  Use administrator privileges.</li>
<li><b>Verify Metrics:</b> Check if metrics are being sent to `http://localhost:4445/metrics`. You should see your CPU and GPU information.</li>
</ol>

<h2 id="integrating">Integrating OhmGraphite with Prometheus</h2>

<p>Configure Prometheus to scrape metrics from OhmGraphite.  Using the right YAML structure is essential. Obtain the latest Prometheus configuration from the OhmGraphite project's repository and adjust as needed, making sure the `localhost` port matches your OhmGraphite setup.</p>

<ol>
<li><b>Edit Prometheus Configuration:</b>  Open the Prometheus configuration file (usually a YAML file). Add the following section (replacing `localhost` and `4445` with your actual values) to tell Prometheus where to find the metrics.  Make sure that this is after the last section.</li>

<pre>
  - job_name: 'OhmGraphite'
    static_configs:
    - targets: ['localhost:4445']
</pre>

<li><b>Restart Prometheus:</b>  Restart the Prometheus service to apply the changes.</li>
<li><b>Verify Connection:</b> Check the Prometheus interface (`localhost:9090`) to ensure that OhmGraphite appears in the "Targets" section. If it's not working, double-check your settings and configuration files.</li>
</ol>


<h2 id="visualizing">Visualizing Prometheus Data in Grafana</h2>

<ol>
<li><b>Add a Prometheus Data Source in Grafana:</b> In Grafana, create a new data source. Select "Prometheus," and input the Prometheus server URL (`http://localhost:9090/`).</li>
<li><b>Import a Dashboard:</b> In Grafana, import a pre-built dashboard designed for monitoring hardware metrics. You can find suitable dashboards online or use the repository resources.</li>
<li><b>Select the Correct Data Source:</b> Choose the Prometheus data source you just added in your dashboard.</li>
<li><b>Visualize Metrics:</b> Customize the displayed metrics in the dashboard to your needs. Add graphs, alerts, and visualizations to monitor various hardware components.</li>
</ol>


<h2 id="conclusion">Conclusion</h2>

<p>Congratulations! You've successfully set up a complete hardware monitoring system for your gaming laptop.  This allows you to track key performance indicators and identify potential issues early, maintaining a healthy system. If issues occur, carefully review the configurations, especially for Prometheus.</p>

<p>Remember to consult the official documentation for the latest configuration details and best practices.</p>

<p>Further Enhancements:</p>

<ul>
<li>Customizable dashboards: Design dashboards tailored to your specific needs.</li>
<li>Alerting system: Configure alerts for potential issues, like high CPU or memory usage.</li>
<li>Data analysis: Use the collected data to optimize your system's performance.</li>
</ul>

<p>If you encounter any further problems, please don't hesitate to ask for assistance. Thoroughly checking your configurations is critical to a smooth setup.</p>
