To implement custom JavaScript code in Grafana, you can use Grafana plugins or create a custom panel with your own JavaScript code.
Grafana plugins allow you to easily add new features and functionality to your Grafana instance by adding custom code written in JavaScript. You can create your own plugins or use existing open-source plugins available in the Grafana plugin repository.
Alternatively, if you want more control over the JavaScript code, you can create a custom panel in Grafana. This allows you to define your own panel type and write custom JavaScript code to render the panel as you desire.
To create a custom panel, you will need to define a new panel type in Grafana and write JavaScript code to handle the data visualization and interaction logic. You can then add your custom panel to your Grafana dashboard and use it to display your data in a unique way.
Overall, implementing custom JavaScript code in Grafana gives you the flexibility to extend the capabilities of Grafana and create custom visualizations and dashboards tailored to your specific needs.

How do I include external JavaScript libraries in Grafana?
To include external JavaScript libraries in Grafana, you can follow these steps:
- Download the JavaScript library that you want to include in your Grafana dashboard.
- Upload the JavaScript library file to a web server or any accessible location.
- In your Grafana dashboard, go to the "Dashboard settings" by clicking on the gear icon in the top right corner.
- Under the "General" tab, scroll down to the "Scripted dashboard options" section.
- In the "Script libraries" field, enter the URL of the external JavaScript library file that you uploaded in step 2.
- Click on "Save" to apply the changes.
Now, the external JavaScript library should be included in your Grafana dashboard, and you can use it to enhance the functionality of your dashboard.
How to customize visualization components with JavaScript in Grafana?
To customize visualization components with JavaScript in Grafana, you can use the built-in Grafana plugin system which allows you to create custom visualization plugins. Here are the steps to customize visualization components with JavaScript in Grafana:
- Create a new plugin: Create a new folder under the Grafana plugins directory (usually located at /var/lib/grafana/plugins/) and create a new plugin.json file inside the new folder. The plugin.json file should contain metadata about your plugin, such as the name and description.
- Write the JavaScript code for your custom visualization: Create a new JavaScript file inside the plugin folder that defines the logic for your custom visualization. You can use libraries like D3.js or Plotly.js to create custom visualizations. Make sure to follow the Grafana visualization plugin API guidelines when writing your JavaScript code.
- Register the visualization plugin: You need to register your custom visualization plugin with Grafana so that it appears in the list of available visualizations. To do this, update the plugin.json file with the necessary metadata to register your visualization plugin.
- Test the visualization: Once you have created your custom visualization plugin, restart Grafana to load the plugin. You should now see your custom visualization in the visualization panel in Grafana. You can test your visualization by adding it to a dashboard and configuring it with data from a data source.
- Customize the visualization: To further customize your visualization, you can modify the JavaScript code to add interactivity, custom styling, or additional features. You can also use Grafana's APIs to access and manipulate data from the data source.
By following these steps, you can create and customize visualization components with JavaScript in Grafana to create unique and interactive visualizations for your dashboards.
How do I write custom JavaScript functions for Grafana?
To write custom JavaScript functions for Grafana, you can create a new plugin or modify an existing one. Here are the steps to create custom JavaScript functions for Grafana:
- Create a new plugin or use an existing plugin: You can create a new plugin by following the Grafana plugin development guide (https://grafana.com/docs/grafana/latest/developers/plugins/). If you have an existing plugin that you want to modify, you can use that as a starting point.
- Define your custom JavaScript functions: Once you have your plugin set up, you can write your custom JavaScript functions in the plugin's codebase. You can create new functions within the plugin's JavaScript files or create a new file specifically for your custom functions.
- Register your custom functions with Grafana: To make your custom JavaScript functions available in Grafana, you need to register them with Grafana. This typically involves adding your functions to the plugin's main file and exporting them as part of the plugin's module.
- Test and debug your custom functions: Before using your custom JavaScript functions in Grafana dashboards, make sure to test and debug them thoroughly. You can use Grafana's built-in logging and debugging tools to troubleshoot any issues.
- Use your custom functions in Grafana dashboards: Once your custom JavaScript functions are working correctly, you can use them in Grafana dashboards by calling them within your dashboard's panel configuration. You can pass parameters to your functions and use their return values to customize the behavior of your panels.
By following these steps, you can create custom JavaScript functions for Grafana and extend its functionality to meet your specific requirements.
What are some common use cases for custom JavaScript in Grafana?
- Creating dynamic dashboards: Using custom JavaScript, you can create dynamic dashboards that display real-time or customized data based on user interactions.
- Custom data visualization: You can use custom JavaScript to create custom data visualizations that are not available out of the box in Grafana.
- Integration with external services: You can use custom JavaScript to integrate Grafana with external services, such as APIs or databases, to fetch and display data in your dashboards.
- Custom data manipulation: You can use custom JavaScript to manipulate and transform data before displaying it in your dashboards.
- Custom alerting mechanisms: You can use custom JavaScript to create custom alerting mechanisms that notify users based on specific conditions or thresholds.
- Customizing and extending Grafana functionalities: You can use custom JavaScript to customize and extend the functionalities of Grafana, such as adding new features or enhancing existing ones.
