How to build a Grafana panel plugin from scratch?

Building a Grafana panel plugin from scratch involves the following steps:

  1. Set up the development environment: To build a Grafana panel plugin, you need to have Node.js, Yarn, and Grafana installed on your machine. Make sure to install the required versions as mentioned in the Grafana plugin development documentation.
  2. Initialize a new plugin: Open your terminal and navigate to the folder where you want to create the plugin. Run the command npx @grafana/toolkit plugin:create my-panel to create a new plugin called "my-panel". This will set up the basic structure of the plugin.
  3. Configure the plugin: Open the plugin.json file in your newly created plugin folder. Update the details like name, ID, version, and other necessary fields according to your requirements.
  4. Define panel options: Create a TypeScript file (src/module.ts) where you define the available options for your panel. These options include fields like text inputs, dropdowns, and more, which users can configure in the Grafana UI.
  5. Build your panel: Create a new TypeScript file (src/MyPanel.tsx) where you define the panel's behavior and rendering. You can import necessary dependencies, define React components, and set up hooks to handle the lifecycle of the panel.
  6. Create a visualization: Depending on the type of panel you want to create, you can use various charting libraries like D3.js, Highcharts, or Plotly to visualize the data. Install the required library using NPM or Yarn, and then import and use it in your MyPanel.tsx file.
  7. Build and test the plugin: Run yarn dev to build and watch your panel plugin. Open a web browser and go to your Grafana development instance, where you can navigate to the Plugins section and enable your newly built plugin. Create a new dashboard and add your panel to test its functionality and appearance.
  8. Package and distribute the plugin: Once your plugin is working correctly, you can create a distributable version by running yarn build in your terminal. This will create a dist/ folder with your plugin's bundled JavaScript files. You can distribute this folder to other Grafana users or publish it on the Grafana plugin repository.

Remember to refer to Grafana's official documentation, including the Panel Plugin Development guide and the plugin SDK, for more detailed information and comprehensive examples.

What are the security considerations while building Grafana panel plugins?

When building Grafana panel plugins, there are several security considerations to keep in mind:

  1. Authentication and authorization: Implement proper authentication mechanisms and ensure that only authorized users have access to sensitive data. Grafana has built-in authentication options such as LDAP, OAuth, and basic authentication.
  2. Input validation and output encoding: Thoroughly validate and sanitize all user inputs to prevent common web vulnerabilities such as Cross-Site Scripting (XSS) and SQL injection. Additionally, encode output data to prevent any unintended execution of scripts or malicious actions.
  3. Least privilege principle: Grant only the necessary permissions to your panel plugin. Make sure that it doesn't have excessive privileges that could potentially be exploited by attackers.
  4. Secure communication: Ensure that all communications between the Grafana server and your panel plugin are encrypted using protocols like HTTPS. This prevents eavesdropping and tampering of data transmitted.
  5. Secure storage of sensitive data: If your plugin requires storing sensitive information, such as API keys or credentials, make sure to use secure storage mechanisms like encrypted databases or environment variables. Avoid hardcoding sensitive data within the plugin code.
  6. Regular updates and security patches: Stay updated with the latest security fixes and updates from Grafana. Monitor their security advisories and promptly apply any necessary patches to your panel plugins.
  7. Penetration testing: Perform security testing on your panel plugin using techniques like penetration testing or vulnerability assessments. Identify and address any potential security weaknesses or vulnerabilities.
  8. Access controls: Implement proper access controls within your panel plugin to restrict access to sensitive features or data based on user roles or permissions.
  9. Secure dependencies: Ensure that you are using trusted and up-to-date dependencies in your panel plugin. Keep track of any security vulnerabilities reported in your dependencies and promptly patch or update them.
  10. Secure deployment: Follow secure deployment practices to protect your panel plugin from unauthorized tampering or modification. Use secure file permissions, secure hosting environments, and consider containerization for added security.

By following these security considerations, you can build panel plugins that are resilient against common security threats and help protect the integrity and confidentiality of your Grafana platform.

What are the available data transformation options in Grafana panel plugins?
