Caching rendered images for identical requests can significantly reduce load and improve response times for frequently generated reports. The renderer operates as a headless Chrome instance, executing the dashboard rendering logic independently from the main Grafana server.
This separation of concerns allows Grafana instances to offload rendering tasks, preserving server resources for data visualization and user interaction. Performance Tuning and Scaling Rendering is a resource-intensive process that consumes CPU and memory.

It receives rendering requests, fetches the specific dashboard, and utilizes Chrome to draw the final output. This allows dashboard links to automatically generate image previews and enables the "Export as PNG" functionality directly within the Grafana UI.
