Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

How do I point a Dockerized Grafana instance to the image renderer?

Add the rendering server URL and callback URL environment variables to the Grafana container. Point the rendering server URL to the renderer IP with the /render path and the callback URL to the Grafana IP, using your actual ports such as 8081 and 3000.

How can I inspect the image renderer server options when troubleshooting?

Run the image renderer Docker image with server --help to list the available options. These options are often the first ones to change during troubleshooting.

Can it render dashboards as PDFs?

It can render dashboards as PDFs and PNGs. CSV exports and email reports are only available with Grafana Enterprise.

Can it generate dashboard images for mobile widgets?

It has been used to create dashboard images for iOS widgets via Scriptable. The reported setup supported small, medium, and large widgets in dark and light modes.
