prometheus/web/ui/README.md

The ui package contains static files and templates used in the web UI. For easier distribution they are statically compiled into the Prometheus binary using the go-bindata tool (c.f. Makefile).

During development it is more convenient to always use the files on disk to directly see changes without recompiling. To make this work, set the environment variable DEBUG=1, run make assets, and then make build.

This will put go-bindata in DEBUG mode where it serves from your local filesystem. This is for development purposes only.

After making changes to any file, run make assets (without the DEBUG=1) before committing to update the generated inline version of the file.
