## Issue Addressed NA ## Proposed Changes - Adds a HTTP server to the VC which provides Prometheus metrics. - Moves the health metrics into the `lighthouse_metrics` crate so it can be shared between BN/VC. - Sprinkle some metrics around the VC. - Update the book to indicate that we now have VC metrics. - Shifts the "waiting for genesis" logic later in the `ProductionValidatorClient::new_from_cli` - This is worth attention during the review. ## Additional Info - ~~`clippy` has some new lints that are failing. I'll deal with that in another PR.~~
