Health
Liveness, uptime and a one-line feed summary.
GET
/health entities is the sum of vehicles, trip updates and alerts currently loaded — if it reads 0, the data directory failed to load and every other endpoint will be empty. uptime is the server process's, in seconds, and says nothing about how fresh the data is; for that, read feedTimestamp.
