Atm, we do not check how old the JSON file is, nor do we export its age. Both could be useful to detect half-process failures (teh NL process exiting, or there being a permission issue for it).

Things we should do:

  • export the JSON file's ctime
  • maybe allow the user to say that the webserver should exit if the JSON file is older than $DURATION, making staleness very obvious on the Prometheus side.
