# overleaf-cep — Prometheus scrape config
# Modeled on the OlliTeX toolkit compose (reference: toolkit/compose.yaml +
# build-images/prometheus/prometheus.yml), adapted to THIS stack's container
# names. All targets are inside `overleaf-network` (Prometheus scrapes from
# inside the docker network; the nginx edge does not forward /metrics).

  # --- the Overleaf app itself ------------------------------------------------
  # The sharelatex image ships the @overleaf/metrics sensors on the web
  # process (libraries/metrics): num_active_users, timer_http_request
  # (summaries with quantiles), mongo_command_*, nodejs_* (event loop lag,
  # GC, heap), security_http_auth_check_credentials, editor_join_project,
  # tpds_add_doc, lock_mongoTransaction_*, ...
  # Verified live: 0.0.0.0:3000 inside the container, samples carry
  # app="web-api",host="overleaf". (Other in-image services e.g. compile
  # :4000 are 127.0.0.1-bound and therefore not network-scrapable.)
