  • haproxy_backend_server, the status of the backend server where values 0 and 1 represent, respectively, DOWN and UP. This metric has two additional fields: a state field that contains the state of the backend (either 'down' or 'up') and a server field that contains the hostname of the backend server.
  • haproxy_backend_session_current, the number of current sessions.
  • haproxy_backend_session_total, the cumulative number of sessions.
  • haproxy_backend_status, the global back-end status where values 0 and 1 represent, respectively, DOWN (all back ends are down) and UP (at least one back end is up).
