Description=Monero Node Health Check Timer
# Deliberately NO `Requires=monerod.service`. Requires on a timer stops the
# timer when the required unit stops - "if the thing I am watching goes down,
# stop watching it" - and leaves nothing to re-arm when the service returns.
# Fulcrum's timer carried it and sat active+enabled for seven months without
# firing once. bitcoin_knots' timer still carries it; do not copy that.

OnBootSec=2min
# Every 5 minutes (see monero_healthcheck_on_calendar). The cadence and the
# Gatus heartbeat window are ONE decision - the window MUST exceed this
# interval, and it is the standard 11m in
# infra/403_service_probe_registration.yml.
OnCalendar={{ monero_healthcheck_on_calendar }}
# Small: a delay comparable to the interval would eat the heartbeat's slack.
