Description=Onion Monero Blockchain Explorer Health Check Timer
# Deliberately NO `Requires=xmrblocks.service`. Requires on a timer stops the
# timer when the watched unit stops - "if the thing I am watching goes down,
# stop watching it" - leaving nothing to re-arm when it returns. Fulcrum's
# timer carried it and sat active+enabled for seven months without firing.

OnBootSec=2min
# Every 5 minutes (see xmrblocks_healthcheck_on_calendar). The check renders a
# full page out of the LMDB: 29s cold, 0.2s warm on NVMe - frequent polling is
# what keeps it warm. The Gatus heartbeat window is the standard 11m, set in
# infra/403_service_probe_registration.yml, and MUST stay above this interval.
OnCalendar={{ xmrblocks_healthcheck_on_calendar }}
# Small: a delay comparable to the interval would eat the heartbeat's slack.
