- SITE_ROOT,PING_ENDPOINT: server address/port
- PING_EMAIL_DOMAIN: domain where healthchecks will receive alert e-mails
- SITE_NAME: name displayed on the healthchecks site

A sample nginx config file is included if you wish to proxy healthchecks.
The healthchecks database was created at /var/lib/healthchecks/hc.sqlite.
To run healthchecks, enable and start its systemd service and its weekly cleanup timer:
systemctl enable --now healthchecks
systemctl enable --now healthchecks-clean-db.timer
These processes will be run by the healthchecks user.
