Alerts

For Discord, Slack, Telegram, Teams, email, WhatsApp and routing events to channels, see Notifications; this page covers what the gateway watches for.

Off unless you set NOTIFY_URL. Then the gateway watches for things worth a message and sends at most one alert per kind per cooldown.

export NOTIFY_URL=https://ntfy.sh/your-secret-topic     # or any webhook that takes JSON
wms-go notify test

For the gateway service, put it in /etc/wms-go/wms-go.env (see config.example.env). ntfy is used when the host contains "ntfy", otherwise a JSON webhook ({title, message, priority, text, content}, readable by Slack and Discord); force it with NOTIFY_FORMAT=ntfy|json.

Alert	When
Failed sign-ins	10 or more in 10 minutes
Audit log changed	the hash chain is broken (highest priority)
Backup stale	none, or the newest is over 7 days old
Low stock	parts below their minimum (daily)
Price drop	a watch is at its limit (daily)
Audit head	the chain's newest hash, once a day: your off-machine copy

Messages never contain passwords, tokens or 2FA codes. Connection errors don't repeat the URL (it may hold a secret topic).
