Heartbeat / cron monitor

Dead-man-switch. Ping us every N minutes — if you stop, we page.

What it checks

Gives you a secret URL. Your cron job, background worker, or scheduled task hits it on every successful run. If we haven't heard a ping within `expected_interval_sec + grace_sec`, an incident opens automatically.

When to use it

• Nightly database backups.
• Report-generation scripts.
• Queue workers (ping on each successful batch).
• Anything where silence is the failure mode.

Config fields

Fields marked * are required.

Example config

{
  "name": "nightly-backup cron",
  "type": "heartbeat",
  "config": {
    "expected_interval_sec": 86400,
    "grace_sec": 1800
  }
}

Notes

• The URL is shown once at monitor creation, hashed in the database, and cannot be recovered later.
• Accepts both GET and POST. Keep it secret — anyone who has it can mark your cron alive.
