Monitors

Monitor Types

HTTP

Checks a URL and verifies the HTTP status code matches the expected value (default 200).

• Target: full URL (e.g. https://example.com/health)
• Expected Status: HTTP status code to expect
• Keyword: optionally check if the response body contains (or doesn’t contain) a string

SSL

Checks the SSL certificate of a hostname and alerts before it expires.

• Target: hostname (e.g. example.com)
• SSL Warn Days: number of days before expiry to alert (default 30)

Heartbeat

Passive monitoring — your service pings Pong instead of Pong checking your service. Useful for cron jobs, background workers, and scheduled tasks.

• No target needed — Pong generates a unique ping URL
• If no ping is received within the interval, the monitor goes down

See Heartbeat Monitoring for details.

Assign alert contacts to a monitor to be notified on state changes. You can assign multiple contacts to a single monitor.
