Monitor websites, APIs and network services for availability
Monitors (HTTP / Ping / Port)
Monitors continuously check whether an address is reachable and alert you when something changes.
Website Monitor (HTTP/HTTPS)
Checks whether a URL responds with a successful HTTP status. Ideal for websites, REST APIs and webhooks.
What gets checked: HTTP status, response time, SSL certificate validity, response content (keyword check).
Ping Monitor
Sends an ICMP ping to a host and checks if it responds. Ideal for servers and network devices where you want to verify the host is online without an HTTP service.
Port Monitor (TCP)
Checks whether a specific port on a host is open. Examples:
- Port 22 (SSH) — check if SSH access is available
- Port 3306 (MySQL) — check if the database is reachable
- Port 25/587 (SMTP) — check the email server
Advanced settings
- Check interval: frequency (1 minute to several hours)
- Timeout: maximum wait time before marking as failure
- Ping servers: choose from which geographic regions to check
Incidents
When a monitor detects a failure, an incident is automatically created. Go to Incidents to see the full history with duration and resolution times.
