Ping Monitor

Checks host reachability via TCP connection. Used to verify that servers and network devices are responding.

Configuration

Field	Description	Required	Default
Hostname	Target hostname	Yes	-
Port	Port number to connect to (1-65535)	No	443
Timeout	Maximum time to wait for a connection	No	10 seconds

The timeout can be set between 1 second and 30 seconds.

Tip

If no port is specified, the default is 443 (HTTPS). If you need to monitor a specific service port, consider using a TCP monitor instead.

Difference from TCP Monitor

	Ping Monitor	TCP Monitor
Purpose	Host reachability check	Specific service uptime monitoring
Port	Optional (default 443)	Required
Use Case	Server connectivity, network monitoring	Database, mail server monitoring

Common Use Cases

• Web server connectivity check (when HTTP checking is unnecessary)
• Network device (routers, switches) reachability check
• External service availability verification

Incident Detection

A failure is detected when any of the following conditions are met:

• TCP connection was refused
• Connection timed out
• DNS resolution failed

Note

Connections to private IP addresses and localhost are blocked as an SSRF countermeasure.
