ICMP Monitor

The ICMP Monitor checks whether a host is reachable on the network. This is ideal for infrastructure components that do not expose HTTP endpoints (e.g. routers, firewalls, VPN gateways, databases, or internal services).

How it works

• We send ICMP echo requests (“ping”) to your hostname.
• The monitor is considered healthy when the target responds within the configured timeout.
• We record latency and detect sustained reachability problems.

Configuration

Basic settings

• Name: A human-friendly label.
• Hostname: Hostname or IP address (no protocol, no path).
• Check interval: How often to check.
• Timeout: How long to wait for a response.
• Status:
  • active: checks run normally.
  • maintenance: checks still run, but alerting may be dampened depending on alert logic.
  • disabled: checks do not run.

Monitoring locations

ICMP checks run from our monitoring locations.

• If you set Allowed Check Countries on the monitor, checks run only from matching locations.
• If the monitor has no restrictions, (if configured) the customer-level allowed countries apply.
