Check servers that do not speak HTTP
Not everything has a health URL. A TCP monitor opens a connection to a host and port; a ping monitor sends ICMP ping and records the round-trip time.
Set it up
Two monitors for a mail server:
Type: TCP Host: mail.example.com Port: 465
Type: Ping Host: mail.example.comHow it checks.
- TCP: the connection must open within the timeout.
- Ping: ICMP round-trip time to the host.
- IPv4 and IPv6 can be checked separately, so you see which one fails.
- Private and internal addresses are checked from a private agent inside your network.
- The alert names the monitor and the error, such as a refused connection or a timeout.
TCP and ping: alert
The alert names the monitor and the error, such as a refused connection or a timeout.
Alerts go to email, Slack, Microsoft Teams, Discord, Telegram, PagerDuty or a webhook. Monitor types: TCP and ping
