TCP port monitoring for the services around the site
The website can be up while the mail server is not. A port check covers the services that have no web page.
Mail goes quiet before anyone complains.
When the SMTP server of a client stops, contact forms fail without an error and order confirmations never leave. People notice days later.
The same goes for an FTP server a supplier uses, or a database port that a second server needs.
A connection, on schedule.
Host and port
You enter a host name or a public IP and a port from 1 to 65535, for example mail.client.com and 587.
The check
At each interval we resolve the name, check that every address is public and open a TCP connection to it, with a 10 second limit.
Down and back up
A refused or timed-out connection is confirmed with a second attempt, then the alert opens. It closes when the port answers again.

Do you test the protocol, like a full SMTP conversation?
No. The check opens the TCP connection and closes it. It tells you the service is listening.
Can I monitor ping (ICMP)?
Not yet. Ping needs network permissions that we have not enabled on our servers.
