Checking also non-http(s) services

[thomasmerz]

Hi @AnandChowdhary , I really fell in love with this project! ❤️
I really would appreciate to have the ability for checking non http(s) services as well. For example:

Is anything listening on port xyz on host/IP (without result/returncode)?

$ tcping -t 1 8.8.8.8 53
8.8.8.8 port 53 open.

Good idea. I think tcp-ping can be used for this.

Support for pinging using tcp-ping has been added in @upptime/uptime-monitor@v1.25.1.

You'll need to add the property check: "tcp-ping" to use this:

sites: # List of endpoints to track
  - name: Google
    check: "tcp-ping"
    url: 46.28.246.123
    port: 80
