In the documentation, the item simple check, is described in the key net.tcp.service [service, <ip>, <port>], however if I use net.tcp.service [https] and the port is 443, OK returns me 1, but if the port is for example 58091 and I use the net.tcp.service [https ,, 58091] key, it returns 0.
But in the documentation it says that I can use an alternative port.

I did the same test on port 80 and 58081 http and it worked.

Using net.tcp.service [tcp ,, 58091] returns 1 too, because Using net.tcp.service [https ,, 58091] returns 0?

Examples of using simple checks in the documentation:

net.tcp.service [ftp ,, 155]
net.tcp.service [http]
net.tcp.service.perf [http ,, 8080]
net.udp.service.perf [ntp]
