Port number in net.tcp.service check

[highpeak]

We have a number of devices behind a firewall where we need to check the web server is running. We've forwarded ports on the firewall to port 80 on each device. I know I can hard-code the port in net.tcp.service(http,,<port>) but we need to use the port specified in the host (as we have 3,000 devices and we provision via API). Without a template I would have to go to each host and create a unique item. Using {HOST.PORT} macro would make sense, but some some bizarre reason this is not supported. Suggestions?

Macro {#IF.PORT} of internal LLD rule zabbix[host,discovery,interfaces]

[highpeak]

I'm sorry, I'm not sure what you're suggesting. We don't run an LLD rule as these are IoT devices. So there's no agent running. Can you elaborate a little to help me out please?

You want to get the Zabbix host's interface port, aren't you? Internal LLD rule doesn't require the Zabbix agent on the host.

highpeak, how about defining your own macro for each host? Like {$HTTP_PORT}, and then using that in the template that you attach to the hosts?
