How to show data rate/bandwidth in Zabbix maps?

[skyflayx]

I have 0 experience in Zabbix and I have no coding skills and experience whatsoever.

I tried searching/looking using this exact question but it only leads me to posts from 2014, and there are no exact steps on how to do so so I am completely lost.

My goal is, in Zabbix maps, to show the bandwidth on the links between our main firewall and branch firewalls. I have found that I have to create items on the firewalls first but I always get this problem.

What should I do and how should I proceed?

But it clearly says there... "no interface found" You host has no agent interface defined, but you are trying to use agent item... Define the interface and then fill item parameters with correct values (if-> your interface name, <mode> -> required mode)

net.if.in[if,<mode>]
Incoming traffic statistics on network interface.	Integer	if - network interface name (Unix); network interface full description or IPv4 address; or, if in braces, network interface GUID (Windows) mode - possible values: bytes - number of bytes (default) packets - number of packets errors - number of errors dropped - number of dropped packets overruns (fifo) - the number of FIFO buffer errors frame - the number of packet framing errors compressed - the number of compressed packets received by the device driver multicast - the number of multicast frames received by the device driver
