MQTT item has status "Not supported"

[admin@hilton]

I have created a MQTT Item:

on a host that has an agent interface `127.0.0.1` on port 10051.

On my zabbix server `127.0.0.1` a zabbix-agent2 is running where Server and ServerActive is set to 127.0.0.1.

The problem is that the item is still has the status "Not supported" but I don't understand why. The info say it does not support tests (I don't do that) or single passive check mode (I use an active zabbix agent). So what is the problem?



Edit: There is an existing "Zabbix Server" host that uses the same agent interface. If I add the item there everything works. So I can only have one host per zabbix-agent?

I solved this problem.

Per agent you can only have one host by default, but you can edit the `Hostname` in zabbix_agent2.conf to a list of hosts. So alter changing this line to
```
Hostname=Zabbix server,Fitness Room ESP
```
and restarting the agent, everything worked as expected.


Maybe the error message could be more helpful...
