I am trying to send a simple value to a `zabbix` server.

Here is my configuration:

```
  zabbix {
    zabbix_host => "ip-resolvable-hostname-of-the-host-on-which-logstash-is-running"
    zabbix_server_host => "hostname-of-my-zabbix-server"
    zabbix_server_port => 10050
    zabbix_key => "[events_paloalto][rate_1m]"
    # zabbix_value => "[events_paloalto]][rate_1m]"
  }

```

(the above field does appear in my `elasticsearch`)

However in my `logstash` logs :

`[2019-01-31T12:01:08,696][WARN][logstash.outputs.zabbix] Field referenced by ip-resolvable-hostname-of-the-host-on-which-logstash-is-running is missing`

I have also tried to add in the `zabbix_key` field a value that just matches the `item` I am manually creating on my `zabbix` server (e.g. `somekeyname`) but I get the same error.
