+Multiple Zabbix servers
+^^^^^^^^^^^^^^^^^^^^^^^
+It is possible to instruct zabbix module to send data to multiple Zabbix servers.
+
+Parameter *zabbix_host* can be set with multiple hostnames separated by commas.
+Hosnames (or IP adderesses) can be followed by colon and port number. If a port
+number is not present module will use the port number defined in *zabbix_port*.
