Re: [Zabbix-users] hostname addition automation

I think that such feature may introduce some serious security issues. Also,
it could add extra complexity to Zabbix configuration.

I see several ways of doing this.

1. You may access http://zabbix/~zabbix/hosts.php?host=newhost&newgroup=&useip=on&ip=127.0.0.1&port=10000&status=1&host_templateid=1&register=add
in order to add new host. So, a simple script consisting of many calls of "lynx <URL>" 
or "wget <URL>" may do the thing. This, however, requires Add Host permission for guest.

2. include/config.inc contains function add_host(). The function is self-explanatory and
can be safely used in your PHP scripts.

Thanks. Let me know if you need any help (configuration, performance tuning,etc).

By the way, having so many hosts, do you find PHP frontend usable? If not, what can be improved 
or changed?
