Is there a way to dynamically monitor filesystems on a server? How do you do that?

For the moment, when I had a new host, I run a script on it to check local FS and generate XML code ready to import into zabbix. However, if a new FS is created, it is not automaticaly added into zabbix (and I do not want to add a cronjob on each host to do that).

I tried to create un new parameter to send FS list to zabbix server, but I did not find a way to create a trigger who can treat these information. For example, it seems possible to change trigger state if a FS reach 95% but not to tell which one...

What is the best way to maintain node FS monitoring up to date without a manuel action? New FS are created everyday on serveral client, it is a real pain to add them manually into GUI...

Thank you in advance.
