Monitoring % disk Space Free

[Buxton69]

I'm trying to monitor percentage disk space free but I'm getting a message saying 'not supported in Zabbix', the same calculation works for the trigger so I can set up triggers based on the % free space but cannot monitor it.

This is the calculation I have used:
vfs.fs.size[c:,free]/vfs.fs.size[c:,total]
custon multiplier: 100

I also tried:
vfs.fs.size[c:,free]/vfs.fs.size[c:,total]*100

This doesn't work.

In the trigger, which does work, I used:
{Template_Windows_New:vfs.fs.size[c:,free].last(0)}/{Template_Windows_New:vfs.fs.size[c:,total].last(0)}*100<10

Does anyone have a better calculation or know how to get the item to show in the template?

Thanks

Solved the issue, didn't realise that vfs.fs.size[c:,pfree] could be used to get the percentage free.
