User regexp in items

[gergelyk3]

Hello all,
Have you any idea how to make the summary item where I collect tha all servers hard disk space (linux and windows too.)

I tried with these settings on Windows servers

grpsum["Windows_servers","vfs.fs.size[*,total]","last","0"]
grpsum["Windows_servers","vfs.fs.size[/,total]","last","0"]

Have you any solution to our problem?

Thank you
Gergely
