Calculated item with item wildcards

[yoav]

Hi
Is there a way to specify multiple items with wildcards or something of the sort input for a calculated items. For example instead of:

last("net.if.in[eth0,bytes]")+last("net.if.out[eth0,bytes]")

do something like:

sum(last("net.if.in[eth*,bytes]"))

Then when ethX interface is added/removed from a machine (assuming an item is also added/removed respectively) we'll automatically have an updated calculated item for all the current network interfaces?

Calculated item with item wildcards

I am looking to do the same thing but in working with multiple filesystems.

Trying to get vfs.fs.size["/i13*,used"] to return back the information it has on 9 different file systems but whenever i create it the item becomes unsupported. Looking for anyway around this.
