I can create LLD graph's that will graph for each item discovered, but I can't create a graph all the discovered entries for a prototype item.
e.g. I discover 3 filesystems (/boot, / and /var, and have prototype items for used space and free space.
I can create a single graph which has used and free space for /usr
But I can't create a graph which has used space for /boot, / and /var all on the same graph.
