Title: Aggregate Metrics for all Disks/Partitions

Show disk utilization and used/capacity cumulatively for all disks/partitions.

I noticed that only the used/size for / was shown, whereas I have /usr and /var as separate partitions, so I've just looped through the disk (historical) metrics to add all values from all partitions, instead of just the first disk object in the associative array.
