No disk.partition information

[Patrick Aland <paland@xxxxxxxxxxx>]

Is there something special that has to be done to be able to view the 
disk.all.read_bytes and write_bytes (and disk.partition.read_bytes) doing a:

"pminfo -f disk.all" returns
disk.all.read
    value 1613136

disk.all.write
    value 2094781

disk.all.total
    value 3707917

disk.all.blkread
    value 12905022

disk.all.blkwrite
    value 16758248

disk.all.blktotal
    value 29663270

disk.all.read_bytes
No value(s) available!

disk.all.write_bytes
No value(s) available!

disk.all.total_bytes
No value(s) available!


(and similar for the .partition.*_bytes)

Thanks.
