Linux pmda reports less disk IO stats for disk.partitions comparing to disk.dev and disk.dm. Added the following metrics which are currently missing for kernel 2.6.25 and above:
disk.partitions.read_merge
disk.partitions.write_merge
disk.partitions.avactive
disk.partitions.aveq
disk.partitions.read_rawactive
disk.partitions.write_rawactive
