"...what would that show?..."

Average wait time the metric used to determine disk bottlenecks which have been made obsolete in modern SAN environments. (* except for local scsi O/S disk and this can't be helped. *)

Other disk metrics:
read cache >85%
write cache >50-60%
%WIO - Need to look this one up
