Uses DTrace. +.SH SYNOPSIS +.B seeksize.d +.SH DESCRIPTION +seeksize.d is a simple DTrace program to print a report of disk +event seeks by process. + +This can be used to identify whether processes are accessing the +disks in a "random" or "sequential" manner. Sequential is often +desirable, indicated by mostly zero length seeks. + +Since this uses DTrace, only the root user or users with the +dtrace_kernel privilege can run this command. +.SH OS +Solaris +.SH STABILITY +stable - needs the io provider. +.SH EXAMPLES +.TP +Sample until Ctrl\-C is hit then print report, +# +.B seeksize.d +.PP +.SH FIELDS +.TP +PID +process ID +.TP +CMD +command and argument list +.TP +value +distance in disk blocks (sectors) +.TP +count +number of I/O operations +.PP +.SH DOCUMENTATION +See the DTraceToolkit for further documentation under the +Docs directory.
