seeksize.d - print disk event seek report. Uses DTrace.
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 users with root privileges can run this command.
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.
seeksize.d will sample until Ctrl-C is hit.
