seeksize.d(1m) USER COMMANDS seeksize.d(1m)
NAME
seeksize.d - print disk event seek report. Uses DTrace.
SYNOPSIS
seeksize.d
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 users with root privileges can run this command.
EXAMPLES
Sample until Ctrl-C is hit then print report,
# seeksize.d
FIELDS
PID process ID
CMD command and argument list
value distance in disk blocks (sectors)
count number of I/O operations
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
seeksize.d will sample until Ctrl-C is hit.
