iofileb.d
iofileb.d(1m) USER COMMANDS iofileb.d(1m)
NAME
iofileb.d - I/O bytes by file and process. Uses DTrace.
SYNOPSIS
iofileb.d
DESCRIPTION
This prints a summary of requested disk activity by pathname, providing totals of the I/O events in bytes. It is a companion to the
iofile.d script - which prints in terms of I/O wait time, not bytes. I/O wait time is a better metric for understanding performance
issues. Both disk and NFS I/O are measured.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
Sample until Ctrl-C is hit then print report,
# iofileb.d
FIELDS
PID process ID
CMD process name
KB kilobytes of disk I/O
FILE file pathname
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
iofileb.d will sample until Ctrl-C is hit.
