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 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 iofileb.d +.PP +.SH FIELDS +.TP +PID +process ID +.TP +CMD +process name +.TP +KB +kilobytes of disk I/O +.TP +FILE +file pathname +.PP +.SH DOCUMENTATION +See the DTraceToolkit for further documentation under the +Docs directory.
