1N/A * iofileb.d - I/O bytes by filename and process.
1N/A * Written using DTrace (Solaris 10 3/05).
1N/A *
1N/A * This prints a summary of requested disk activity by pathname,
1N/A * providing totals of the I/O events in bytes. It is a companion to the
1N/A * iofile.d script - which prints in terms of I/O wait time, not bytes.
1N/A * I/O wait time is a better metric for understanding performance issues.
1N/A * Both disk and NFS I/O are measured.

1N/A * USAGE: iofileb.d # wait several seconds, then hit Ctrl-C

1N/A * FIELDS:

1N/A * KB Kilobytes of disk I/O
1N/A * FILE Full pathname of the file
