Early this morning our sar reports show that WIO on the system was over 50% for about an hour. We also had some users complain about response time problems during this time. Is there a way I can go back and check what disks were busy during this time (something like topas but for historical data)? (1 Reply)

ditroff
DITROFF(7) Miscellaneous Information Manual DITROFF(7)
NAME
ditroff - classical device independent roff
DESCRIPTION
The name ditroff once marked a development level of the troff text processing system. In actual roff(7) systems, the name troff is used as
a synonym for ditroff.
The first roff system was written by Joe Osanna around 1973. It supported only two output devices, the nroff program produced text ori-
ented tty output, while the troff program generated graphical output for exactly one output device, the Wang Graphic Systems CAT typeset-
ter.
In 1979, Brian Kernighan rewrote troff to support more devices by creating an intermediate output format for troff that can be fed into
postprocessor programs which actually do the printout on the device. Kernighan's version marks what is known as classical troff today. In
order to distinguish it from Osanna's original mono-device version, it was called ditroff (device independent troff) on some systems,
though this naming isn't mentioned in the classical documentation.
Today, any existing roff system is based on Kernighan's multi-device troff. The distinction between troff and ditroff isn't necessary any
longer, for each modern troff provides already the complete functionality of ditroff. On most systems, the name troff is used to denote
ditroff.
The easiest way to use ditroff is the GNU roff system, groff. The groff(1) program is a wrapper around (di)troff that automatically han-
dles postprocessing.
