Description Frank Hirtz 2001-11-09 21:29:43 UTC 
Description of Problem:
The iostat manpage says, in the BUGS section: 

Statistics in KB/s for each block device are not available by  default  due
 to Linux poor disk accounting.  For the   same reason,  a  kernel  patch 
need to be  applied  for extended statistics to be displayed.

Our performance tuning group only has tools to analyze system performance
in KB/s, not sectors/s.  What is the procedure for enabling this (the man
page says it's not available "by default" which means it should be
available by some mechanism)?

So the request is?
Comment 2 Frank Hirtz 2001-12-11 22:05:33 UTC 
It's a Morgan Stanley feature request. They'd like to have this ability added.
Comment 3 Trond Eivind Glomsrxd 2001-12-12 20:16:30 UTC 
The extended information patch is part of the kernel, and the information has
been removed from the man page to avoid confusion.
Comment 4 Trond Eivind Glomsrxd 2002-02-28 23:21:16 UTC 
sysstat-4.0.3-1 from http://people.redhat.com/teg/sysstat/ has this capability.
