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)? --MSDW request Version-Release number of selected component (if applicable): How Reproducible: Steps to Reproduce: 1. 2. 3. Actual Results: Expected Results: Additional Information:
So the request is?
It's a Morgan Stanley feature request. They'd like to have this ability added.
The extended information patch is part of the kernel, and the information has been removed from the man page to avoid confusion.
sysstat-4.0.3-1 from http://people.redhat.com/teg/sysstat/ has this capability.
