In our environment, we are collecting SAR files from Linux (SuSE-11/Redhat-5) servers and using ksar to generate graphs. The ksar graphs are put in the http doc root to be accessed via browser.

We have observed that the ksar utility does not show amount of CPU time spent on I/O wait in the graphs for any SUSE server. This is not an issue for the graphs generated for sar files of RHEL5 servers.

If you have come accross this issue, please comment or suggest.
