How could I monitor disk operations under CentOS 5?
The quote is from RHEL 6 release notes
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/6.0_Release_Notes/powermanagement.html
There are more details about diskdevstat and netdevstat here: http://goo.gl/pA8Yt
Since they depend on SystemTap, check this: http://sourceware.org/systemtap/wiki/SystemTapOnCentOS
I couldn't find the tuned-utils package for CentOS 5.x but, if there aren't huge changes to SystemTap in CentOS 6.x, you could try to download the scripts from their repository and try them: https://fedorahosted.org/tuned/
