Hi Is it possible to get to the following wait times ? Any plans on adding them ? CPU wait time : Time the VM had to wait to get the processor. similarly : Disk I/O wait time : Swap I/O wait time : Network I/O : Network I/O for storage separately ? Page faults I am looking for measurements that would signify contention and would help administrators make decisions in addition to the utilization metrics.

All filesystem and page fault I/O waiting time is expressed in one "iowait" statistic, also in the CPU lines in /proc/stat. And yes, vmstat, top and sar know about this one, too. -- Politics is the struggle between those who want to make their country the best in the world, and those who believe it already is.
