1. Priority queue
?? What about CPU run queue? sar -q 5 5
2. Disk cache hit%
disk cache hit make sense only for storage based disks, the OS is not aware of that, you need to get this from the storage itself, try TPC, STOR2RRD or other storage perf tools
3. Page out rate
vmstat 5 5 (po metric), vmstat -s
4. Swap out rate
vmstat 5 5 (pi metric), vmstat -s
5. Memory queue
??? never heard about such metric, what it should be?
