We need per NUMA node CPU usage or per CPU usage related information on eng= ine core. This information will be used for VM who have NUMA aware information and fi= nd the best Host to run it on with best performance. Approach 1: 1. Sample data in vdsm for each CPU stats. (sys, usr, iowait, idle) 2. Calculate the each CPU usage information. (%sys, %usr, %iowait, %id= le) 3. Transport the usage data to engine core. 4. Engine core merge per NUMA node CPU usage. (%sys, %usr, %iowait, %i= dle) Approach 2: 1. Sample data in vdsm for each CPU stats. (sys, usr, iowait, idle) 2. Calculate the each CPU usage information. (%sys, %usr, %iowait, %id= le) 3. VDSM merge per NUMA node CPU usage. (%sys, %usr, %iowait, %idle) 4. Transport the usage data to engine core. Which one do you prefer, and why, or other solution.
