Hi All,
In order to support NUMA and guest NUMA feature in ovirt.
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.
Best Regards,

Subject: Supposed to add per CPU usage related infomation into engine core and vdsm
Hi All,
In order to support NUMA and guest NUMA feature in ovirt.
We need per NUMA node CPU usage or per CPU usage related information on
engine core.
This information will be used for VM who have NUMA aware information and find
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,
%idle)
3. Transport the usage data to engine core.
4. Engine core merge per NUMA node CPU usage. (%sys, %usr, %iowait,
%idle)
+1, since this data can be used for hardware other than NUMA
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,
%idle)
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.

+1, since this data can be used for hardware other than NUMA
+1 , can be relevant to engine reports as well ....
