Previous thread title was
[PATCH 0/5 0/1 0/1 V3] Add new public API virDomainGetPcpusUsage() and pcpuinfo command in virsh
This is new version. As suggested in previous thread, this version impelements
virDomainGetCPUStats(), which uses virTypedParameterPtr as argument.
I wonder I've already missed the deadline. If this this version is not enough,
Lai-san will post v5. Someone may think the new API is complicated.
This patch set provides new virsh command, cpu-accts. This shows guest's cpu usage.
[root@bluextal ~]# virsh cpu-accts GuestX1
Total:
cpu_time 165.4
CPU0:
cpu_time 0.0
CPU1:
cpu_time 0.0
CPU2:
cpu_time 0.0
CPU3:
cpu_time 0.0
CPU4:
cpu_time 78.9
CPU5:
cpu_time 0.0
CPU6:
cpu_time 0.0
CPU7:
cpu_time 86.5
In this case, GuestX1 used 160sec of CPU and mainly using CPU5 and CPU7.
Changes:
- changed API design
- handle preset_cpu_map and max cpu id
- dropped Python API.
Note:
- This patch set doesn't include Python API etc..we'll prepare ones if
C APIs are finally fixed.
Thanks,
-Kame
