[Xen-devel] Xen Performance metrics

[<Lu.YJ@xxxxxxxxxxxx>]

Hi everyone,

 

I am studying the Xen performance metrics.

My questions are if we can get the following metrics from Xen hypervisor interface / XEND API (XEN management API) or not ?

cpu.extra.summation, cpu.ready.summation,

disk.busResets.summation, disk.commandsAborted.summation, disk.queueLatency.average,

mem.active.average, mem.overhead.average

If no, plan to add them? or How to add them?

 

As I study, there are the following results about XEN performance metrics on the current XEN 4.1.0.

BTW, VMWARE hypervisor can get all the metrics below.

We can determine if the VM / host encounter the bottleneck issues using the performance metrics.

	Xen (hypervisor) interface	Xen enabled kernel (drivers like balloon, network / block backend, privcmd,…)	XEN (management) API (XEND API)	Libvirt API
CPU
1. cpu.extra.summation
2. cpu.ready.summation
3. cpu.usagemhz.average	v	x	V	V
disk
4. disk.busResets.summation
5.disk.commandsAborted.summation
6. disk.totalLatency.average
7. disk.queueLatency.average
Throughput: An average of 8. disk.read.average and 9. disk.write.average 10. disk throughput  = (disk.read.average + disk.write.average ) /2	x	v	V	V
memory
11. mem.active.average
12. mem.consumed.average	v	x	V	V
13. mem.overhead.average
Memory Swapping: 14. mem.swapin.average, 15. mem.swapout.average 16. mem.swapped.average	v	x	x	V
17.mem.vmmemctl.average(balloon)	x	v	x	V
network
18. net.received.average, 19. net.transmitted.average and 20. net.usage.average	x	v	V	V

 

 

Thanks.

YJ
