Hi everyone,
I am studying the Xen performance metrics.
My question is 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
