Libvirt Java API to get CPU usage of VM (KVM)
Hi all libvirt-users,
Is there a counterpart on Java of the function virDomainGetCPUStats that is based on C API? Because I am trying to create a program based on
java to get the CPU usage of a Guest/Domain/VM in KVM using the Libvirt
Java API.
Honestly, I am having a hard time in starting my program. I have no
idea where to start. I mean, what functions do I need to get the CPU
usage of

how virt-manager gets CPU usage of Guest
Hi,
Does anybody know how virt-manager is getting the CPU usage of the guests? I need to know how to get the CPU usage of the guests and this is the only way I can think of. In other words, how does virt-manager produce the graph of the CPU usage of EACH guest in KVM? I don't actually need the graph, I just need to get the percentage(%) since I'm trying to create a Java program to get

getting CPU usage through virsh command or libvirt API
Hi,
Is it possible to get the CPU usage of a guest through a virsh command? I have tried almost all the commands (vcpuinfo, cpu-stats, etc.) that gets the details of a guest cpu, but it only returns the cpu time. Is there any command that returns the cpu usage (just like the graph that virt-manager displays) of a guest? Or do I have to create a program using libvirt API? Thanks in

problem when get the vm cpu stat
Hi all,
I try to get vm cpu stat by function "virDomainGetCPUStats", when the vm
Cpu usage is 100%, I can see from the vm shell by "top", when the info
Get by the "virDomainGetCPUStats" show only the "cpu_time" increased,
"user_time" and "system_time" was not changed at all.
Is that correct ? How can I get the vm cpu usage?

Qemu Hyperviser, this function returns something like this:

What features of kernel are required to support virDomainGetCPUStats?
Hi,
Weeks ago, I developed my app under ubuntu-11.10 (kernel 3.0) with
lilbvirt-0.9.10. In my code , I used virDomainGetCPUStats to query cpu
usage info of domains, and it worked well.
However, today, I port my code to ubuntu-10.04.4 (kernel 2.6.32) with
libvirt-0.9.10, I find the function virDomainGetCPUStats can't work
and complains "this function is not supported by the connection

Is there some tool or method in centos that can limit cpu usage to some percentage for specified processes that consume large cpu resource?
I found cpulimit which is only able to limit one process. what I want is one tool that can limit several same processes' cpu usage. Thanks!

CPU high usage

I am using Xapian 1.012 here, trying to optimise the search preformance.
My testing suit has 10M docs of forum threads,

After couple tests, I decided to remove ALL anchor terms such as

99% cpu usage help
I think the problem is that your icecast is wrong configured.
If it has an configuratrion error that dows not shut it down at startup,
it takes 99,9% cpu usage (thats my problem with, for example, a wrong path
to configuration file at startup, or something like this).
