Hi, In which libvirt version are these virDomainMemoryStats() counters handled ? VIR_DOMAIN_MEMORY_STAT_SWAP_OUT VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT VIR_DOMAIN_MEMORY_STAT_UNUSED VIR_DOMAIN_MEMORY_STAT_AVAILABLE Thanks. Regards, J.P.

Hi everybody, I'm using libvirt java api bindings for my thesis. I would like to know if there is a way to obtain live information about cpu and mem usage of a domain. Regards, Enrico De Maio Skype: enrico.de.maio Mobile: +39 338 205 3397

Then your problem is your libvirt is too old.

Hi, I'm using the API virDomainMemoryStats to fetch memory stats for a domain/guest on Fedora 16/RHEL 6.3 . I don't get these counters filled up VIR_DOMAIN_MEMORY_STAT_UNUSED, VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON,VIR_DOMAIN_MEMORY_STAT_AVAILABLE , VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT and VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT. The version of libvirt 0.9.11 on Fedora 16 . How to get all the

Hello, I need to get how much memory is used by a guest system, in order to implement some monitoring function which tells me if the system is overstressed. I am currently using java apis and the binding which was suggested to me was Domain.memoryStats(); This is a binding to int virDomainMemoryStats (virDomainPtr<http://libvirt.org/html/libvirt-libvirt.html#virDomainPtr>dom,

Hi, By using libvirt-1.2.8-16.el7_1.3.x86_64 , it looks like there are 3 virDomainMemoryStats tags available : VIR_DOMAIN_MEMORY_STAT_SWAP_IN VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON VIR_DOMAIN_MEMORY_STAT_RSS Is there a plan to add the other ones ? Meanwhile , do you know which metrics ovirt uses to display memory column value in the manager GUI ? Thx. J.P. Ribeauville P:

Hi, I'm wondering how to explain following metrics I got from libvirt, regarding memory stats for the two GUESTS running on my host. 1) virDomainGetXMLDesc() shows these values : memmax (1024000.000000) memcurrent(1024000.000000) memmax (2048000.000000) .memcurrent(2048000.000000) 2) As values returned by virDomainMemoryStats(), I got these values :
