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, Is the array mstats returned by virDomainMemoryStats call cummulative or snapshot of the counter at that particular time ? I was of the opinion that is cummulative like the /proc counters but this counter seems to go backwards ie next snapshot value is less than the current one which makes me think these are snapshot values . I'm using RHEL 6.3...

I use like this; int n = virDomainMemoryStats(dom, stats, 4, 0); I want to get men used and not used. If can , I want to get all output in stats. but "n" result is always 0. ??????????????? -------------- next part -------------- An HTML attachment was scrubbed...

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...

...etInfo is equal to max memory with no virtio balloon driver set. When using virtio balloon driver and setting currentMemory less than memory in the xml, the used memory returned by virDomainGetInfo is nearly equal to currentMemroy. Again, I can't get the memory used by vm. 2. When I turned to virDomainMemoryStats, I can only get two values : Current balloon value and Resident Set Size of the process running the domain. (for kvm 0.14.1 and libvirt 1.0.2) That's not what I want. I only need to know how much memory used by the running vm, so I can calculate the memory usage of this vm. (like the used mem...

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: +33.(0)...

Hello, I'm trying to get memory usage statistic inside a guest machine using virDomainMemoryStats function at libvirt. According to http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatTags the structure could have a lot of useful memory statistic but the amount of parameters depends on the hypervisor and the driver. However using KVM I'm able to get VIR_DOMAIN_MEMORY_STAT_ACT...

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, virDomainMemoryStatPtr<http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatPtr>stats, unsigned int nr_stats, unsigned int flags). Problem is that it returns me just tags 0,6 and 7. Looking at the...

...following article on Redhat which suggests that this is normal/expected? https://access.redhat.com/solutions/2017943 Now we use following formula to calculate the memory utilization. mem_util = (rss/actual)*100 now this gives more that 100% as the result. We use the libvirt library to call the virDomainMemoryStats. (which is the same used by the "virsh dommemstat" command) If we can't use the RSS as the "used memory", what else should be used to calculate the same? What is the ideal approach to report memory utilization of guest from the KVM host?

Which OS are you using in your guests? Of course, you need to have the virtio balloon driver up and runnig in your guests. Claudio

I currently use following approach but its failing Find Max memory using following API         vdgiRet = virDomainGetInfo(domPtr, infoPtr);         memTotal = infoPtr->memory; Find current utilization using following API                 rVal = virDomainMemoryStats (domPtr, memStats, VIR_DOMAIN_MEMORY_STAT_NR, 0) ;         for (i = 0; i < rVal; i++)         {             if (memStats[i].tag == 7)                 memUsed = memStats[i].val;         } Which is the value of "VIR_DOMAIN_MEMORY_STAT_RSS    =    7" Then I calculate util as (memUsed...

...xplain 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 : VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON: active_balloon (1024000.000000) active_balloon (2048000.000000) VIR_DOMAIN_MEMORY_STAT_RSS: rss(1194195.312500) rss(2039269.531250 3) By using cgroup counters "memory.usage_in_bytes" for both Guests, I got these valu...
