...irt. 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_ACTUAL_BALLOON and VIR_DOMAIN_MEMORY_STAT_RSS only. Am I right it is not possible to get additional info such as used/unused memory inside a guest machine in case of KVM?

...nt 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/memTotal) But the value of memUsed exceeds value of memTotal by small amount resulting in memUtil to be around 101 %. I understand that VIR_DOMAIN_MEMORY_STAT_RSS is Resident Set Size of the process running the domain. How do I Calculate the...

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, 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).1.47.17.20.49 .

Actually, you should get more stats when using the virtio balloon driver in your guests. E.g. the windows virtio driver supports these stats: SWAP_IN 0 /* Amount of memory swapped in */ SWAP_OUT 1 /* Amount of memory swapped...
