Re: [libvirt-users] Problem in getting memory statistics
I have another problem.
As in java bindings there is no way to obtain cpu stats I decided to use a
python script.
It gives me, for the guest domain, cpu time, system time and user time.
Now, what does it mean cpu time? I though that it could be the overall cpu
time given to this vm...but the sum doesn't add up: user_time+system_time
!= cpu_time.
As I would need to get a %cpu usage, like virt-manager does (so it IS
possible, and it IS in python), what operation do I need to do to make this
happen?

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...,
virDomainMemoryStatPtr<http://libvirt.org/html/libvirt-libvirt.html#vi...,
unsigned int nr_stats, unsigned int flags).
Problem is that it returns me just tags 0,6 and 7.
Looking at the documentation I see they are not what I am looking for...I
would rather need 4 (VIR_DOMAIN_MEMORY_STAT_UNUSED) and 5
(VIR_DOMAIN_MEMORY_STAT_AVAILABLE).
Is there a way to set them?
