Disk and Network Statistics for a Specific Interval
Hi,
virDomainInterfaceStats - This function returns network interface stats for
interfaces attached to the domain.
virDomainBlockStats- This function returns block device (disk) stats for
block devices attached to the domain.
Based on which time interval these function returns values.
Is it cumulative from the vms uptime..?
OR average ...?
How can I get the average statistics of Disk and

ts.plot and x axes customization
Dear List,
I would be pleased if someone can help me with the following issue:
I'm about to plot two time series in one plot via ts.plot which looks like:
ts.plot(series1, series2, main=main, xlab=xlab, ylab=ylab, col=c("green",
"red", "blue"), lwd=2)
The problem is, that R automatically sets the x axes labels in
5-year-intervalls. Every

data monitored by "virDomainBlockStats" API not consistent with ones reading from /proc/[pid]/io, and corrugated with /proc/diskstats
Hi, all.
While monitoring KVM VMs’ disk utilisation using libvirt API “virDomainBlockStats", I find that the results acquired is not consistent
with the value read from /proc/[vm_pid]/io(i only care about “rd_bytes" and “wr_bytes” fields). Since libvirt doesn’t support host level monitoring,
i have to calculate the host’s disk utilisation by reading from the /proc/diskstats file.

Re: data monitored by "virDomainBlockStats" API not consistent with ones reading from /proc/[pid]/io, and corrugated with /proc/diskstats
Just to clarify my problems:
For each KVM virtual machine, it is actually a process running on the host.
The $pid in "/proc/$pid/io" represents the VM process’s PID. All my work
is done on the host, not inside the VMs. Take the VM process’s pid is “pid”,
What the /proc/$pid/io records is io statistics of the VM from the host’s
perspective. I understand that qemu might do some I/O

xm top
Hello everybody!
I´d like to know where "xm top" gets its information from. I want to get
those informations (cpu-load, mem etc. from the domUs) and display them
with php in a browser. So are the informations stored and updated in a
textfile or something like that? Can anybody help me with this?

No, libvirt reads it from the qemu QMP command query-blockstats. Beyond

[API reference] Are there XML-handling API to retrieve info directly from xml configure file

Unable to collect VM metrics for ESX using libvirt
Hi,
I am trying to connect to a server running esx and collect system metrics
like cpu usage, network and disk iops. I am able to establish the

I am using the python interface and if I do ,

Monitoring and statistics through libvirt
Hi folks,
is it possible to monitor and gather statistics in realtime (CPU,
memory, HDD, network, ... - something like dstat) of guest systems
with libvirt through console from host system (KVM based)? If yes, do
those guests need to be created through libvirt? Thanks for your help
and time.

[PATCH Fedora libguestfs] Don't depend on libvirt-daemon-kvm monolith.
libguestfs usually needs qemu. However it only requires an emulator
for the same architecture, not for all architectures.
libvirt-daemon-kvm pulls in qemu which pulls in emulators for all
architectures, as well as a bunch of other stuff we don't need at all
like network interface support and nwfilter.
There are no Fedora TCG-only arches, so drop the conditional section.
I also made support
