To retrieve node cpu statistics on Linux system, the linuxNodeGetCPUstats function simply uses STRPREFIX() to match the cpuid with the one read from /proc/stat. However, as the file is read line by line it may happen, that some CPUs share the same prefix. So if user requested stats for the first CPU, which is offline, then there's no cpu1 in the stats file so the one that we match is cpu10. Which is obviously wrong. Fortunately, the IDs are terminated by a space, so we can utilize that. Signed-off-by: Bing Bu Cao <mars@linux.vnet.ibm.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
