Well, I used to monitor a kvm vm by a script reading info from files such as /proc/stat, /proc/loadavg, /proc/meminfo, /proc/diskstats, /proc/net/dev. Through those files under /proc, I can get the whole statistic info of the vm including cpu/memory/disk/net. If I want to do the same work in lxc supported by libvirt, How can I make it? BTW, I know virt-top can do such things. But what I want is a programming way such as libvirt interface.
