Is the /proc dir in lxc container just showing the same thing as the lxc host? If I want to monitor the realtime resource usage inside the lxc container, What should I do?
At this time, the only files in /proc that are virtualized are the /proc/$PID/* files for each process, and the /proc/meminfo global file. All the other files reflect global host state.
Are there particular files in /proc/NNNN that you want to see virtualized in the future ?
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. ------------------ Best regards! GuanQiang 2013-07-24
