I have a server running Ubuntu desktop. It is configured as a KVM virtual host. I have three virtual servers running Ubuntu server. I am wanting to use Munin to alert me if the hard drives fill past a certain point and want to see what my monthly bandwidth is. If I set up munin on the host, can I monitor network usage for that machine only AND for all four machines (host and three virtual servers)? I know I have a virtual bridge set up so I am guessing I can configure munin node to monitor the bridge to get all machines, but can I also monitor just the host without the virtual servers? I think the host uses a virtual Ethernet adapter that I am thinking I can monitor.
