Nagios monitoring OpenVZ server


Hi all, i want to ask about monitoring OpenVz container with Nagios. Example, I have a host with IP 1.1 using centos 5, and there is four container OpenVZ in that host. Beside that i already have a nagios server with IP 1.2.

What i want to ask is about, how to monitoring all of that container in that host(in IP 1.1)? Can anybody give me any clue for this? :frowning:
