2 nagios with same information

Hi people,
i would like to know if it’s possible to have 2 nagios on different servers.

My company works on 2 countries. Each one has many servers… So i would like to put a computer with nagios in each country to monitor their own servers, but also the servers of the other country.

Is there a way to nagios communicate with another nagios?

Thanks a lot
