user roles

Hi all

I have to design monitoring system, and there will be two main user groups who will use it: network administrators - their main need is to monitor the state of servers, and system monitoring team - their main need is to monitor the services runnig on those servers and some times they don't care about the state of server (if HDD is runnig out of space, load of cpu and so on). I wonder if there is any possibility to separate user roles on Hobbit or any work around for that.

Thanks in advance, Ricardas
