Each physical or virtual server requires one FusionReactor license – all of the instances which are installed on that server are covered by the one FusionReactor license. So, if you have (say) 6 physical boxes, then you need 6 licenses. Note, that on a single box you may have multiple instances (JRun, Tomcat, JBoss, ColdFusion) installed on it, but you still only need 1 license for that (virtual or physical) server. Virtual Machines (VM’s) are also classed as separate physical servers and therefore require a license.
If you would like to use the FusionReactor Enterprise Dashboard functionality to be able to monitor all the servers from a single window, then you will need to take the FusionReactor Enterprise Edition on all the servers you wish to monitor. Therefore if you would like to monitor 3 servers with the FusionReactor Enterprise Dashboard you will need 3 x FusionReactor Enterprise licenses.
