Java licensing is per node based. A node is nothing but a JVM process configured with java agent. So depending on how many nodes you want to monitor you need to configure java agent to those many nodes. If you want to monitor 100 nodes then you need to have those 100 JVM process configured with java agents.
And coming to .NET license
. Net license usage is at server level and the count never change if on a single server multiple . net applications are getting instrumented. . NET licenses are per machine agent (not app agent) so how many . NET machine agents are reporting could give you count of usage . So current license usage depends on how many of the . net machine agents are reporting at given point of time.
