Examples of self-contained calculations which can be performed within a stack probe:
App-to-wire
Gap detection
Examples of non self-contained calculations which are more suitable to perform in VMX-Analysis:
North/south latency (e.g. gateway latency) where it is a different protocol either side of the gateway.
Even though the P3 process can process data from multiple stack probes, it still has limited capability to track state or preserve information from message to message. This type of analysis is better performed by passing the individual Agent Events to VMX-Analysis.
