A fairly frequent request I am now getting goes along these lines:
I need to setup some monitoring between:
Source: 1.2.3.4
Destination: 6.7.8.9
For now, forget the tech behind these devices because they could be anything from physical servers to network kit to virtual devices, then what is the best approach to monitoring traffic between them?
If it helps - we have NPM and NetFlow which can be utilised.
