1. A network system comprising:
memory configured to store data indicative of a predefined probe packet budget; and
processing circuitry communicatively coupled to the memory and configured to:
receive a message comprising:
a ranking of most-used applications associated with the network system; and
for each of the most-used applications:
a ranking of most-used servers for a respective most-used application; and
a respective network address and respective probe protocol for each of a plurality of network devices associated with the most-used servers;
determine a subset of the plurality of network devices, based on the ranking of the most-used applications, the ranking of the most-used servers, and the predefined probe packet budget; and
send an out-of-band probe packet, the out-of-band probe packet not carrying live traffic, to each of the subset of the plurality of network devices, using the respective network address and the respective probe protocol.
