Cisco FTD Network discovery

[ciscoworlds]

Hi. Would you clear me on this, taken from the Cisco FTD 6.2.3 config guide (Network Discovery rules section, page 1971)?

"If you want the rule to monitor managed device traffic, application logging is required. If you want the rule
to monitor users, host logging is required. If you want the rule to monitor exported NetFlow records, you
cannot configure it to log users, and logging applications is optional."

What did the author mean by "application logging" or "host logging" in the paragraph?

They are referring to the check boxes in FMC. You have to select Applications first and only then can you also choose Users. Only after choosing Applications and Users can you add Hosts to your network discovery policy.
