No, the URL sent in the Notification email for that Event would not have a link back to NFA itself.
Though the URL in the Notification email from CAPC will contain a URL leading back to the CAPC system, for the element involved in the Event in the email.
Once that URL is launched and the user is logged into CAPC, NFA data can be observed in the appropriate CAPC Dashboards and Views, assuming NFA is a configured Data Source within CAPC.
If that is the case with an NFA Data Source configured in CAPC, a direct Netflow UI/View could be launched out of CAPC assuming the user logging into CAPC has permissions to do so for the NFA Data Source.
