Record, monitor and capture User activity on my router (my lan)

[Silvakair]

hi everyone
as part of my University project I want to record, monitor and capture user activity. I will be using TP-Link router model WRD 3600.
the aim is to profile the user's activity "on the router", so at first instance I will be recording things like DNS queries, and making a database on the router, periodically updating a server, so devices will be clients, and the router just needs internet access for updating a remote server
your help would be much appreciated
best regards
