log page views in database where?

[eluser]matt2012[/eluser]
I want to create a simple stats component that logs the page and subpage
of every page view along with some other stuff basically I want to run a
simple database insert of $this->uri->segment(1) etc. where is the best place
to run the code in the construct function of every controller or is this a use of a hook?

or has someone written a plugin or library for this ?
