I'm looking for a single Web Site Measurement package (not hosted,
preferably) that will enable us to do four things:
1.) Basic Stats - number of visitors, time on site, pages per session,
browser version, etc.
2.) Monitoring - this would be able to tell things like response time, error
conditions, email notifications of static & dynamic thresholds (any page
that takes longer than 20 seconds to get a response to the person), etc.
