Why are certain files missing from the Urchin reports?
The answer depends on the tracking method that you are using. If you are using the UTM tracking method make sure all of your pages are tagged with the __utm.js tracking code. Pages that are not tagged will not appear in your reports. Also, Urchin only tracks pages that return a 200 or 304 status.
If you are using an IP based tracking method, make sure that you are not hitting Urchin’s internal database table limit. By default, tables in the Urchin database have a limit of 60,000 records. If you hit this limit then all subsequent page hits will be bundled in a record named “(other)”. If you are hitting the db table limit you can increase the table limit beyond 60,000 records.
