Hi,

I have a requirement to scan Apache logs and discover ``exceptions''. Exceptions can be of two types:

  1. A single IP generating a large amount of traffic within a given time frame (for definable values of ``large'' and ``time frame'').
  2. A single IP hitting a wide set of URLs on the server (indicates a crawler), again for definable values of ``wide''.

I'm a complete newbie to R (and to statistics), so the questions are:

Data massaging, tuning, etc. are not an issue. We'd be dealing with a few hundred thousand or a million records a day.

Regards,
