User-Agent Log Watch (ULW) processes custom Apache logs and reports hits based on combinations of URL, user agent, and remote IP address. It maintains a list of known IPs, so they aren't reported twice. The list of URL/UA/IP is stored in a configuration file, and its entries can be regexp-understood by gawk. It can be cronned or it can call mail/sendmail. The custom log is reset each time ULW is invoked and processed logs are gzipped and stored in a different location.
