If a log file contains IP address of user's host, the program determines user's country using the IP to country geolocation database based on Whois records. If the log file contains already resolved IP address (domain name) the program determines country by the top-level domain. In most cases log files contain unresolved IP addresses. Determining country by IP using the geolocation database is more accurate than using domain names.

The program requires additional databases which can be downloaded from the program's website. These databases are based on Whois records and allow the program to determine users' state, city and organization by IP address.

The program determines number of visitors by the IP addresses. If a request from an IP address came after some time (timeout) since the last request from this IP, it is considered to belong to a different visitor. The timeout is set to 30 minutes by default but you can change this value in Options > Analysis > General. Requests from spiders aren't used to determine visitors unless the Count spiders as visitors option is enabled.

Use the Virtual domain filter.

Create an exclude Spider filter and use "*" wildcard (without quotes) as a spider name to exclude all the recognized spiders. [ View demo]

Create an include Requested file filter with wildcard like "/dir/*" (without quotes). [ View demo]

If you wish to filter out requests for specific profile only you can use an exclude Host filter. You can also exclude such requests from all profiles using the host ignore list in Options > Analysis > Ignore Lists.
