To view statistics for a specific month, click the month from the month column of the "Summary by month" table.
The various statistics that Web Stats generates are described below:
Hits
Any request made to the server which is logged is considered a "hit". The requests can be for any resource: HTML pages, graphic images, audio files, cgi scripts, etc. Each valid line in the server log is counted as a hit. This number represents the total number of requests that were made to the server during the specified report period.
Hits by response code
After a client makes a request to the server, the server returns a response code (status code). The Response code shows the result of the request. "Hits by response code" represents the total number of requests that received the same specified status code. Some common response codes are:
200 OK
302 Found
304 Not Modified
400 Bad Request
401 Unauthorized
403 Forbidden
404 Not found
500 Server error
Files
Some requests made to the server require that the server responds to the requesting client. This type of request is considered a "file" and the file total is incremented. The relationship between "hits" and "files" may be thought of as "incoming requests" and "outgoing responses".
Pages
Any HTML document, or process that generates an HTML document, is considered a page. This does not include graphic images, audio clips, etc. This number represents only the number of "pages" requested. What actually constitutes a "page" is determined by file extension.
Agents
A user agent is a web browser. The User Agent statistic details the type and version of the browsers used to view the domain.
Sites
Each request made to the server comes from a unique site, which can be referenced by a name or an IP address. The site's number shows how many unique IP addresses made requests to the server during the reporting period.
Visits
Whenever a request is made to the server from a given IP address, the amount of time since a previous request by the address is calculated. If the time difference is greater than a pre-configured "visit timeout" value (or has never made a request before), it is considered a "new visit". This total is incremented both for the site, and the IP address. The time-out value is 30 minutes.
KBytes
The KBytes (kilobytes) value shows the amount of data, in KB that was sent out by the server during the specified reporting period. This value is generated directly from the log file, so it is up to the web server to produce accurate numbers in the logs. In general, this should be a fairly accurate representation of the amount of outgoing traffic.
