represent the total number of requests made to
the server during the given time period (month, day, hour, etc.).
the total number of hits (requests) that actually resulted in something
being sent back to the user. Not all hits will send data, such as 404-Not
Found requests and requests for pages that are already in the browsers
Tip: By looking at the
difference between hits and files, you can get a rough indication
of repeat visitors, as the greater the difference between the two,
the more people are requesting pages they already have cached (have
the number of unique IP addresses/hostnames that made requests to the
server. Care should be taken when using this metric for anything other
than that. Many users can appear to come from a single site, and they
can also appear to come from many ip addresses so it should be used
simply as a rough guage as to the number of visitors to your server.
when some remote site makes a request for a page on your server
for the first time. As long as the same site keeps making requests within
a given timeout period, they will all be considered part of the same
Visit. If the site makes a request to your server, and the length of
time since the last request is greater than the specified timeout period
(default is 30 minutes), a new Visit is started and counted,
and the sequence repeats. Since only pages will trigger a visit,
remotes sites that link to graphic and other non- page URLs will not
be counted in the visit totals, reducing the number of false
those URLs that would be considered the actual page being requested,
and not all of the individual items that make it up (such as graphics
and audio clips). Some people call this metric page views or
page impressions, and defaults to any URL that has an extension
of htm, html or cgi.
A is 1024 bytes (1 Kilobyte). Used to show the amount of data
transfered between the server and the remote machine based on the data
found in the server log.
is a remote machine that makes requests to your
server and is based on the remote machines IP Address/Hostname.
All requests made to a web server need to request
something. A URL is that something, and represents an
object somewhere on your server, that is accessable to the remote user,
or results in an error (ie: 404 - Not found). URLs can be of any type (HTML, audio, graphics, etc.).
those URLs that lead a user to your site or caused the browser to request
something from your server. The vast majority of requests are made from
your own URLs, since most HTML pages contain links to other objects
such as graphics files. If one of your HTML pages contains links to
10 graphic images, then each request for the HTML page will produce
10 more hits with the referrer specified as the URL of your own HTML

patterns from various search engines. The search engines and the patterns
to look for can be specified by the user within a configuration file.
The default will catch most of the major ones.

fancy names for browsers. Netscape, Opera, Konqueror, etc.. are
all User Agents, and each reports itself in a unique way to your server.
Keep in mind however, that many browsers allow the user to change
it's reported name, so you might see some obvious fake names in the

are those pages that were the first requested
in a visit (Entry), and the last requested (Exit). These pages are calculated
using the Visits logic above. When a visit is first triggered, the requested
page is counted as an Entry page, and whatever the last requested URL
was, is counted as an Exit page.
are determined based on the top level domain of the requesting site.
This is somewhat questionable however, as there is no longer strong
enforcement of domains as there was in the past. A .COM domain may reside
in the US, or somewhere else. An .IL domain may actually be in Isreal,
however it may also be located in the US or elsewhere. The most common
domains seen are .COM (US Commercial), .NET (Network), .ORG (Non-profit
Organization) and .EDU (Educational). A large percentage may also be
shown as Unresolved/Unknown, as a fairly large percentage of
dialup and other customer access points do not resolve to a name and
are left as an IP address.
are defined as part of the HTTP/1.1 protocol (RFC 2068; See Chapter 10). These codes are generated by the web server and indicate the completion status of each request made to it.
