Quick Help
Main Headings
Hits represent the total number of requests made to the server during the given
time period (month, day, hour etc..).
Files represent 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 cache.
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 viewed already).
Sites is 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.
Visits occur 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 visits.
Pages are 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 KByte (KB) is 1024 bytes (1 Kilobyte).
Used to show the amount of data that was transfered between
the server and the remote machine, based on the data
found in the server log.
Common Definitions
A Site is a remote machine that makes requests to your server, and is based
on the remote machines IP Address/Hostname.
URL - Uniform Resource Locator. 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...).
Referrers are 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 page.
Search
Strings are obtained from examining the referrer string
and looking for known 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.
Note: Only available if that information is contained in the
server logs.
User
Agents are a fancy name 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
listing.
Note: Only available if that information is contained in the
server logs.
Entry/Exit pages 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.
Countries 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.
Response
Codes 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.
