|accesses||An "access" is a single, successful request made by a web
browser. Every successful request for any resource on the web server,
whether for an image or a document or for another type of
information, is regarded as an access. However, this definition
can be changed through the use of the Allowed Documents (allow) and
Ignored Documents (ignore) options, which can be used to include only
accesses to certain types of resources and to explicitly ignore
accesses to others. The definition of a "successful"
request is determined by the Success Codes (successcodes) option.
|agents||An "agent," or user agent, is a web browser or other program used to
access your web server. Most user agents are web browsers such as
Microsoft Internet Explorer and Netscape Navigator, but a significant
number are automated Internet-indexing programs, such as Altavista.
|bytes||A "byte" is a single character of information. In the reports
generated by Wusage, the "bytes transferred" figure refers to
the number of characters of information that were sent to the
browser. This is helpful in determining how much of the
web server's connection to the Internet (how much bandwidth)
is currently in use. It is especially useful to site administrators
who pay for bandwidth by the megabyte or gigabyte on a
|calendar||The Calendar of Reports is a web page which contains links
to all of the reports that have been generated for each individual
epoch, as well as the cumulative summary report. This
is the first page you see upon clicking the View Statistics
button. For more information, see the
Interpreting Wusage Reports section.
|cookies||"Cookies" are pieces of information which can be stored on the
user's browser, at your web server's request. They are useful because
the web browser submits these cookies back to the server on
future visits. This means that individual users can be recognized
again by assigning a unique "cookie" to each visitor. Wusage recognizes
the presence of such cookies in the format produced by the
Apache web server's mod_usertrack module, and also in the format
produced by the Microsoft IIS 4.0 web server. For more information,
see the Server Configuration Tips
|EML||EML (Email Markup Language) is a simple alternative to HTML.
EML is used to create plain-text email messages. EML tags
are similar to HTML tags, but there are far fewer tags and
the table mechanism is much less complex. For more information,
see Email Markup Language (EML)
|epoch||An epoch is an individual time period for which a report
has been generated. Epochs can be days, weeks, months, quarters,
or years, depending on the Daily Reports (daily), Weekly Reports (weekly),
Monthly Reports (monthly), Quarterly Reports (quarterly) and Annual Reports (annual) settings.
The Summary Reports (summary) report can also be thought of as a single
epoch spanning the entire time range over which the program
has been used.
|macro||A "macro" is a string which is recognized as a shorthand for another string.
Wusage uses a report macro language to build its reports. These macros
can be rewritten by the user in order to translate or otherwise
customize the reports. See the Report Macro Language
section for more information.
|query||A Wusage query, or "quick query," is a question which can be answered
by reviewing the data which is preserved by the program for this purpose.
For more information, see the Quick Queries
|trail||A "trail" is a unique path among the documents on the
web server, followed by one or more visitors to the web server.
Every visit to the web server follows a trail.
Commonly followed trails represent useful information about
the preferred routes that your visitors follow. The most commonly
followed trails, above a minimum length determined by the
Top Trails Report: Minimum Steps (trailminimumsteps) option, are reported
as part of the Chart Top Trails (trails) report.
|visit||A "visit" consists of one or more accesses made by the same
visitor, with no more than a certain time interval between
accesses. The maximum time interval is termined by the
Max. Minutes Between Accesses (trailtimeout) option.
When the maximum time interval has elapsed, the visit
is considered to be over, and the next access by that
visitor begins a new visit. However, if it can be determined
that the next access includes "referring URL" information
which points to the website being analyzed, Wusage will
regard it as part of the same visit.
The identity of the visitor is determined by
combining authorized user name, HTTP user-identifying
"cookies", site (IP address), operating system, and
web browser identifying information in order to produce
the most unique "key" possible. Any such fields that are
not actually available are not used. In the simplest
case, where the log file does not contain any other
user-identifying information, only the site (IP address)
of the visitor is used.
