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 gauge 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 transferred 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 accessible to the
remote user, or results in an error (i.e.: 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 Israel, 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.
