Meaning
|
|
Hits
|
A hit is any response from
the server on behalf of a request sent from a browser. For example, an
HTML page has two images embedded. The server generates three hits if
this page is requested: one hit for the HTML page itself and two hits
for the images.
|
|
Files
|
If the user requests a document
and the server successfully sends back a file for this request, this
is counted as a Code 200 (OK) response. Any such response is
counted for as a file. Again, "file" here means any kind of
a file.
|
|
Code
304
|
A Code 304 (Not Modified)
response is generated by the server if a document hasn't been updated
since the last time it was requested by the user and therefore there
was no need to actually send the files for this document. This happens
if the browser (or a caching proxy server between the browser and your
web server) still has an up-to-date copy of the page in it's local
storage (cache) and therefore can display the page without requesting
the actual content.

|
Page
views
|
Page views are all files which
either have a text file suffix (.html,
.text) or which are
directory index files. This number allows to estimate the number of
"real" documents transmitted by your server. If defined
correctly, the analyzer rates text files (documents) as page views.
Those page views do not include images, CGI scripts, Java applets or
any other HTML objects except files ending with one of the
pre-defined page view suffixes, such as .html
or .txt.

Other
responses
|
-
Code 302
(Redirected) response if a page has moved
-
Code 401
(Unauthorized Request) response if access to the document is
denied
-
Code 404 (Not Found) response if the requested page
does not exist on this server.

|
KBytes
transferred
|
This is the amount of data sent
during the whole summary period as reported by the server. Note that
some servers log the size of a document instead of the actual number
of bytes transferred.
|
|
KBytes
requested
|
This is the amount of data
requested during the whole summary period. http-analyze
computes this number by summing up the values of KBytes transferred
and KBytes saved by cache (see below).
|
|
KBytes
saved by cache
|
The amount of data saved by
various caching mechanisms in proxy servers or browsers.
This value is computed by multiplying the number of Code 304 (Not
Modified) requests per file with the size of the corresponding
file. The values for KBytes
saved by cache and KBytes requested are just approximations
of the real values.
|
|
Unique
URLs
|
Unique URLs
are the number of all different, valid URLs requested in a given
summary period. This shows you the number of all different files
requested at least once in the corresponding summary period.
|
|
Unique
sites
|
This is the sum of all unique
hosts accessing the server during a given time-window. If a host
(visitor) accesses your server more than once, it gets counted
only once during the whole month. Only the sum of the unique hosts per
month is listed in the statistics report.
|
|
Sessions
|
Similar to unique sites,
this is the number of unique hosts (visitors) accessing the server during a given
time-window. This time-window is one day by default for backward
compatibility.
