Analog 5.2: Analog's reports
This section summarises all of analog's reports, and the main commands which
control them. For details on these commands, see the sections on
Time reports,
Other reports and
Hierarchical reports.
For exact details on what is counted in each report, see the section on
Analog's definitions.
You can get descriptions of each report within the output by using the
DESCRIPTIONS and
DESCFILE commands.
Program started at Thu-24-Sep-1998 13:48.
Analysed requests from Wed-16-Sep-1998 09:52 to Mon-21-Sep-1998
02:04 (4.7 days).
The top two lines of the output tell you when the program was run, and
which dates it includes data from.
(Figures in parentheses refer to the 7 days to 24-Sep-1998 13:48).
Successful requests: 79,646 (48,947)
Average successful requests per day: 17,036 (6,992)
Successful requests for pages: 31,138 (18,689)
Average successful requests for pages per day: 6,660 (2,669)
Failed requests: 9,008 (6,378)
Redirected requests: 344 (235)
Distinct files requested: 8,180 (2,884)
Distinct hosts served: 6,640 (4,991)
Corrupt logfile lines: 2
Data transferred: 976.92 Mbytes (627.06 Mbytes)
Average data transferred per day: 208.96 Mbytes (89.58 Mbytes)
The General Summary contains some overall statistics about the data being
analysed: the most important being the number of requests (the total
number of files downloaded, including graphics); the number of requests for
pages (just counting the various pages on your site); the number of
distinct hosts (the number of different computers requests have come
from); and the amount of data transferred in bytes. For exactly what
the various lines mean, see the section on Analog's
definitions. Bear in mind that one user can generate many requests
by viewing lots of different pages or images, or by viewing the same page many
times.
The figures in parentheses represent the seven days given at the top of this
report: it's the seven days before the TO time if there was a
TO command, or if not the seven days before the program was run.
You can't find out the number of visitors or visits you've had, and don't
believe any program which tells you that you can. See the section on
How the web works for a discussion of
this.
You can turn this report on or off with the
GENERAL command.
You can control which lines are included using the
GENSUMLINES command.
You can include
or exclude the figures for the last seven days with the
LASTSEVEN command.
You may get slightly different lines to those above, depending on exactly
what's in your logfile.
Each unit () represents 800 requests for pages, or part thereof.
week beg.: #reqs: pages:
---------: -----: -----:
13/Sep/98: 69614: 25277:
20/Sep/98: 10032: 5861:
Busiest week: week beginning 13/Sep/98 (26,654 requests for pages).
These reports tell you how many requests there were in each time
period. They also tell you which was the busiest time period.
You can control whether each report is included or not with the appropriate
ON or OFF command.
You can control which columns are listed by the
COLS commands. You can control
which measurement to use for the bar charts and the "busiest" line
by the GRAPH commands. You can
determine how many rows are displayed with the
ROWS commands. You can display the
lines backwards or forwards in time by the
BACK commands. You can change the
graphic used for the bar charts with the
BARSTYLE command.
Each unit () represents 150 requests for pages, or part thereof.

[etc.]
These reports tell you the total number of requests in each day or hour of the
week, or in each period of the day, summed over all the weeks or days in the
report. (It's not the average, nor is it the figures for just the last week or
last day).
You can control whether each report is included or not with the appropriate
ON or OFF command.
You can control which columns are listed by the
COLS commands. You can control
which measurement to use for the bar charts by the
GRAPH commands. You can change the
graphic used for the bar charts with the
BARSTYLE command.

The rest of the reports are all quite similar. Here is a list of them. If
you're unfamiliar with some of the terms, see the section on
Analog's definitions.
- The Host Report lists all computers which downloaded files from you.
- The Domain Report lists which countries those computers came
from. (If you only get "unresolved numerical addresses", see the
FAQ.)
- The Organisation Report attempts to
list the organisations (companies, institutions, ISPs etc.) which
the computer was registered under.
- The Host Redirection Report and Host Failure Report list all computers
which encountered redirections or errors.
- The Request Report (the example above) lists which files were
downloaded.
- The Directory Report lists which directories those files came from.
- The File Type Report lists the file types (actually, extensions) of
those files.
- The File Size Report breaks them down by size.
- The Processing Time Report shows the time taken to serve each file.
- The Redirection Report lists the filenames which resulted in redirections:
mainly directories without the final slash, and
"click-thru"'s.
- The Failure Report lists the filenames which caused errors.
- The Referrer Report lists which pages linked to your files (and
also pages which included your images).
- The Referring Site Report lists the servers those referrers were on.
- The Search Query Report and the Search Word Report list which search
terms people used to find your site (provided you've used the
appropriate SEARCHENGINE
commands).
- The Internal Search Query Report and Internal Search Word Report list the
search terms people used on scripts within your site (provided
you've used the appropriate
INTSEARCHENGINE commands).
- The Redirected Referrer Report lists the referrers which led to
redirections.
- The Failed Referrer Report is essentially a broken link report.
- The Browser Report lists the detailed versions of browsers used,
and the Browser Summary collects them by vendor. You should be aware that
browsers can lie about what sort of browser they are.
- The Operating System Report lists the operating systems of the
visitors whose browser types you know (as far as possible: it's not always
possible to distinguish accurately between different Windows versions, for
example, because the same browser can run on more than one Windows
version).
Which browsers count as robots is controlled by the
ROBOTINCLUDE and
ROBOTEXCLUDE commands.
- The Virtual Host Report lists the activity of your various virtual
domains.
- The Virtual Host Redirection Report and Virtual Host Failure Report give
the number of redirections and errors on each of those domains.
- The User Report lists your visitors if your server requires
authentication, or perhaps the visitors' cookies.
- The User Redirection Report and User Failure Report list the users who
encountered redirections or errors.
- The Status Code Report lists the number of each
HTTP status code that you had.
Usually you can only get some of these reports, depending on what information
is recorded in your logfile.
There are lots of commands which control these reports.
As usual, you can control whether each report is included or not with the
appropriate ON or OFF
command.
You can control which columns are listed with the
COLS commands.
You can change how the reports are sorted with the
SORTBY commands.
You can control how many items are listed with the
FLOOR commands.
You can control whether and how the pie charts are plotted with the
CHART commands.
You can list the time period covered by each report with the
REPORTSPAN command.
You can include or
exclude individual items with the output
INCLUDE and EXCLUDE commands.
You can change the names of items in the reports with the
output alias commands.
Which files are linked to in the reports is controlled by the
LINKINCLUDE and
LINKEXCLUDE commands. The links are also affected by the
BASEURL command.
The "not listed" line at the bottom counts those items which
didn't get enough traffic to get above the FLOOR for the report.
(It doesn't include items which you've explicitly
excluded.)
Most of these reports have a hierarchical structure, like this example for
the Domain Report:
Listing the first 5 domains by the number of requests, sorted by
the number of requests.
no.: #reqs: %bytes: domain
---: -----: ------: ------
1: 13243: 16.23%: .com (Commercial)
: 1262: 1.26%: aol.com
2: 11783: 25.64%: .jp (Japan)
: 9592: 22.19%: ad.jp
: 1043: 1.97%: co.jp
3: 10073: 11.62%: .net (Network)
: 1926: 1.71%: uu.net
4: 9657: 13.31%: [unresolved numerical addresses]
5: 7388: 8.04%: .uk (United Kingdom)
: 5792: 5.74%: ac.uk
: 1510: 1.99%: co.uk
: 18502: 25.16%: [not listed: 82 domains]
Notice that the lower levels are always listed with their parents, so they
break up the sort order. Also, they don't count towards the total number of
items listed, so there are only 5 domains listed in the example above, as you
can see in the first column. (The N
column is particularly useful in hierarchical reports for this reason.)
You can control which items are listed on the lower levels by the
SUB family of commands.
There are also separate
sub-SORTBY and
sub-FLOOR commands for the
lower levels. (These commands are called
ARGSSORTBY and
ARGSFLOOR for some reports,
such as the Request Report.) You can plot the lower levels instead of the
top-level items on the pie charts using the
CHARTEXPAND commands.
This analysis was produced by analog 5.2.
Running time: 8 seconds.
At the end of the output you can see which version of analog produced the
report, and how long it took.
