36 <a name="Unique Visitor"><b>Unique Visitor</b></a>:<br>
37 A unique visitor is a host that has made at least 1 hit
38 on 1 page of your web site during the current period shown by the report.
39 If this host make several visits during this period, it is counted only once.<br>
40 The period shown by AWStats reports is by default the current month.<br>
41 However if you use AWStats as a CGI you can click on the "year" link to have a report for all the year.
42 In a such report, period is full year, so Unique Visitors are number of hosts that have made at least 1 hit
43 rizwank 1.1 on 1 page of your web site during those year.<br>
44 <hr>
45
46 <a name="Visits"><b>Visits</b></a>:<br>
47 Number of visits made by all visitors.<br>
48 Think "session" here, say a unique IP accesses a page, and then requests three others without an hour
49 between any of the requests, all of the "pages" are included in the visit, therefore you should expect
50 multiple pages per visit and multiple visits per unique visitor (assuming that some of the unique IPs are
51 logged with more than an hour between requests)<br>
52 <hr>
53
54 <a name="Pages"><b>Pages</b></a>:<br>
55 The number of "pages" logged. Only files that don't match an entry in the NotPageList config
56 parameter (and match an entry of OnlyFiles config parameter if used) are counted as "Pages".
57 Usually pages are reserved for HTML files or CGI files, not images nor other files requested as a result
58 of loading a "Page" (like js,css... files).<br>
59 <hr>
60
61 <a name="Hits"><b>Hits</b></a>:<br>
62 Any files requested from the server (including files that are "Pages") except those that match
63 the SkipFiles config parameter.<br>

72 First page viewed by a visitor during its visit.<br>
73 Note: When a visit started at end of month to end at beginning of next month,
74 you might have an Entry page for the month report and no Exit pages.<br>
75 That's why Entry pages can be different than Exit pages.<br>
76 <hr>
77
78 <a name="Exit Page"><b>Exit Page</b></a>:<br>
79 Last page viewed by a visitor during its visit.<br>
80 Note: When a visit started at end of month to end at beginning of next month,
81 you might have an Entry page for the month report and no Exit pages.<br>
82 That's why Entry pages can be different than Exit pages.<br>
83 <hr>
84
85 rizwank 1.1 <a name="Session Duration"><b>Session Duration</b></a>:<br>
86 The time a visitor spent on your site for each visit.<br>
87 Some Visits durations are 'unknown' because they can't always be calculated. This is the major reason for this:<br>
88 - Visit was not finished when 'update' occured.<br>
89 - Visit started the last hour (after 23:00) of the last day of a month (A technical reason prevents AWStats from
90 calculating duration of such sessions).<br>
91 <hr>
92
93 <a name="Grabber"><b>Grabber</b></a>:<br>
94 A browser that is used primarily for copying locally an entire site. These include
95 for example "teleport", "webcapture", "webcopier"...<br>
96 <hr>
97
98 <a name="AddToFavourites"><b>Add To Favourites</b></a>:<br>
99 This value, available in the "miscellanous chart", reports an estimated value of the number
100 of times a visitor has added your web site into its favourite bookmarks.<br>
101 The technical rules for that is the following formula:<br>
102 <i>Number of Add to Favourites = round((x+y) / r)</i><br>
103 where<br>
104 x = Number of hits made by IE browsers for "/anydir/favicon.ico", with a referer field not defined, and with no 404 error code<br>
105 y = Number of hits made by IE browsers for "/favicon.ico", with a referer field not defined, with or without 404 error code<br>
106 rizwank 1.1 r = Ratio of hits made by IE browsers compared to hits made by all browsers (r <= 1)<br>
107 <br>
108 As you can see in formula, only IE is used to count reliable "add", the "Add to favourites"
109 for other browsers are estimated using ratio of other browsers usage compared to ratio of
110 IE usage. The reason is that only IE do a hit on favicon.ico ONLY when a user add the page
111 to its favourites. The other browsers make hits on this file also for other reasons so
112 we can't count one "hit" as one "add" since it might be a hit for another reason.<br>
113 AWStats differentiate also hits with error and not to avoid counting multiple hits
114 made recursively in upper path when favicon.ico file is not found in deeper directory
115 of path.<br>

118
119 <a name="HTTP"><b>HTTP Status Codes</b><a>:<br>
120 HTTP status codes are returned by web servers to indicate the status of a request.
121 Codes <b>200</b> and <b>304</b> are used to tell the browser the page can be viewed.
122 All other codes generates hits and traffic 'not seen' by the visitor. For example a return
123 code 301 or 302 will tell the browser to ask another page. The browser will do another hit
124 and should finaly receive the page with a return code <b>200</b> and <b>304</b>.
125 All codes that are 'unseen' traffic are isolated by AWStats in the HTTP Status report chart,
126 enabled by the directives <a href="awstats_config.html#Show">ShowHTTPErrorsStats</a>.
127 rizwank 1.1 in config file. You can also change value for 'not error' hits (set by default to <b>200</b> and <b>304</b>
128 with the <a href="awstats_config.html#ValidHTTPcodes">ValidHTTPcodes</a> directive.
129 The following table outlines all status codes defined for the HTTP/1.1 draft specification
130 outlined in <a href="http://www.w3.org/Protocols/rfc2068/rfc2068">IETF rfc 2068</a>.<br>
131 They are 3-digit codes where the first digit of this code identifies the class of the status
132 code and the remaining 2 digits correspond to the specific condition within the response class.
133 They are classified in 5 categories:<br>
134 <ul>

413
414 SMTP status codes are returned by mail servers to indicate the status of a sending/receiving mail.
415 The status code depends on mail server and preprocessor used to analyze log file.<br>
416 All codes that are failure codes are isolated by AWStats in the SMTP Status report chart,
417 enabled by the directives <a href="awstats_config.html#Show">ShowSMTPErrorsStats</a> in AWStats
418 config file. You can decide which codes are successfull mail transfer that should not appear
419 in this chart with the <a href="awstats_config.html#ValidSMTPCodes">ValidSMTPCodes</a> directive.<br>
420 Here are values reported for most mail servers (This should also be values when mail log file
421 rizwank 1.1 is preprocessing with maillogconvert.pl).<br>
422 SMTP Errors are classified in 3 categories:<br>
423 <ul>
424 <li><font face="arial"><font size=-1><a href="#SMTP23">2xx/3xx - successful</a></font></font></li>
425 <li><font face="arial"><font size=-1><a href="#SMTP4">4xx - failure, asking sender to try later</a></font></font></li>
