    FAQ-COM250 : DIFFERENT RESULTS THAN OTHER ANALYZER
    PROBLEM:
    -I also use webalizer (or another log analyzer) and it doesn't report the same results than AWStats. Why ?
    +I also use Webalizer, Analog (or another log analyzer) and it doesn't report the same results than AWStats. Why ?
    SOLUTION:
    If you compare AWStats results with an other log file analyzer, you will found some differences, sometimes very important. In fact, all analyzer (even AWStats) make "over reporting" because of the problem of proxy-servers and robots. However AWStats is one the most accurate and its "over reporting" is very low where all other analyzers, even the most famous, have a very high error rate (10% to 2x more than reality).
    This is the most important reasons why you will find differences:
    -- Some dynamic pages generated by CGI programs are not counted by some analyzer (ie Webalizer) like -a "Page" (but only like a "Hit") if CGI prog has not a .cgi extension, so they are not included -correctly in their statistics. AWStats does not make this error and all CGI pages are pages.
    -- AWStats is the alone analyzer (that i know for the moment) able to detect robots visits. -All other analyzers think it's a human visitor. This error make them to report more visits and visitors -than reality. This does not happen with AWStats. When it tells "1 visitor", it means "1 human visitor". -All robots hits are reported in the "Robots/Spiders visitors" chart.
    -- A lot of analyzer (ie webalizer) use the "Hits" to count visitors. This is not a good way of working : +
  • Some dynamic pages generated by CGI programs are not counted by some analyzer (ie Webalizer) like +a "Page" (but only like a "Hit") if CGI prog does not end with a defined extension (.cgi, ...), so they are not included +correctly in their statistics. AWStats use on oposite policy, assuming a file is a page except if +type is in a list (See NotPageList parameter). Error rate +with a such policy is lower.
    +
  • AWStats is able to detect robots visits. Most analyzers think robots visits are human visitors. +This error make them to report more visits and visitors than reality. +When AWStats reports a "1 visitor", it means "1 human visitor" (even if it's not posible to detect +all robots, most of them are detected). "Robots visitors" are reported separately in the "Robots/Spiders visitors" chart.
    +
  • Some log analyzers use the "Hits" to count visitors. This is a very bad way of working : Some visitors use a lot of proxy servers to surf (ie: AOL users), this means it's possible that several hosts (with several IP addresses) are used to reach your site for only one visitor (ie: one proxy server download the page and 2 other servers download all images). Because of this, if stats of unique visitors are made on "hits", -3 users are reported but it's wrong. So AWStats, like HitBox, considers only HTML "Pages" to count unique visitors. +3 users are reported but it's wrong. So AWStats considers only HTML "Pages" to count unique visitors. This decrease the error, not completely, because it's always possible that a proxy server download one HTML frame and another one download another frame, but this make the over-reporting of unique visitors less important.
    -There is also differences in log analyzers databases and algorithms that make details of results less or more accurate:
    -- AWStats has a larger browser, os and search engine database, so reports concerning this are more accurate.
    -- AWStats has url syntax rules to find keywords or keyphrases used to find your site, but AWStats has also +
  • Another important reason to have difference is that an error log files is not always completely sorted +but only "nearly" sorted because of cache and writing log engines used by server. Nearly all log +analyzers (commercial and not) assumes that log file is "exactly" sorted by hit date to calculate +visits, entry and exit pages. AWstats has an advanced parsing algorithm that is able to count visits, +entry and exit pages even if log file is only "nearly" sorted.
    +
  • To differenciate new visits of a same visitor, log analyers uses a visit time-out. If value differs, +then results differ (on visit count and entry and exit pages). +A such time-out is a fixed value (For example 60 minutes) meaning if a visitor make a hit +59 minutes after downloading the previous page, it's the same visits, if he make it 61 minutes after, it's a new visit. +Of course, there is no realy difference between 59 and 61, but couting visits without +time-out is not possible. And because the most important is to have a time-out (and not +really it's value), AWStats time-out is not an "exact" value but is "around" 60 minutes. +This allows AWStats to have better speed processing time, so you also might experience +little differences, in visit count, between AWStats and another log analyzer even if +their time-out are both defined to same value (because AWStats time-out is not exactly +but nearly value defined).
