1.   Error: No events qualified for processing.
This usually indicates that the log data is not being interpreted correctly.  Use the "Test Interpretation" tool (on the Tools menu) to see how the log data is interpreted.  Make sure there are no warnings in the "Warnings" column.  If there are, or if it appears that the log data is not being correctly interpreted, go to the Settings tab, set the Log Format to "(custom)", and manually configure the Custom Log Format table.

2.   Error: Out of Memory.
If Serlog is reporting an "Out of Memory" error, we recommend taking the following actions:

  • Make sure the "Domain" field on the Settings folder is specified.
  • Check the "Consolidate Referrers" box on the Settings folder.
  • Restart Serlog between separate Analyze operations.
  • If one log is much bigger than all others due to some sort of attack, delete all lines from the log containing the IP address of the attacker.
  • Reduce the number of logs being analyzed.

3.   How should IIS be configured?
By default, IIS 6 does not log the "Referrer" or bandwidth data.  This prevents the Bandwidth, Misreferrals, Referrals, Search Engines, and Search Keywords reports from working.  Follow this procedure to force IIS to log this information:

  • Go to Control Panel > Administrative Tools > Internet Information Services (IIS) Manager > Web Sites > [your website] > Properties.
  • On the Web Site tab, set Active Log Format to "W3C Extended Log File Format".
  • Click the "Properties" button.  Switch to the "Advanced" tab.
  • Make sure the following options are checked:
    Date ( date )
    Time ( time )
    Client IP Address ( c-ip )
    Method ( cs-method )
    URI Stem ( cs-uri-stem )
    Protocol Status ( sc-status )
    Bytes Sent ( sc-bytes )
    Bytes Received ( cs-bytes )
    Time Taken ( time-taken )
    User Agent ( cs(User-Agent) )
    Referer ( cs(Referer) )
  • Click OK twice and exit the IIS manager.

4.  Our style sheet is listed as a popular entry page.
A style sheet can appear to be a popular entry page if it is referred to by any file type that requires server-side processing, such as PHP, CGI, or ASP.  What happens is that the processed file appears later in the server log than it should, due to the processing overhead.  This makes it appear like the style sheet was requested first, even though it was not.  The only solution to this problem is to exclude the style sheet from the report.  We recommend checking the "Pages Only" box.

5.  What advantages does Serlog have over Google Analytics?
Serlog can be a valuable source of information that Google Analytics cannot provide.  Specifically:

  • Google Analytics can only track hits on HTML files.
  • Google Analytics does not offer the following reports:  Bandwidth, Directories, File Types, Misreferrals, Search Engines, Spiders.
  • Google Analytics can only track conversions that originate from Google Adwords.
  • The Search Keyword report in Google Analytics only includes keywords that originate from Google.
  • Google Analytics cannot track HTTP requests that produce an error.
  • Google Analytics cannot graph data for a subset of files.  For example, we often use Serlog to produce a graph of the number of downloads of Gammadyne Mailer.
  • Google Analytics only keeps data for 2 years.
  • Google Analytics requires tracking code to be inserted into every web page.
