  • Applies to:
  • Plesk 12.0 for Windows


Plesk uses the following components to obtain statistics:

  • "Statistics.exe" utility records monthly statistical data to tables in the "psa" database.
  • "Webalizer/Awstats" utilities store statistics in user-­friendly format accessible via a web browser.

"Statistics.exe" utility



The Statistics utility performs the following tasks:

  • Processes the following log files for the services which produce the majority of network traffic:

    • IIS: %plesk_vhosts%\domain_name\statistics\logs\W3SVC\<number>
    • Mail logs (for MainEnable): %plesk_dir%\Mail Servers\Mail Enable\Logging\
    • FTP logs: %plesk_vhosts%\Servers\<ID>\logs
  • Records monthly statistics data to the psa.* tables. There following tables contain statistics data:
    • Stat -­­ stores overall traffic for every domain calculated for a monthly period.
    • DomainsTraffic -­­ contains domain traffic statistics differentiated by application protocols and directions (in/out).
    • ClientsTraffic -­­ contains customer traffic statistics calculated as the sum of a customer's domains statistics.

How it works:

Since Plesk 11.5 for Microsoft Windows algorithm of statistic calculation has been changed, and web statistic calculated in two steps:

  1. On the first step during Daily Maintenance Script, Plesk parses all statistic data and processes IIS logs in order to prepare it for web-statistic engine (Webalizer or AWstats). As result, during execution Daily Maintenance Script Plesk generates files, which will be used on the second step. For example:

  2. On the second step, 'web_statistics_executor.exe' utility processes all log files, prepared on the first step and web statistic web pages for all websites.

Webalizer/Awstats Utility:

Webalizer/Awstats convert the statistical information into a user-­friendly HTML format and place it to these folders:

  • %plesk_vhosts%\<domain_name>\.plesk\statistics\<domain_name>\webstat
  • %plesk_vhosts%\<domain_name>\.plesk\statistics\<domain_name>\ftpstat


  • AWStats: %plesk_dir%Additional\AWstats\wwwroot\cgi-bin
  • Webalizer %plesk_dir%Additional\webalizer\conf

Note: The conf directories can be found in the Windows registry:


  1. Try to Calculate statistic for one domain according to #116754 article. In case of statistic has been generated successfully, go to next step.
  2. Check that Scheduled Daily Task is present on the server according to the #120967 article.

To check errors reported by Daily Task use the #114065 article.

If after investigations it is required to regenerate statistic from a particular date use #116754 article .
