Extension:Access Log

The Access Log extension adds a special page to MediaWiki. This special page, which is only accessible by certain privileged users, shows who read or edited a page, and when. It provides options to filter the list by user, action, and/or namespace, and limit the number of days to show. It also provides an option to purge old log entries.

Usage
The AccessLog extension is a MediaWiki Special Page. Only members of the 'sysop' group, and if set, members of the group defined in the $wgAccessControlPanelAllowedGroup variable, can access this special page. There are two ways to invoke this special page and view the access log:


 * 1) Directly navigate to the page 'Special:AccessLog'.
 * 2) Enter the 'Special Pages' page and click on the AccessLog special page.

The following shows the access log page, with the filter box:

 * MySQL database servers are required; PostgreSQL and SQLite are not supported.
 * MediaWiki database administrator access (or other database role that has privileges for creating SQL functions).

Step by Step Instruction
Step 1: Download the archive file from the link above.

Step 2: Extract the downloaded archive to the extensions directory of your MediaWiki installation. For example (replace with the actual path to your MediaWiki installation):

Step 3: Add the following line to the bottom of LocalSettings.php (before the trailing ?>, if it is present):

Step 4 (optional): Disable client side caching to make sure every page view request hits the server and thus gets logged. Set $wgCachePages to false in LocalSettings.php:

Step 5: Update the MediaWiki database by executing the update.php maintenance script.

Step 6: As an administrator (sysop) user, visit the page 'Special:AccessLog' in your MediaWiki installation. If everything went well you should see the AccessLog special page.

Step 7 (optional): By default, actions from anonymous users are ignored. To log actions from anonymous users, add the following line after the require_once statement of step 3:

Step 8 (optional): If you are using the Access Control Panel extension, the members of $wgAccessControlPanelAllowedGroup can also access the access log page. If you are not using that extension, but want to grant access privilege to non-sysop users, create a new user group. Add the following lines to LocalSettings.php. After that, add user(s) who are going to read the access log into 'ControlGroup' (or whatever name you chose for this group). For detailed steps, please visit Help:Assigning permissions.

Upgrading from older versions
Step 1: Download the newer version archive from the link above.

Step 2: Extract the downloaded archive to the extensions directory of your MediaWiki installation and replace the old version files. For example (replace with the actual path to your MediaWiki installation):

Step 3: Update the MediaWiki database by executing the update.php maintenance script.

Step 4 (optional): In the previous step, newly introduced columns are filled with NULL values for old entries. Because of that, old entries will not be displayed when the log filter is used. To apply filters for old entries, update the old entries (fill in the newly introduced columns) by executing the updateLogRecord.php maintenance script.
