How to change Apache log format for the domains hosted on Plesk?


Answer

1.Log in to the server via SSH

2.Create /usr/local/psa/admin/conf/templates/custom/ custom template folder:

# mkdir -p /usr/local/psa/admin/conf/templates/custom/
3.Copy /usr/local/psa/admin/conf/templates/default/server.php into custom template folder:

# cp -a /usr/local/psa/admin/conf/templates/default/server.php /usr/local/psa/admin/conf/templates/custom/server.php
4.Open /usr/local/psa/admin/conf/templates/custom/server.php file using any text editor.

5.Change log format in custom template in the following section according to Apache documentation:

<IfModule mod_logio.c>
LogFormat "<?php echo $VAR->server->webserver->apache->pipelogEnabled ? '%v@@%p@@' : ''?>%a %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" plesklog
</IfModule>
<IfModule !mod_logio.c>
LogFormat "<?php echo $VAR->server->webserver->apache->pipelogEnabled '%v@@%p@@' ''?>%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" plesklog
</IfModule>

6.Check that the modified template is a valid PHP file:

# php -l /usr/local/psa/admin/conf/templates/custom/server.php
No syntax errors detected in /usr/local/psa/admin/conf/templates/custom/server.php

7.Regenerate server configuration based on the new template:

# plesk sbin httpdmng --reconfigure-server
Warning: Customizing Apache access log format may break webstatistics calculation as webstat tools (Webalizer and Awstats) use Common Log Format (CLF) where each line in a file stored in the Common Log Format has the strictly defined syntax.
