I need to switch from database logging to syslog I'm running a drupal 6 website and I was thinking of speeding it up following these steps:


Completely stop database logging
Enable syslog


How do I configure Drupal to use syslog?
What if I enable just syslog and disable the database log? Do I have to further configure stuff?
This article explains the whole process into details.

The very bottom line is activating the Syslog module (a core module), and configure it on admin/settings/logging/syslog. It should already work out-of-the-box.

To make sure you can find the log file, you can set it in /etc/syslog.conf and /etc/rsyslog.d/50-default.conf.
