The use of the Syslog module instead of the Database Logging module on the Acquia Platform increases the performance in several ways,

• It stops logs from being written into the database, which affects performance and fills your database volume
• Acquia support can better assist with the analysis of performance, and diagnosis of your any issue your website might be displaying.
• You can use a log forwarding service https://docs.acquia.com/acquia-cloud/monitor/logs/forwarding/.

To enable the Syslog module use the following Drush command `drush en syslog`, or via your Drupal UI navigate to example.com/admin/modules and enable the module.

Once you have enabled the module and navigate /admin/config/development/logging you will need to update the Syslog configuration. In order that there is an appropriate level of logging verbosity for a production environment, it is good to update the configuration so that additional details will then be written into the drupal-watchdog.log.

We recommend making the following changes :

• Set the Syslog identity value to the site name (so a meaningful value is written to the log)
• Set the Syslog facility to: `LOG_LOCAL0`
• Set the Syslog format to: `!base_url|!timestamp|!type|!ip|!request_uri|!referer|!uid|!link|!message`
