Enabling and Configuring Drupal's Syslog Module

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, do either of the following:

• Use the following Drush command:

  copy

  drush en syslog

•  In Drupal UI, navigate to example.com/admin/modules and enable the module.

Once you have enabled the module and navigate to /admin/config/development/logging, you must 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 are written in the drupal-watchdog.log.

Acquia recommends the following settings as these match the defaults set by Drupal Core:

• Set the Syslog identity value to 'drupal'
• Set the Syslog facility to: `LOG_LOCAL0`

• Set the Syslog format to: `!base_url|!timestamp|!type|!ip|!request_uri|!referer|!uid|!link|!message`
