Drupal's log system
To understand the limitations of the Drupal log and the improvements introduced by Monolog, it is first necessary to know what both systems consist of.
What does Drupal provide us with?
The most commonly used logging system that Drupal offers is dblog, a tool that logs events and errors that happen on the site, storing these logs directly in the system's database. Although dblog is useful for its accessibility and simplicity of integration, it can present significant performance issues when dealing with a high amount of traffic or frequent and massive logs.
On the other hand, there is syslog, a more robust alternative for log management. It allows system administrators to collect and store log messages on a dedicated server, thereby centralizing logs from multiple systems in a single location. However, it can be more complex to configure and is less accessible for users with limited system knowledge.
What if I don't want everything to go to the same place?
Drupal natively only allows you to choose one way to manage all logs. Sometimes, we need logs to be stored differently depending on their source. For this purpose, Monolog allows the management of each channel, enabling the processing of messages, selection of their format, and their destination.
