Logging 101: A technical deep dive

Written by Johan Moormann | Dec 5, 2023 10:14:00 AM

Loggers serve as indispensable tools to monitor code behavior and diagnose customer-reported bugs. Whether encountering unexpected data or unexplained exceptions, implementing a logger ensures clarity for future incidents. However, logger implementation practices vary significantly across developers. From default logger services to customized Monolog wrappers or even rudimentary file handle append methods, each approach offers distinct outcomes.

Monolog mastery

Shopware/Symfony integrates Monolog—a PHP logging library, standardizing logging practices. Its inherent utility in Shopware, built on Symfony, leverages multiple handlers and processors for robust data gathering and storage. While Shopware utilizes a standard Monolog setup, we prefer a tailored approach.

Setup essentials

Leveraging Symfony’s service container, we streamline logger creation using XML—an approach consistent with Shopware documentation.

[XML code snippet]
<service id="demo.logger" class="Symfony\Bridge\Monolog\Logger">
<argument>Demo</argument>
</service>
[End of XML snippet]

This basic setup merely initializes the logger—additional functionalities will follow.

Log management fundamentals

Unveiling Monolog’s versatility in handling logs, especially in file management, we focus on a basic rotating file handler. Designed to create a new log file daily, it ensures a structured logging process.

[XML code snippet]
<service id="demo.logger.handler.file" class="Monolog\Handler\RotatingFileHandler">
<argument>%kernel.logs_dir%/demo_%kernel.environment%.log</argument>
</service>
[End of XML snippet]

Extending this, we can limit the number of log files retained in the directory by introducing a second argument in the handler.

[XML code snippet]
<service id="demo.logger.handler.file" class="Monolog\Handler\RotatingFileHandler">
<argument>%kernel.logs_dir%/demo_%kernel.environment%.log</argument>
<argument>14</argument>
</service>
[End of XML snippet]

Integration chronicles

Connecting our logger and handler instances involves passing the handler to the logger, achieved through the logger’s second argument—presented as a Symfony collection.

 
[XML code snippet]
<service id="demo.logger" class="Symfony\Bridge\Monolog\Logger">
<argument>Demo</argument>
<argument type="collection">
<argument type="service" id="demo.logger.handler.file"/>
</argument>
</service>
[End of XML snippet]

The XML compilation encapsulates our logger setup, ensuring precise recording and organization of crucial events. That’s it. We now have a logger that can handle our logs by writing them to a file. The entire XML file should look something like this:

[XML code]
<?xml version="1.0" ?>

<container xmlns="http://symfony.com/schema/dic/services"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="https://symfony.com/schema/dic/services https://symfony.com/schema/dic/services/services-1.0.xsd">
<services>
<defaults public="true"/>

<service id="demo.logger" class="Symfony\Bridge\Monolog\Logger">
<argument>Demo</argument>

<argument type="collection">
<argument type="service" id="demo.logger.handler.file"/>
</argument>
</service>
</services>
</container>
[end of XML code]
