How to set different error levels in symfony logging?

In Symfony, you can set different error levels in logging by configuring the Monolog logger in your application's configuration files. Here's how you can set different error levels:

1. Open your Symfony project's configuration file (e.g., app/config/config.yml).
2. Find the section where the Monolog logger is configured. By default, Symfony uses the monolog service to handle logging.
3. To set different error levels, you can specify the minimum level of log messages that should be logged. You can do this by adding a handlers section under the monolog configuration, and then adding a level parameter to specify the minimum level. For example, to only log critical errors and higher, you can set the level to critical:

1
2
3
4
5
6

monolog:
    handlers:
        main:
            type: stream
            path: "%kernel.logs_dir%/%kernel.environment%.log"
            level: critical

1. There are several logging levels available in Monolog, such as debug, info, notice, warning, error, critical, and alert. You can choose the appropriate level based on the severity of the errors you want to log.
2. Save the configuration file and clear the cache by running php bin/console cache:clear in your terminal.

By setting different error levels in the Monolog configuration, you can control which types of messages are logged to the specified log file. This can help you manage and troubleshoot errors more effectively in your Symfony application.
