What will be the result when logging with category1.eu if category1 is enabled for WARN level?

When logging with the specified category, if category1 is enabled for WARN level, any log messages that meet or exceed the WARN level will be captured. In Salesforce B2C Commerce, the logging system allows for different prefixes to be added to log files based on the configured logging levels and categories.

In this case, since category1 is specifically set for the WARN level, the log messages that are written would reflect this categorization. The prefix custom-loggerFile is used when logs from a custom category are written, which is applicable here. This indicates a structured approach to categorizing logs based on their source or intended purpose.

The prefix serves to clearly identify the logs associated with that specific category when reviewing log files, effectively helping in managing and debugging the logs based on their severity level. The prefix custom-loggerFile would thus ensure that logs written under this category are easily distinguishable and traceable, aligning with best practices in log management.
