Log messages are essential tools for recording data related to access, errors, and the operational status of an application. These messages are typically saved to a file on the server, a database, or online storage, and can also be transferred to a remote server for later analysis.

There are different types of logs:

– Information logs: These provide details about the overall operation of the application, including information about the parameters used, the data manipulated, and the events triggered.

– Warning logs: Their role is to alert users to potential problems in the application code. These logs can contain valuable information about variable values, detected errors, and exceptions that occurred.

– Error logs: These logs report anomalies in the code that compromise the proper functioning of the application. They generally provide information about exceptions encountered, technical incidents, and observed malfunctions.
