What is the purpose of log files?

Is it OK to delete log files?

Yes, log files can be safely deleted. Next time a log file needs to be appended to and is missing, it will be created (don't delete the actual Logs folder itself though).

What is the importance of log?

Logs are also useful to detect common mistakes users make, as well as for security purposes. Writing good logs about a user's activity can alert us about malicious activity. It is important that logs can provide accurate context about what the user was doing when a specific error happened.

Why do you want to keep logs?

The reason we need logs is because they hold information that can't be found anywhere else. For example, say you added something to a domain class but you forgot to run the migration. This will probably cause some problems.

What is stored in log files?

Logs files are a historical record of everything and anything that happens within a system, including events such as transactions, errors and intrusions.
