What is the minimum total file usage required for the file removal rules in {log-dir}/process?

The correct answer indicates that the minimum total file usage required for the file removal rules in the specified directory is 300 MB. This threshold is not arbitrary; it is set to optimize storage management and performance within the Dynatrace environment.

When managing log files in an environment that handles extensive monitoring data, having a defined limit helps ensure that the system does not become inundated with excessively large or numerous log files. Setting this minimum usage at 300 MB allows for sufficient data retention for troubleshooting and analysis while also enabling the system to automatically manage and recycle older files as newer log entries are generated. This keeps the log directory from becoming overwhelming and ensures that the relevant logs remain accessible for a reasonable period without taking up excessive disk space.

By enforcing this limit, Dynatrace balances the need for historical log data against the practicalities of system storage and performance, facilitating better resource management and operational efficiency.
