What is defined by the FilesInGroup parameter in the configuration file?

The FilesInGroup parameter in the configuration file specifically defines the maximum number of files that a process group can open. This is crucial for managing resources effectively within a system, as each process consumes file handles. Setting a limit helps prevent issues related to exceeding system limits on file descriptors, which can lead to errors and performance degradation. By capping the number of files, the system can maintain stability and ensure that processes do not exhaust the available resources, allowing for smoother system operations and better performance overall.

Other parameters like the total size of log files, rotation rate, or minimum number of logs are related to different aspects of log management and do not pertain to the limitation on the number of files a process can handle, which is precisely what the FilesInGroup parameter addresses.
