Debug logging

Debug logging can be used to identify issues with connections. It provides debug level details for each connections as well as the time each step took (e.g. parsing time, scan time, response time). It also tracks the number of active connections.

Important notes

Debug logging is not designed to be constantly enabled. It should only be used for investigating issues for short periods of time.

Keeping it enabled permanently may impact performance. If running for too long, the log file can become very large and significantly reduce the available disk space.

In each case below, both logfile and loglevel settings must be set for the changes to be active.
