Server settings in log4net.config

QPR ProcessAnalyzer uses the log4net component (https://logging.apache.org/log4net/) for logging, allowing to flexibly define what is logged and where the logs are stored. For example, the following settings can be set in the log4net.config file (located in the bin folder in the server application files):

• log4net > appender > maximumFileSize: Maximum size of the log file. When the maximum size is reached, the log writing continues in a new file, and the old file is archived. The default setting is 100MB. (https://logging.apache.org/log4net/log4net-1.2.13/release/sdk/log4net.Appender.RollingFileAppender.MaximumFileSize.html)
• log4net > appender > maxSizeRollBackups: Maximum number of archived log files that are stored. When the maximum file size is reached and new file is created, the oldest archived log file is removed if the maximum number of archived files is reached. The default setting is 1. (http://logging.apache.org/log4net/log4net-1.2.15/release/sdk/html/P_log4net_Appender_RollingFileAppender_MaxSizeRollBackups.htm)
• log4net > appender > lockingModel: By default, the server log works in the ExclusiveLock mode, i.e. the log file is reserved by the QPR ProcessAnalyzer process for the entire time QPR ProcessAnalyzer is running. Thus it's not possible to edit or delete log files during that time.
