QPR Knowledge Base 2019.1
In the Server log settings section you can define the folder in which the log files are stored. By default this is C:\ProgramData\QPR Software\QPR 2019\2019.1\Servers\Logs, but you can change it by clicking the 
Browse button and then locating the desired path. By clicking the 
Open log folder button you can view directly the contents of the folder that you have defined as the folder for storing the log files.
You can define the maximum size of log files by entering the value in the Maximum log file size (MB) field separately for each server. The value is set in megabytes (MB), and by default the value is 25 MB. If the maximum log file size is reached, new entries will be written over the oldest entries.
You can also choose whether to force different logging options. The options are:
•Force normal trace mode for all products: All server components and Web Application Server plugins will use the normal logging mode.
•Force full trace mode for all products: All server components and Web Application Server plugins will use the full trace logging mode.
•Custom trace mode for each product: With this option you can select the logging mode individually for the server components.
In the Normal mode only errors are written to the log file. In the Full Trace mode all server messages are written to the log file. In most cases the Normal mode should be sufficient.
You can enable audit logging for QPR Metrics Server and QPR BizArchitecture Server by selecting the appropriate Logging enabled radio button. When the audit log is enabled, all QPR Metrics Server measure changes are recorded into the SCSAudit.txt file and all QPR BizArchitecture Server operations to a model into the PGSAudit.txt file located in the "Audit" folder under the log files folder defined in the Folder field above. For more details about the audit log, refer to Audit Log chapter in QPR Administrator's Guide.
The User Audit Logging for each QPR Server can be disabled and enabled by selecting Logging disabled, Basic logging enabled or Full logging enabled. For more details about the user audit log, see the User Audit Log chapter in QPR Administrator's Guide.
For details about the Performance log settings, see the description for PerformanceLog key in Appendix A in QPR Administrator's Guide.
