Change Log Events and Thresholds

Loggers and appenders determine the content in the log files of the SAS Visual Process Orchestration Server logs. The loggers and appenders are defined in log configuration files, such as install-path/etc/dmserver.log.xml.

Appenders specify the log output destination. Loggers specify log event types and thresholds. If a logger lists a given log event, then those events are recorded in the log file. The threshold value determines the amount of information that is captured in the log file for each event. The available threshold levels are ranked as shown in the following diagram.

The default threshold level capture most of the events that you will need to diagnose server problems. However, should there be a need to increase logging events and threshold levels, contact your SAS technical support representative for assistance.

Altering threshold levels above INFO when the server is operational in a production environment is discouraged since this can result in a reduction in server performance.

When you change a log configuration file, you are required to restart the server.
