Modifying Logger settings
You can configure the logging level for each of the logger keys listed for the Loggers component.
For troubleshooting you may want to increase the logging level to generate more information in
the log file for use in debugging a problem. Setting all loggers to a high verbose level of logging
is not recommended because it can lead to a shortage of system storage space very quickly.
NOTE: If the controller is restarted or if the virtual machine is rebooted, the log levels for all
loggers revert back to INFO.
The log levels from most verbose to least verbose are: ALL, TRACE, DEBUG, INFO, WARN,
ERROR, OFF.
For configuration purposes the loggers are grouped into categories listed as keys you can modify.
NOTE: You can also use the python script /opt/sdn/scripts/postinstall/
config_sdn.py to configure logging levels for individual loggers on a controller. For details on
using this script, see the HPE VAN SDN Controller Installation Guide.
1. On the Configurations screen in the System tab, select Loggers. You can use the expand
icon to view the logging levels currently configured.
2. Click Modify.
The Modify System Configuration dialog box is displayed for the Loggers component. For
