Usage guidelines

CAUTION

CAUTION:

Output of excessive debugging messages increases the CPU usage and downgrades the system performance. To guarantee system performance, enable debugging only for modules that are in an exceptional condition.

 

The system sends generated debug messages to the device information center, which then sends the messages to appropriate destinations based on the log output configuration. For more information about the information center, see System Management Configuration Guide.

Examples

# Enable debugging for the device management module.

<Sysname> debugging dev
