Displaying Diagnostic Information


When the system experiences a fault or during routine maintenance, you can view diagnostic information to collect the running information of all modules.

Diagnostic information is mainly used for fault locating. Collecting diagnostic information may affect system performance. For example, it may increase CPU usage. Therefore, collecting diagnostic information is not recommended when the system is running normally.
