Collection Mode Description

Run the following command to collect device logs:

msnpureport

• After the command is executed, a timestamp folder is generated in the current directory. Dump the slog and hisi_logs folders in the timestamp directory to the collection directory/device_log directory.
• If log collection fails, rectify the fault by referring to "FAQs" > "What Do I Do If Log Flush Fails?" in CANN Log Reference.
