Usage guidelines

For diagnostics or troubleshooting, you can use separate display commands to collect running status data module by module or use the display diagnostic-information command to bulk collect running data for multiple modules.

This display command does not support the | by-linenum option, the > filename option, or the >> filename option. However, this command asks you whether you want to save the output to a file or display the output on the screen. The file used to save the output is automatically compressed to save storage space.

To successfully save the statistics to a file, make sure the directory for saving core files on the active MPU or global active MPU is not NULL and is accessible. To display the directory, use the display exception filepath command.

Before executing the display diagnostic-information command, perform the following tasks:

• Use the display cpu-usage command to display CPU usage statistics.

• Use the display memory command to display memory usage statistics.

Make sure the CPU usage is not 100% and the memory usage is not higher than 90% before executing the display diagnostic-information command.
