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.
Examples
