Enabling Application Core Dumps
Application core dumps are disabled by default.
A core dump file can be very large. Due to memory requirements the file can only be sent directly to an FTP server; it is not
stored on the local flash.
To enable full kernel core dumps, use the following command.
Enable stack unit kernel full core dumps.
CONFIGURATION mode
logging coredump server
To undo this command, use the no logging coredump server command.
Mini Core Dumps
Dell EMC Networking OS supports mini core dumps on the application and kernel crashes.
Application and kernel mini core dumps are always enabled. The mini core dumps contain the stack space and some other
minimal information that you can use to debug a crash. These files are small files and are written into flash until space is
exhausted. When the flash is full, the write process is stopped.
A mini core dump contains critical information in the event of a crash. Mini core dump files are located in flash:/ (root dir).
The application mini core filename format is f10StkUnit<Stack_unit_no>.<Application name>.acore.mini.txt. The kernel mini core
filename format is f10StkUnit<Stack_unit_no>.kcore.mini.txt. The following are sample filenames.
The panic string contains key information regarding the crash. Several panic string types exist, and they are displayed in regular
English text to enable easier understanding of the crash cause.
