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. The mini core dump applies to Master, Standby,
and Member units.
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.
When a member or standby unit crashes, the mini core file gets uploaded to master unit. When the master unit crashes, the mini core file
is uploaded to new master.
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.
