Enabling Application Core Dumps
Application core dumps are disabled by default. A core dump file can be very large. Core dumps are stored in the local flash.
To enable core dumps, use the following command.
Enable RPM core dumps and specify the shutdown mode.
CONFIGURATION mode
logging coredump server
When you enable this command to allow the system to automatically upload application core dumps to an FTP server, you are
required to enter a password. Use the password of the FTP server where the core files are being moved. The password can be
up to 15 alphanumeric characters only; no special characters are allowed. After you enter the password, an FTP URL is created
with the credentials in the operating system. The CLI monitors application core dumps in the unit. Any application core dumps
that occur are automatically uploaded to the FTP server.
To undo this command, use the no logging coredump server command.
Mini Core Dumps
Dell Networking OS supports mini core dumps for kernel crashes. The mini core dump applies to Master units.
Kernel mini core dumps are always enabled. The mini core dumps contain the stack space and some other very minimal
information that can be used 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://
CORE_DUMP_DIR directory. The kernel mini core filename format is f10StkUnit<stack_unit_no>.kcore.mini.txt.
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.
