Example of When No Core File Is Generated

When a power outage occurs, no kernel crash core file is generated. To view the messages log file, use the following CLI command:

user@host> show log messages

Sample Output

user@host> show log messages

Aug 15 15:35:59 host /kernel: savecore: Router rebooted. Cause unknown....

Aug 15 15:35:59 host savecore: Router rebooted. Cause unknown....

What It Means

The kernel checks for a core dump file when the router reboots.
