Verifying Configuration Results
After the NMI configuration is complete, trigger an NMI for verification.
Open the terminal and run the echo c > /proc/sysrq-trigger command to force the system to crash so that the system can restart the kdump kernel and access the kdump process. After a period of time, restart the OS and check whether the vmcore files are generated in /var/crash.
The default vmcore file directory is /var/crash/%HOST-%DATE/, which stores two vmcore files: vmcore and vmcore-dmesg.txt.
