Hi Friends,
I want to get kernel crash log in /var/log/messages to take back up.
I am doing in run script like below
cat /var/log/messages > /home/Crash.log
sleep 1
klogd &
syslogd &
so now after board is booted i will get previous messages in /home/Crash.log and present messages in /var/log/messages. I am creating kernel panic using "echo c > /proc/sysrq-trigger"
after reboot i am getting the kernel log up to last message before panic, so how can i get crash details also, for this am i need to enable any configurations in kernel menuconfig. If any one knows kindly give information.
Thanks & Regards,

You can add into /etc/sysctl.conf file the line like this:
kernel.core_pattern = /var/log/core
Have a great day,
Victor

Hi Victor,
Thank you , I added kernel.core_pattern = /var/log/core in /etc/sysctl.conf and i created panic using echo c > /proc/sysrq-trigger but after reboot i have not seen any messages in /var/log/core or /var/log/messages. To get crash log in to file we need to select any kernel configurations from menuconfig.
Thanks & Regards,
