system crash logging

almarto — Sun, 10 Apr 2016 06:52:18 GMT

Hi all,

I am trying to debug a system crash and would like to access information on /var/log/kern.log and /var/log/messages.

The systems has syslogd and klogd running in background with the following option:

690 root 2820 S /sbin/syslogd -n -O /var/log/messages

693 root 2820 S /sbin/klogd -n

We the system restart due to a system crash, /var/log/kern.log does not exist (actually I guess it is never created) and /var/log/messages has new data after rebooting.

This is the content of /var/log after system crash and reboot, I think I can not find any kernel issues into these files:

root@ccimx6sbc:/var/log# ls -ls

20 -rw-r--r-- 1 root root 18203 Apr 8 10:10 Xorg.0.log

4 -rw-r--r-- 1 root root 2600 Apr 8 10:10 Xsession.log

0 -rw-r--r-- 1 root root 0 Apr 8 10:10 acpid.log

20 -rw-r--r-- 1 root root 18867 Apr 8 10:10 dmesg

72 -rw-r--r-- 1 root root 72168 Apr 9 23:48 messages

204 -rw-r--r-- 1 root root 204864 Apr 9 10:17 messages.0

2080 -rw------- 1 root root 2128268 Apr 9 07:16 vsftpd.log

4 -rw-rw-r-- 1 root root 2688 Apr 9 22:44 wtmp

Could anybody give any hint on how to log kernel issues to try to solve my crash problem? I would like to monitor last session kernel events after system reboot.

Thank you in advance.

BR,

alvaro
