system crash logging

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
