Default Odd server restart

Hello gurus,

I'd like to know of a way to check why was my server restarted, who or what caused this restart, was it power short-edge or caused interactively by user,

Running who -b outputs the following:
Code:
system boot  2010-04-27 04:03
Checking /var/log/messages that time all I see is:
Code:
...
Apr 27 03:13:15 localhost xinetd[8893]: EXIT: vnetd status=0 pid=17912 duration=0(sec)
Apr 27 03:13:15 localhost xinetd[8893]: EXIT: vnetd status=0 pid=17909 duration=0(sec)
Apr 27 03:13:28 localhost xinetd[8893]: START: vnetd pid=17951 from=172.22.0.5
Apr 27 03:13:28 localhost xinetd[8893]: START: vnetd pid=17952 from=172.22.0.5
Apr 27 03:13:28 localhost xinetd[8893]: EXIT: vnetd status=0 pid=17952 duration=0(sec)

Apr 27 04:04:08 localhost kernel: ACPI: LAPIC (acpi_id[0x03] lapic_id[0x01] enabled)
...
Please suggest how can I collect more info regarding this restart...

Do you have munin installed? That might give you some info on what has happened.

I'd install munin then. That might help you to detect problems with your system resources that might cause a reboot.

If you use user auditing/process auditing that could help you detect if a user is causing the reboot.
