Ubuntu box crashes quite often

  • 772

I have a ubuntu 11.04 box running 24/7. It started to crash any couple of days recently.
I checked in kern.log, dmesg... but did not find anything there. Is there a specific place where shutdown reason (temperature, or whatever) are logged ?

  1. Do you have monitoring for you server?

    Actually, my answer to this would be: Please add monitoring for your server if you do not have. You should have at least: cpu load, cpu temp, disk usage, disk temp, disk IO, NIC traffic.

    Just chose one you can easily install, maintain. Any or a combination of these would work (not a complete list): mrtg, cacti, zenoss, nagios etc.; with proper plugins, snmp or rrd scripts.

    Check the charts for clues after a crash happens.

  2. I have a unbuntu 11.04 box running 24/7 for something like 2 years now

    You do realize this is impossible, right ?

    Either it's not 2 years, or you upgraded it.

    CHeck the upgrade logs for any issues.
