What do i look for in logs - eviltoast

Hi everyone

My proxmox server is crashing daily. And I’ve been checking the logs. But the thing is. What do I look for? Syslog, kern and daemonlogs. I would like to fix this problem. Need advice ! Thanks

    When I look a the logs, I’m mostly looking for as least knots as possible, but also to make sure they are cedar, pine, or oak depending on the project.

    Oh shit, this isn’t the carpentry community. NVM then

    grep -Ri ‘error/|warning’ /var/log/

    Then you can further pipe ‘grep’ or ‘grep -v’ based on what you see or for a specific time.

    On Linux systems running systems I usually use the journalctl tool to look at messages. Ex.

    journalctl --list-boots journalctl --since=“2012-10-30 18:17:16”

    Looking for anything obvious.

    You know what the various logs are, that’s good to help out. So you have any crash dumps enabled? I think on Debian (what promox is based on), you have to install kdump tools and reboot. Then it should cause a the kernel to log a dump file you can read with crash if it’s a kernel crash and not something else.

    A good place to start because it’s a likely culprit is anything mentioning “OOM” (which refers to Out Of Memory)
