How to see Logs ? Proxmox crash alternate

[Philou15]

Hye

Sorry for my english,i'm french.

I Have Proxmox 5.3.8 on NUC - SSD 32 Gb - 4GB
I Have test my ram with MEMORY TEST its ok.

But i use my proxmox for one VM, Jeedom.

Its ok, but then i want to ping every hours google server for test my internet proxmox crash.

I have test with PHOLE, after 1 days proxmox crash, so i think it a request on ethernet ?

So That the log for see the problem ?

I Can use SSH if need.

Tks for your help.

Hi,

Normal you should see something in the syslog.
/var/log/syslog

But I would also enable the persistent journald log

mkdir /var/log/journal

Hye

Sorry but i noob in this...

It not working i have tape this

I'm root login

Tks

root@proxmox:~# /var/log/syslog
-bash: /var/log/syslog: Permission denied
root@proxmox:~# mkdir /var/log/journal
root@proxmox:~# /var/log/syslog
-bash: /var/log/syslog: Permission denied
root@proxmox:~#

Try:
# less /var/log/syslog

To debug anything you will need some basic Linux knowledge, if you are interested in the topic I bet there is some french guide out there as well.

Tks, its works but no history,

Morning proxmox crash and no ethernet acces, so i power off witch socket and power on,

so logs begin like morning power off/on

Tks
