How to Check Hardware Errors

Prerequisites

Before checking hardware errors, make sure you have:

• SSH access to your VPS
• Root or sudo privileges

Method 1: Check Kernel Ring Buffer (dmesg)

Connect to your VPS:

ssh hxroot@YOUR_SERVER_IP -p 22

dmesg | grep -i error

dmesg | grep -i fail

dmesg | grep -i hardware

Method 2: Check System Logs

sudo journalctl -p 3 -xb

Shows priority 3 (error) messages.

sudo grep -i "hardware error" /var/log/syslog

Method 3: Check MCE (Machine Check Exceptions)

sudo mcelog --client

If mcelog is installed and hardware supports it.

Method 4: Check Disk Health (SMART)

For physical disks (may not work on VPS):

sudo apt install smartmontools -y
sudo smartctl -a /dev/vda

Method 5: Check Memory Errors

sudo grep -i "memory error" /var/log/syslog

Method 6: Check CPU Errors

sudo grep -i "cpu error" /var/log/kern.log

Method 7: Check for PCIe Errors

sudo lspci -vvv | grep -i error

Automated Hardware Error Reporting

Install and configure edac-utils for ECC memory:

sudo apt install edac-utils -y
sudo edac-util -v
