How to perform hardware monitoring and troubleshooting on Linux systems

How to perform hardware monitoring and troubleshooting on Linux systems requires specific code examples

Abstract:
As an open source operating system, Linux is widely used in various computing devices and servers. It is critical for system administrators to understand how to monitor and troubleshoot hardware. This article will introduce how to use the tools and commands provided by the Linux system to monitor hardware status, and how to use troubleshooting techniques to solve common hardware problems. In addition, we will also provide some specific code examples for readers to understand better.

1. Hardware Monitoring Tools and Commands
   Some commonly used Linux hardware monitoring tools and commands include:
2. lm-sensors: Utility for monitoring system sensors and hardware sensors. It provides real-time information on CPU temperature, fan speed, power supply voltage, and more.
3. smartctl: A tool for monitoring and controlling S.M.A.R.T hard drive parameters. It can provide information such as the health status and remaining life of the hard drive.
4. lspci: Lists the system’s PCI device information, including network cards, graphics cards, sound cards, etc.
5. lsusb: Lists device information connected to the USB port.
6. dmidecode: Get detailed information about the system hardware, such as BIOS version, motherboard model, memory specifications, etc.
7. Using Linux hardware monitoring tools
   The following are some sample codes for using Linux hardware monitoring tools:

a. Use lm-sensors to obtain CPU temperature data:

# 安装lm-sensors
sudo apt-get install lm-sensors

# 加载核心模块
sudo sensors-detect

# 查看CPU温度
sensors

b. Use smartctl to obtain hard disk information:

# 安装smartmontools
sudo apt-get install smartmontools

# 查看S.M.A.R.T硬盘信息
smartctl -a /dev/sda

c. Use lspci to list PCI device information:

# 列出PCI设备信息
lspci

d. Use lsusb to list USB device information:

# 列出USB设备信息
lsusb

e. Use dmidecode to obtain hardware details:

# 获取系统硬件信息
sudo dmidecode

3. Hardware fault handling technology
   Hardware fault handling is the key to solving hardware problems. The following are some common hardware failure handling techniques:

a. Compliant error prompts: When hardware fails, the system may give corresponding error prompts. Read the error message carefully and follow the prompts for corresponding troubleshooting.

b. Reconnect hardware devices: Sometimes, hardware failure can be caused by loose device connections. Try reconnecting the hardware device to see if the problem is resolved.

c. Replace hardware: If the above method does not solve the problem, you may need to replace the damaged hardware device. Before replacing hardware, make sure to back up important data.

d. Contact vendor support: When encountering a serious hardware failure, it is best to contact the hardware vendor or manufacturer's support team for professional help and advice.

Conclusion:
This article introduces how to use hardware monitoring tools and commands of Linux systems to monitor hardware status, and provides some specific code examples. In addition, some common hardware troubleshooting techniques are also introduced. Mastering these knowledge and skills will help system administrators better monitor and deal with hardware problems in Linux systems and ensure the stability and reliability of the system.
