Fedora 30 : Detect hardware issues.

You can detect your hardware and read the health of your system using many commands and tools.
Today I show you these tools: lm_sensors-sensord.x86_64 and lshw.

[root@desk mythcat]# dnf install lm_sensors-sensord.x86_64

Installed:
  lm_sensors-sensord-3.5.0-6.fc30.x86_64       rrdtool-1.7.2-1.fc30.x86_64      
  libdbi-0.9.0-13.fc30.x86_64

First, use this command to select and setup the sensors:

[root@desk mythcat]# sensors-detect
# sensors-detect revision $Revision$
# System: Gigabyte Technology Co., Ltd. Z68P-DS3
# Kernel: 5.2.13-200.fc30.x86_64 x86_64
# Processor: Intel(R) Celeron(R) CPU G1620 @ 2.70GHz (6/58/9)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES
...

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

Driver `it87':
  * ISA bus, address 0x290
    Chip `ITE IT8728F Super IO Sensors' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): YES
Unloading i2c-dev... OK

The output of sensors can be show like this:

Using the lshw tool:

[root@desk mythcat]# lshw
desk                        
    description: Desktop Computer
...

The tool extracts detailed information on the hardware configuration of the machine and output is shown like HTML, JSON or SQLite database, see the help:

       lshw [ -version ]

       lshw [ -help ]

       lshw [ -X ]
