Universal Bash script for gathering system information and performing safe hardware tests on Linux hosts.

This script reports hardware details and performs basic stress tests on CPU, RAM, disk I/O, and temperature, with logging and automatic dependency installation.

• Operating system and version
• CPU model, cores, thread count
• RAM total and usage
• Disk information (model, size, mount points)
• Network interfaces (name, MAC, IP)
• Virtualization detection
• Software and hardware RAID detection

• Quick Test — short CPU and RAM test
• Full Test — Quick plus disk read test (safe)
• RAM Integrity Test — using memtester
• Thermal Stress Test — CPU stress with temperature monitoring

All output is captured into a log file under /var/log with timestamp for audit and support.

The script auto-detects the package manager and installs missing tools:

• lm-sensors
• memtester
• stress-ng
• pciutils

Support for:

• apt
• dnf
• yum
• zypper

$ ./stress.sh
Log file: /var/log/hw_diagnostics_20260110_153045.log
...

• Linux system with Bash
• Must run as root to install dependencies and access hardware information

Clone the repository:

git clone https://github.com/bazzelio/stress-test.git
cd stress-test/linux-hw-diagnostics
chmod +x stress.sh

Run the script:

./stress.sh

or explicitly with Bash:

bash stress.sh

Do not use:

sh stress.sh   # Not supported

1) Quick test
2) Full test
3) RAM integrity test
4) Thermal stress test
5) Exit

Choose the test you need from the interactive menu.

• Disk read-only test — does not modify data
• RAM integrity test is live, not boot-time memtest
• Stress tests may heat CPU — thermal tests stop on reaching temperature limits
• Recommended to run in a maintenance window on production systems

All outputs and test results are logged:

/var/log/hw_diagnostics_YYYYMMDD_HHMMSS.log

This log is helpful for:

• Support requests
• Incident analysis
• Automation and parsing

Works on most Linux distributions, including:

• Debian / Ubuntu
• CentOS / RHEL / AlmaLinux / Rocky
• openSUSE
• Bare-metal servers
• Virtual Machines

• Online RAM tests are not as thorough as boot-time memtest86
• Long SMART disk tests are not included to avoid long delays
• Hardware RAID health depends on vendor utilities
