Guide to Reading CPU, RAM, and DISK Metrics When Running Commands on Linux

During the management of a VPS or server, monitoring and understanding system metrics is extremely important. CPU, RAM, and DISK metrics directly reflect operating performance, helping you address overload or resource bottleneck issues in a timely manner. That is why the companyVPTSsends you a detailed guide on how to read CPU, RAM, and DISK metrics when running commands on Linux — helping you manage systems effectively, stably, and save operational costs.

Check CPU specifications

Check CPU configuration

Command 1: 

lscpu

Specification explanation:

School	Meaning
Architecture	CPU architecture (x86_64, ARM, etc.)
CPU(s)	Total logical cores (including Hyper-Threading if applicable)
Thread(s) per core	Threads per core
Core(s) per socket	Number of physical cores per socket
Socket(s)	Number of physical CPUs (sockets) on motherboard
Vendor ID	Manufacturer (Intel, AMD, etc.)
Model name	Specific CPU name (e.g., Intel(R) Xeon(R) Platinum 8272CL)
CPU MHz	Current clock speed of each core
CPU max MHz	Maximum achievable CPU speed
Virtualization	Virtualization support (VT-x, AMD-V)
NUMA node(s)	Number of memory nodes (useful when optimizing multi-CPU systems)

• As the image above clearly explains when checking parameters

Command 2:

top

or

htop

• Explanation:

• %Cpu(s):indicates CPU usage:

• us: user (application)

• sy: system (kernel)

• id: idle

• wa: waiting for I/O

• st: stolen (taken by hypervisor)

Check RAM

Command:

free -h

Specification explanation:

School	Meaning
total	Total physical RAM capacity
used	Used RAM (including cache)
free	Free unused RAM
shared	RAM shared between processes
buff/cache	RAM used as cache and buffer (will be freed when needed)
available	Actual available RAM for applications

Check disk (DISK)

Check storage capacity of each partition:

df -h

Column	Meaning
Filesystem	Device / partition name
Size	Total capacity
Used	Used
Avail	Available
Use%	Usage rate
Mounted on	Mount directory

After surveying and inspecting resources at, you have mastered the technical specifications of Linux operating systems—from hardware configurations to real-world operational capabilities.

CONCLUSION

Through the guide on reading CPU, RAM, and DISK metrics when running commands on Linux byVPTS, you can easily check system performance and monitor resource status accurately. Keeping track of these metrics helps you proactively detect overload early, optimize server performance, and reduce the risk of service interruptions. This is an important step to ensure your VPS operates stably, securely, and cost-effectively for your business.
