The Essential Commands
# Quick summary
lscpu | grep -E "Model name|CPU\(s\)|Thread|Core|Socket"
# Example output:
# Model name: Intel Xeon E5-2680 v4
# CPU(s): 28
# Thread(s) per core: 2
# Core(s) per socket: 14
# Socket(s): 1
Understanding the Output
| Field | Meaning | Example |
|---|---|---|
| Model name | CPU model | Xeon E5-2680 |
| CPU(s) | Total logical processors | 28 |
| Thread(s) per core | Hyperthreading | 2 = HT enabled |
| Core(s) per socket | Physical cores | 14 |
| Socket(s) | Physical CPUs | 1 |
Total logical CPUs = Sockets × Cores × Threads
Why This Matters
Understanding CPU info helps you:
- Know your load average limit (should be < logical CPUs)
- Plan process limits (one CPU-bound process per core)
- Verify VM allocation matches reality

FAQ: Common Questions About CPU Information Monitoring
How often should I check CPU information?
We recommend checking CPU information once weekly or monthly. CPU specifications rarely change unless hardware is replaced. More frequent checks may be needed after hardware changes or when troubleshooting. Adjust frequency based on your hardware change frequency and requirements.
Can I monitor CPU temperature?
CPU temperature monitoring requires additional tools like sensors or hardware-specific utilities. This basic recipe focuses on CPU specifications. For temperature monitoring, use dedicated temperature monitoring tools or Zuzia.app's temperature monitoring features if available.
What if CPU information changes?
You'll receive notifications when CPU information changes are detected. This could indicate hardware replacement or configuration changes that need verification. Review change details, verify hardware changes, update documentation, and ensure configurations are correct. Hardware changes may require system restarts or configuration updates.
Can I compare CPU info across servers?
Yes, you can add this task to multiple servers and compare CPU specifications to ensure consistent hardware configurations or plan upgrades. Compare CPU models, core counts, frequencies, and architectures across servers. Use comparisons to standardize hardware and plan fleet-wide upgrades.
What's the difference between CPU cores and threads?
CPU cores are physical processing units, while threads are logical processing units. Hyperthreading allows multiple threads per core. Monitor both cores and threads to understand processing capabilities. More cores and threads generally mean better parallel processing performance.
How do I interpret CPU frequency?
CPU frequency indicates processing speed in MHz or GHz. Higher frequency generally means faster processing, but modern CPUs use frequency scaling to optimize power and performance. Monitor both base and maximum frequencies to understand CPU capabilities.
Can I track CPU information over time?
Yes, Zuzia.app stores historical data, allowing you to track CPU information over time. Review historical data to identify changes, compare current vs. historical specs, detect hardware replacements, and maintain hardware inventory. Historical data helps understand hardware evolution.
How does AI help with CPU monitoring?
If you have Zuzia.app's full package, AI analysis can detect CPU patterns automatically, identify optimization opportunities, predict capacity needs, suggest hardware upgrades, and provide insights for improving server performance. AI helps you understand CPU usage patterns and plan capacity upgrades.
What if I have virtual machines?
Virtual machines may show virtual CPU information rather than physical CPU specs. Monitor virtual CPU allocation, compare with physical host CPUs, and plan virtual CPU resources accordingly. Virtual CPU monitoring helps optimize VM resource allocation.
Can I export CPU information data?
Yes, Zuzia.app allows you to export monitoring data. Export data for analysis, reporting, inventory management, or hardware investigation. Use exported data to analyze CPU patterns, create hardware reports, and plan capacity upgrades.
