How can you identify NUMA node configuration on your system using available tools?
Check disk latency using iostat. How would you analyze write latency?
Use pidstat to monitor process-specific resource usage. How can you identify CPU-hogging processes?
Analyze memory performance using sar -r. How do you determine if the system is swapping?
Identify the cause of high load average using uptime, top, and vmstat. Provide a workflow.
You suspect CPU resource contention on a RHEL 9 system. Use vmstat to monitor CPU usage and interpret the output to determine if the system is CPU-bound.
