Memory and CPU Performance Tools
Utilize tools like `vmstat`, `sar`, and `mpstat` to diagnose CPU and memory related performance issues.
Diagnose Performance Issues
Understanding system performance is key to troubleshooting slow applications or an unresponsive server. CPU and memory are often the first resources to check.
In this lesson, we'll explore powerful command-line tools to monitor and diagnose issues related to your system's CPU and memory usage.
Meet `vmstat`
The vmstat (virtual memory statistics) command provides a quick, real-time snapshot of your system's activity. It reports on processes, memory, paging, block I/O, traps, and CPU activity.
It's excellent for observing current system behavior and identifying immediate bottlenecks.
