What is Performance Monitoring?
Performance monitoring involves tracking and analyzing the resource usage and health of a computer system in real-time. By using command-line tools like top, htop, vmstat, and iostat, you can observe how CPU, memory, disk I/O, and network bandwidth are being consumed by various processes. This practice helps in identifying bottlenecks, troubleshooting unexpected spikes in resource demand, and ensuring that applications run efficiently under different workloads.
