System Metrics
System metrics are quantitative measurements that track the performance, health, and resource utilization of computer systems, including hardware, software, and networks. They provide insights into CPU usage, memory consumption, disk I/O, network traffic, and application-specific performance indicators. These metrics are essential for monitoring, troubleshooting, and optimizing system operations in real-time or historical analysis.
Developers should learn and use system metrics to ensure application reliability, identify performance bottlenecks, and optimize resource allocation in production environments. This is critical for DevOps, SRE roles, and any developer working on scalable systems, as it enables proactive monitoring, capacity planning, and debugging of issues like memory leaks or high latency.
