Manual Monitoring
Manual monitoring is a process where developers or operations teams actively observe and check the performance, health, and behavior of systems, applications, or infrastructure without relying on automated tools. It involves tasks like reviewing logs, checking dashboards, and performing ad-hoc tests to detect issues. This approach is often used in smaller-scale or less complex environments where automation may not be feasible or cost-effective.
Developers should learn manual monitoring for scenarios where automated systems are unavailable, during initial development phases to understand system behavior, or in legacy environments with limited tooling. It's crucial for troubleshooting immediate issues, gaining hands-on insights into system performance, and as a fallback when automated monitoring fails, ensuring operational resilience and quick problem resolution.
