Internal Monitoring
Internal monitoring is the practice of tracking and analyzing the performance, health, and behavior of software systems from within the application or infrastructure itself. It involves collecting metrics, logs, and traces to detect issues, optimize performance, and ensure reliability in production environments. This approach provides deep visibility into system internals, enabling proactive management and troubleshooting.
Developers should implement internal monitoring to maintain system reliability, quickly diagnose production issues, and meet service-level objectives (SLOs). It is essential for distributed systems, microservices architectures, and cloud-native applications where traditional external monitoring may miss internal failures or performance degradation. Use cases include tracking application response times, error rates, resource utilization, and business metrics to support operational excellence.
