Monitoring and Observability for Modern Apps
As systems are split into many services, it becomes harder to understand what is happening just by looking at a single server. Monitoring and observability tools collect metrics, logs and traces to give teams a clear picture of system health.
Basic monitoring answers the question, is the system up. Observability goes further and helps you answer, why is it slow or failing, using data that is already being collected without adding new code for each incident.
Starting with simple dashboards and alerts for key metrics such as error rate, latency and resource usage already gives great value and can be expanded over time.
