Monitoring and alerting play a vital role in the DevOps practice, providing visibility into the performance and health of applications and infrastructure. Monitoring involves the collection and analysis of various metrics, such as CPU usage, response time, and memory utilization. This data helps identify performance bottlenecks, detect anomalies, and track the overall system health. Alerting, on the other hand, enables teams to be notified when specific events or thresholds are met. By setting up alerts, teams can proactively take action to resolve issues before they impact end-users. Additionally, monitoring and alerting facilitate continuous improvement. By analyzing the collected data, teams can identify areas for optimization, make informed decisions, and enhance the overall performance and reliability of their systems.
