In the previous article in this series—The Everything Guide to Data Collection in DevSecOps—we discussed the importance of data collection. In this article, we'll explore the role of monitoring in observability, especially as it relates to security, performance, and reliability. Monitoring is essential for detecting issues and outliers as they happen in production and allows DevSecOps teams to identify and address issues before they cause serious damage. Monitoring performance degradations or suspicious activity can result in alerts and automatic responses to isolate potential problems or attacks.
In this article, we’ll look at monitoring in detail, provide several use cases and best practices, and discuss how monitoring can specifically improve security, performance, and reliability through observability.
