Container monitoring is a practice that collects metrics and tracks the health of containerized applications and microservices architectures to ensure security, performance, and availability. It's a subset of container observability and helps DevOps teams reduce mean time to recovery (MTTR) of performance issues, meet critical KPIs, and troubleshoot root cause analysis. However, traditional monitoring tools often struggle with distributed microservices environments, making cloud-native monitoring tools necessary. A suitable container monitoring tool should provide an overview of the application and infrastructure components, correlate logs and system events, and visualize the topology of the container ecosystem. Advanced features like automated resource utilization recommendations are also important. Container scanning can help DevSecOps teams proactively find new vulnerabilities in custom code, open-source dependencies, containers, and Dockerfiles. A developer-first container security approach complements container monitoring by empowering developers to fix security issues through direct guidance and automating fixes through pull requests.
