# Containers

The Containers table provides real-time visibility into all containers across your environment monitored by Datadog. Each row represents a container and includes metadata about resource limits (CPU, memory, threads), lifecycle timestamps (creation and start times), orchestration platform details, container images, and associated tags. This table enables you to monitor container health and performance, track resource allocation across your containerized workloads, correlate containers with their host infrastructure, and gain insights into your Docker, Kubernetes, ECS, and other container orchestration environments. The Datadog Agent automatically discovers and monitors all containers on each host.
