The text discusses the integration of Docker and Datadog, highlighting how Docker's philosophy of isolating applications with containers can benefit monitoring. The traditional Datadog setup involves installing the Agent on a server, while the Docker-ized approach uses containers to isolate the Agent from the rest of the system. This allows for efficient monitoring of containerized applications without requiring a full virtualization setup. The integration enables users to monitor custom metrics and send data to Datadog, with options for alerting and visualizing Docker metrics through a free trial.
