Datadog has introduced a series of feature enhancements aimed at improving observability by expanding its integrations and data collection capabilities. This first post in a series highlights the addition of application performance monitoring (APM), which is now included with the Datadog Agent, allowing for easy deployment and open-source customization. APM supports multiple programming languages and web frameworks, enabling users to trace application performance and issues across service boundaries. Datadog has also expanded its integrations with major cloud providers like AWS, Google Cloud Platform, and Microsoft Azure, alongside other tools and services, to enhance visibility and monitoring. The Autodiscovery feature simplifies tracking and monitoring of containerized services, crucial in dynamic environments where containers frequently change. These advancements aim to help users efficiently collect and analyze data to quickly identify and resolve performance issues, setting the stage for further enhancements in alerting and algorithmic monitoring discussed in subsequent posts.
