How to Install Datadog Agent on Docker Container?
In the dynamic landscape of containerized applications, monitoring and managing your Docker containers efficiently is crucial. Datadog, a popular monitoring and analytics platform, provides an agent that allows you to gain insights into the performance of your containers. In this guide, we will walk through the step-by-step process of installing the Datadog Agent on a Docker container, ensuring you can keep a close eye on your application's health.
