Datadog Agent Manager is an open-source project that was designed to facilitate a complex system for monitoring and optimizing the activity of an organization's servers, cloud applications, metrics, internal tools, and people's activity.

The service enables access to a wide variety of management features and interactions, and offers full API access to enhance existing apps integrations, write custom code for capturing metrics, tag servers and queries in your command-line, or generate and upload your dashboard (in a JSON format).

The tool allows monitoring plenty of different systems and services. Based on your existing stack, the service allows installing a custom Datadog agent for MacOS, Windows, Debian, Ubuntu, Amazon Linux, Fedora, SUSE, Docker, Kubernetes, OpenShift, including many others.

With Datadog Agent Manager, one can opt for individual services exclusively; for example, you can only choose to monitor your network's devices and traffic for clarity, security, troubleshooting, and real-time error prevention. You can conduct real user monitoring. This enables collecting data from your apps' crashes and gathering error reports for optimizing performance.

Some other nice extras offered by the Datadog service are its capacity to offer sophisticated synthetic monitoring features. These consist of options to track a website's availability (uptime, latency, general overall performance, SLAs and SLOs, etc), plus mechanisms to observe, understand, and optimize the user journey — web-recording of tests' sessions, screenshots and frontend error displays, real-time alerting, and sorting/filtering with tags.

Datadog Agent Manager is a complex tool, and the service itself, is an extensive, complete solution for many of (if not, all) your problems.
