Apache Mesos is a data center abstraction layer that simplifies running distributed systems at scale, but it can be complex to deploy and requires finding compatible solutions for various tasks. To simplify the process, DC/OS (Datacenter Operating System) is introduced as a full-fledged operating system for Mesos clusters, bundled with technologies to handle service discovery, load balancing, monitoring, and more. Datadog, a popular choice for monitoring Mesos clusters, can be easily deployed across Mesos clusters using DC/OS, and out-of-the-box integrations are available for Mesos, Docker, and related services. The installation process involves installing the Datadog package on agent nodes first, followed by leader nodes, where the Datadog Agent is installed as a standalone Docker container. Once installed, users can monitor all cluster metrics, including those from Mesos, Docker, and other services, using pre-built dashboards and custom integrations. Additionally, Autodiscovery enables automatic detection of running services on each node, simplifying configuration and setup.
