Systemd is an initialization program that manages processes on Linux systems, creating a dependency tree of system components and initializing them only when needed. With the integration with Datadog, comprehensive visibility into system management within Linux deployments is provided, allowing users to monitor the health and performance of both systemd and its managed components. The integration offers detailed metrics for unit status, troubleshoot process initialization, and out-of-the-box dashboards for per-unit metrics across infrastructure. It also includes service checks to detect unit failures, resource consumption, and provides alerts and notifications when issues arise, enabling users to diagnose issues with process management more easily.
