Monitor Harbor container registry with Datadog

Harbor is an open-source registry for container images and Helm charts developed by VMware and hosted by the CNCF. It offers several advantages over Docker's default registry, such as role-based access control, security scanning, and resource replication. Datadog has introduced a new integration for Harbor that allows users to monitor its health and performance alongside their containerized applications and infrastructure. The integration includes tracking disk usage, notifications if Harbor goes down, automatic tracking of health checks, and log analysis for faster troubleshooting. This helps ensure uptime for self-hosted registries and the services that depend on them.
