Metricbeat, a lightweight shipper for host and service metrics introduced in the Beats 5.0 release, replaces Topbeat and expands its capabilities by incorporating control group (cgroup) metrics from the Linux kernel. Cgroups, used for resource allocation and usage metering in processes, enable Metricbeat to collect detailed metrics from containerized environments without relying on container tool APIs, though this approach limits access to container-specific metadata. By enabling cgroup metrics in Metricbeat's configuration file, users can gather data on CPU, memory, and block I/O usage, with forthcoming network metrics, offering a process-centric view that can equate to a container-centric perspective when running single processes per container. This feature, initially released as experimental, may undergo enhancements based on user feedback, and while it provides critical resource usage data, users can engage with the Beats engineering team for further questions or feature requests through Elastic forums.
