Detailed Description

Container monitoring plugin aggregating Docker, Kubernetes, and cgroup collectors.

This plugin provides container-specific metrics collection for containerized deployments. For bare-metal deployments, this plugin should not be loaded to reduce binary size and avoid unnecessary collection overhead.

Metrics provided:

• Docker: container CPU/memory/network/I/O, running containers count
• Kubernetes: pod count, restarts, deployment replicas, node resources
• cgroup: CPU time, memory usage/limits, I/O bytes
