Kubernetes Integrated Heapster Monitoring

Heapster is a container cluster monitoring and performance analysis tool that naturally supports kubernetes and CoreOS.
Kubernetes has a well-known surveillance agent-cadvisor. The cadvisor is run on each kubernetes node, and it collects monitoring data (cpu,memory,filesystem,network,uptime) for both native and container.
In the newer version, K8S has integrated the Cadvisor functionality into the Kubelet component. Each node can be accessed directly from the Web.
