The Sunburst GPU chart updates every second to show a real-time view of the share of GPU resources being consumed by namespaces operating on the Nautilus hyperconverged Kubernetes cluster. The Nautilus cluster tightly couples distributes storage, GPU, and CPU resources to share among the participating research organizations. The Sunburst Process chart provides an up to the second view of the cluster-wide share of CPU resources used by each namespace. The Sunburst DNS chart shows a real-time...

Linux as a network operating system describes the benefits of using standard Linux as a network operating system for hardware switches. A key benefit is that the behavior of the physical network can be efficiently emulated using standard Linux virtual machines and/or containers. In this article, CONTAINERlab will be used to create a simple testbed that can be used to develop a real-time DDoS mitigation controller. This solution is highly scaleable. Each hardware switch can monitor and filter...

The sFlow-RT real-time analytics platform receives a continuous telemetry stream from sFlow Agents embedded in network devices, hosts and applications and converts the raw measurements into actionable metrics, accessible through open APIs, see Writing Applications . Application development is greatly simplified if you can emulate the infrastructure you want to monitor on your development machine. Mininet flow analytics , Mininet dashboard , and Mininet weathermap describe how to use the ope...
