## Abstract

An example control plane that is executed on one or more processors in a distributed computing system is configured to receive an indication of a node to be onboarded into the distributed computing system, wherein the node comprises one of a compute node or a network device node, to discover one or more compute resources or network device resources that are associated with the node, and to assign, based on the discovery, the node to a collector that is executed in the distributed computing system, wherein the collector is configured to collect real-time telemetry data for the node during operation of the node. The control plane is further configured to receive, from the collector, the real-time telemetry data for the node that is collected by the collector, and to output, for display, a visual representation of the real-time telemetry data for the node.
