Abstract: A computing system comprising storage media and processing circuitry may perform the techniques. The processing circuitry may aggregate a plurality of performance metrics for a plurality of network entities of a network system into a metric indicative of a health of the plurality of network entities. The processing circuitry may, based at least in part on a determination that the aggregated metric indicative of the health of the plurality of network entities does not satisfy a threshold, identify one or more network entities of the plurality of network entities for which the corresponding performance metrics of the plurality of performance metrics contributed to the aggregated metric not satisfying the threshold. The processing circuitry may output a cause of fault associated with the identified one or more network entities.

Abstract: In general, this disclosure describes techniques that enable a network system to perform application-aware active measurement for monitoring network health. The network system includes memory that stores a topology graph for a network. The network system includes processing circuitry that may receive an identifier associated with an application utilizing the network for communications, and determine, based on the topology graph and the identifier, a subgraph of the topology graph based on a location, in the topology graph, of a node representing a compute node that is a host of the application. The processing circuitry may next determine, based on the subgraph, a probe module to measure performance metrics associated with the application, and for the probe module, generate configuration data corresponding to the probe module. The processing circuitry may output, to the probe module, the configuration data.
