Abstract: In one embodiment, a method includes identifying a problematic event between a first interest point and a second interest point of a network and activating, in response to identifying the problematic event between the first interest point and the second interest point, a first endpoint associated with the first interest point and a second endpoint associated with the second interest point. The method also includes receiving, from the first endpoint and the second endpoint, telemetry data associated with a problematic path between the first interest point and the second interest point. The method further includes determining the problematic path between the first interest point and the second interest point using the telemetry data received from the first endpoint and the second endpoint.

Abstract: This disclosure describes techniques for enabling distributed path computation and centralized path enforcement in a computer network used to implement a software application. In some cases, the disclosed techniques include using a central controller that initializes and coordinates monitoring agents deployed to network regions. The monitoring agents may collect monitoring data associated with application segments in their respective regions and share this data with each other. Using the aggregated data, the agents can compute optimal paths between application segment pairs spanning multiple regions. The optimal inter-region paths may be sent to the controller, which can program the paths into the routing application programming interfaces (APIs) of the various network environments like public cloud and on-premises networks.

Abstract: This disclosure describes dynamically monitoring the flow of traffic along a path that can include points across different cloud service provider networks/regions and/or different private networks. Flow monitoring may be started in response to different triggering events. For instance, flow monitoring of network traffic along one or more network paths may be started in response to performance metrics associate with an application within the multi-cloud environment, current/projected network conditions associated with one or more networks within the multi-cloud environment, and the like. In other examples, a user may specify when to perform flow monitoring for one or more network paths.
