Abstract: Techniques for performing traffic outage detection in the Internet are disclosed. In some embodiments, a system, process, and/or computer program product for traffic outage detection in the Internet includes deploying a plurality of agents and a plurality of tests to be executed by the deployed agents; collecting path trace data from the plurality of agents to identify one or more terminal events; and detecting a network outage based on the one or more terminal events.

Abstract: In one embodiment, a device obtains test results for tests targeted at a web application, the tests performed by a plurality of agents. The device maps a portion of the test results to a component of the web application based on identifying information within the portion of the test results. The device makes, based on the portion of the test results that are mapped to the component of the web application, a determination that the component of the web application is experiencing an outage. In one embodiment, the device causes, based on the determination that the component of the web application is experiencing the outage, a mitigation action for the outage.

Abstract: In one embodiment, a method comprises: obtaining, by a process, path trace data collected by a plurality of performance monitoring agents across a computer network; obtaining, by the process, one or more catalogs having application-based correlation information for the path trace data; generating, by the process, network mapping directed graphs by correlating the path trace data using the one or more catalogs, the network mapping directed graphs logically comprising nodes categorized at a plurality of levels of aggregation and edges connecting the nodes; associating, by the process, test-based performance data with the edges of the network mapping directed graphs; and providing, by the process, at least one Sankey diagram based on the network mapping directed graphs and test-based performance data associated with their edges for selectable display by a user interface.
