摘要： In one embodiment, a method comprises: establishing, from an agent hub device, a tunnel to a remote vantage point device; generating, by the agent hub device, test traffic to appear as though the test traffic originates from the remote vantage point device; encapsulating, by the agent hub device, the test traffic into the tunnel to the remote vantage point device to cause the remote vantage point device to decapsulate the test traffic and send the test traffic as though the test traffic originated from the remote vantage point device; receiving, at the agent hub device, one or more returned test responses in response to the test traffic; and producing, by the agent hub device, test results based on the one or more returned test responses.

摘要： A method and system are described. The method and system include determining a grouping characteristic for a plurality of nodes and a corresponding plurality of links. The nodes and the links correspond to components of a network and are associated with network performance information. The grouping characteristic includes at least one of partitionability into pages and a hop distance. The method and system also include generating a graphical visualization based on the grouping characteristic, the nodes and the links.

摘要： 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.
