Abstract: An example method includes (a) generating a request to obtain log data descriptive of operation of an autonomous vehicle control system in a subject scenario, the log data indexed by an indexing parameter; (b) submitting the request to a log repository service, the log repository service configured to receive the request and serve, responsive to the request, log metadata; (c) loading, based on the log metadata and an index value of the indexing parameter, a log data sketch associated with the index value; and (d) loading, based on the log metadata and the index value, and responsive to an inspection indicator, detailed log data associated with the index value.

Abstract: Disclosed are methods and apparatus for implementing in an electronic device that includes a processor and memory. Virtual resources, which are associated with an execution of a user's applications in a cloud resource configuration including virtual machines, network services and storage, are identified. A first topology map of the virtual resources, including a plurality of nodes, is generated. The first topology map, including the nodes, is output. A vector, which is associated with each node, said vector including one or more features associated with each node, is generated. Based upon the vectors, a distribution of the plurality of nodes within two or more groups is determined. A second topology map, including each of the node groups in one of a collapsed format, wherein only a identifier of the node group is output or an expanded format, wherein a portion of the plurality of nodes the node group are output, is output.

Abstract: Once a potential bottleneck is identified, the system provides a methodology for locating the bottleneck. The methodology involves checking in order each of the application, transport and network layers of a sender and receiver nodes for performance problems. Conditions are defined for each of the layers at the sender and receiver nodes that are indicative of a particular type of bottleneck. When the conditions are met in any one of the layers, the system can be configured to stop the checking process and output a message indicating the presence of a bottleneck in the layer and its location. In addition, the system can be configured to generate and output a remedial action for eliminating the bottleneck. The system can be configured to perform the action automatically or after receiving a confirmation from the user.
