METHODS AND SYSTEMS FOR ESTIMATING AND ANALYZING FLOW ACTIVITY AND PATH PERFORMANCE DATA IN CLOUD OR DISTRIBUTED SYSTEMS

摘要

Virtual resources associated with an execution of a user's applications in a cloud or distributed resource configuration including virtual or physical machines, network services and storage are identified. A source and destination virtual machine, utilized by the user's applications, are determined, and at least one source or destination virtual machine belongs to the identified virtual resources. Measurement software for a virtual machine is downloaded. The measurement software acquires data for connections established in a transport layer for communicating between the source and destination virtual machine. Data acquired from the measurement software is received at a first time, and the data includes measurements of variables for the data communications via the connections. Based upon the measurements, metrics that characterize the data communications at a first time are generated. Measurements made at an additional number of times are also received. Based upon the measurements, metrics are generated as a function of time.
