PS-Dash –Analysis, Monitoring and Visualization of Network Measurements

Network performance and stability is a crucial part for an international scientific collaboration with shared resources. Therefore, frameworks such as perfSONAR use various tools to track important network measures between nodes and gather extensive information about the underlying network. Given the amount of data collected (an average of 18 million measurements daily) and the level of expertise required to understand a specific issue, the need for a new application has emerged. PS-Dash provides a general overview of the network; ranks Sites based on their metrics; and highlights some major problems on the grid. It allows site admins and other experts to review the state of the scientific network infrastructure and presents references to external resources for in-depth analysis.
