  • Method and apparatus for drilling to measurement data from commonly displayed heterogeneous measurement sources
    Patent number: 6826507
    Abstract: A network monitoring and/or troubleshooting system to collect heterogeneous scalar measurement data over a network from a plurality of devices connected to the network and normalize the collected heterogeneous scalar measurement data based on a mathematical transform of collected scalar measurement data into a common mathematical space. When the transformed scalar measurement data is displayed in graphical representations, underlying data of the graphical representation can be drilled into, with context, to display additional heterogeneous scalar measurement data, scalar measurement data from data collectors, and measurement data stored in network devices generating the heterogeneous scalar measurement data.
    Type: Grant
