  • Patent number: 10284444
    Abstract: A method for visual representation of end user response time (EURT) in a multi-tiered network application is provided. Search criteria for searching a repository of client statistics records is received. The search criteria specifies identification information pertaining to a user of a multi-tiered network application experiencing application performance problems and a time period associated with the application performance problems. The identification information identifies an IP address of user's computing device. A plurality of client statistics records matching the search criteria is retrieved from the repository. The retrieved plurality of client statistics records is sorted based on measurements of performance parameters. A graph representing relevant topology hierarchy of the multi-tiered network application is presented to a user based on the sorted client statistics records. The graph visually identifies connections between nodes of the multi-tiered application.

    Abstract: A storage system includes network monitoring device having NIC coupled to network and configured to capture raw data packets. The system further includes 4 data repositories. A first repository stores captured packets. A second repository stores captured packets' metadata. A third repository stores captured packets' and metadata's timestamp indexed data. A fourth repository stores captured packets' data flow. The storage system further includes a storage engine coupled to the repositories. The storage engine receives packet search criteria specifying at least a first time range. Data flow information associated with the search criteria is retrieved from the fourth repository. The retrieved data flow information is associated with a second, narrower, time range. Metadata information associated with the second time range is retrieved from the second repository using corresponding timestamp indexed data.
