About LiveWire Virtual
Congratulations on your purchase of LiveWire Virtual™! LiveWire Virtual is a virtual version of the LiveWire hardware network appliance. LiveWire Virtual uniquely combines flow-based reporting using deep packet inspection (DPI) with high-speed, packet capture and storage. LiveWire Virtual is designed to work with LiveAction’s LiveNX, an innovative network performance visualization and analytics solution. LiveWire Virtual provides visibility in areas where flow-based data is typically not readily available, and is optimized for data center visibility.
Because LiveWire Virtual starts with packet data, it is able to provide a unique, and extended, set of flow-based monitoring data called LiveFlow. LiveFlow is extended IPFIX data and is exported to LiveNX, where the complete network topology is visualized. LiveNX stores monitoring data for both long-term reporting and real-time alerting. Regardless of the depth of LiveFlow data, there are inevitably times when packets are required for detailed, root-cause analysis. Since LiveWire Virtual is also storing all of the packets while simultaneously generating LiveFlow, issues identified on real-time LiveNX dashboards can easily be analyzed in detail, down to the packet level, by simply identifying an alert or a flow that needs further investigation. See Chapter 3, Exporting Data to LiveNX for the additional tasks you must perform in order to export LiveFlow data from LiveWire Virtual to LiveNX. Please also refer to the LiveNX documentation for more information on using the LiveFlow data exported to LiveNX.
The Capture Engine software on LiveWire Virtual works in conjunction with Omnipeek, a separate software program required for the monitoring and analysis of the packets captured remotely by LiveWire Virtual. For detailed instructions on how to view and analyze remote captures from within the Omnipeek console, please see the Omnipeek User Guide or Omnipeek online help. For more information on the Capture Engine software, please see Chapter 4, Capture Engines.
