Chapter 1. Overview<br />
Analysis <strong>and</strong> visualization of network traffic is important for optimizing <strong>and</strong> protecting the operation<br />
of networked IT infrastructures. <strong>Tivoli</strong> Netcool Performance Flow Analyzer is designed to gain tight<br />
control over end-to-end resource usage for hosts, servers, services, applications, protocols, domains,<br />
autonomous systems, quality-of-service classes, interfaces, <strong>and</strong> user-defined combinations of these<br />
aspect components.<br />
The system operates passively by generating detailed network traffic reports from flow-information<br />
streams such as NetFlow, IPFIX, jFlow, cflowd <strong>and</strong> NetStream. Traffic views <strong>and</strong> reports provide<br />
detailed asset usage information that ranges from seconds to years. The system supports network<br />
planning as well as network operation — for instance, through identification of network congestion<br />
causes. The system can also be used to estimate traffic impact with server consolidation <strong>and</strong> new<br />
application roll-outs or pilots.<br />
