IT organizations can no longer manage networks in isolation from the applications they support. Traditionally, IT staff built their network management practices around infrastructure availability and fault management. Today, most networks are available more than 99 percent of the time and increasing user expectations for fast, trouble-free networked applications requires a shift from a device-centric to a performance-centric focus. For Performance First to be viable, a rich set of performance metrics must be gathered and analyzed because today's complex networks present multi-dimensional challenges. Real-time metrics are required for day-to-day operational visibility into application delivery while historical data and trends are needed to support infrastructure investment decisions.
