You know that servers have log files and performance measuring tools and that
traditional network devices have LEDs that blink when a port does something.
You may have tools that tell you how busy an interface is, but mostly a
network device is a black box. Network Flow Analysis opens that black box,
demonstrating how to use industry-standard software and your existing hardware
to assess, analyze, and debug your network.Unlike packet sniffers that require
you to reproduce network problems in order to analyze them, flow analysis lets
you turn back time as you analyze your network. You'll learn how to use open
source software to build a flow-based network awareness system and how to use
network analysis and auditing to address problems and improve network
reliability. You'll also learn how to use a flow analysis system; collect flow
records; view, filter, and report flows; present flow records graphically; and
use flow records to proactively improve your network. Network Flow Analysis
will show you how –Identify network, server, router, and firewall problems
before they become critical–Find defective and misconfigured software–Quickly
find virus-spewing machines, even if they’re on a different
continent–Determine whether your problem stems from the network or a
server–Automatically graph the most useful dataAnd much more. Stop asking your
users to reproduce problems. Network Flow Analysis gives you the tools and
real-world examples you need to effectively analyze your network flow data.
Now you can determine what the network problem is long before your customers
report it, and you can make that silly phone stop ringing.
