The Benefits of Performance Management

• Contain Costs
• We avoided a 30,000 per month upgrade for 10
  months because NetScout helped us discover a
  mistake in a routing table.
• Ensure High Quality Services
• If we didnt have the Real Time Monitor, we
  probably would have been down for four or five
  hours, as opposed to one hour. So, reducing a
  four-hour down time to a one-hour down time is
  worth 390,000 to us.
• Improve Operational Efficiencies
• I had received a complaint about the network
  being slow, but it was a couple of days after the
  fact. And so, I went back with the Traffic
  Monitor, looked at the link during that time, and
  found out that somebody had scheduled a backup of
  a server at that time. I was able to figure out
  what the problem was without having to wait for
  it to happen again. .
