The application can look at performance over the public network to create a customer-side view so administrators can ensure that communications in individual regions aren't faltering while the rest of the network looks healthy. recently introduced the nGenius Application Service Level Manager to track response times of individual links on the user's Web site and determine which servers are experiencing slowdowns. Similarly, Westford, Mass.-based NetScout Systems Inc. Intended for companies that conduct business over the Internet, the application can generate reports about protocol and bandwidth usage when traffic over the public network stalls. If necessary, they can trigger alarms when traffic loads or performance delays surpass limits set by network administrators.Īmong today's wide-ranging network analysis products is the Sniffer Total Network Visibility Suite from the Sniffer Technologies unit of Santa Clara, Calif.-based Network Associates. Rmon-savvy sniffers can take constant readings on the health of network components and compare those readings against historical trends. Modern sniffers typically incorporate remote monitoring standards (Rmon and Rmon 2), which define a standard way for systems to automatically collect key performance data points such as resource utilization. If application-level analysis fails to provide a solution, sniffers can drill into low-level activities. Rather than merely identifying low-level characteristics such as packet source and destination, current sniffers can decode data from all seven layers of the Open System Interconnection network stack and can often recommend fixes for problems. These bundles give administrators a centralized view of networks to monitor high-level activity, such as which applications are running, which users are logged on to the network and who is the source of unusually large files or high volumes of traffic.

The second is part of a larger package of network-monitoring hardware and software for helping organizations keep tabs on their LANs, WANs and Web services.

The first is a stand-alone product incorporated into a portable computer that consultants can carry to customer sites and plug into the network to gather diagnostic data. Today, sniffers exist in two broad varieties.
