Network TroubleShooter Is Software-Only
Observer 4.0, from Network Instruments, is a software-only, Windows 95/NT-based protocol analyzer and network troubleshooting tool available for Microsoft, UNIX, Novell, Apple, DEC and IBM networks. Priced at $695, it lets administrators monitor bandwidth utilization; collect statistics in both list and chart form by user, packet size, or protocol; capture, view, and decode LAN traffic; and set triggers and alarms to pinpoint critical problems. Douglas Smith, Network Instruments president, points out that "Observer now provides the same level of functionality and speed that hardware-based analyzers have traditionally provided -- at thousands of dollars less."
This new version features a Web Observer mode for tracking local Web server status; network error reporting; auto-discover of IP addresses, NetWare login names and NetBIOS names; and many new functions.
