Network Inspector is a powerful network monitoring, troubleshooting
and data analysis solution. Designed for switched Ethernet LANs,
Network Inspector (NI) actively monitors and diagnoses problems in
TCP/IP, IPX , and NetBIOS environments. It rapidly identifies whether
the problems lie on the server, client, switch, router, or printer
through its quick discovery process, and provides an extensive suite
of reports identifying all devices in the LAN, the services they
provide and an array of tools and reports for data analysis. Network
Inspector will automatically notify you via page or email, when
something goes wrong even on remote sites when used in combination
with the OptiView Network Analyzer. Whether you need reports on IP
and IPX or detailed infrastructure diagrams, Network Inspector makes
network documentation quick and easy. Network Inspectors seamless
integration with other Fluke Networks tools such as the OptiView
Network Analyzer, the OneTouch Series II Network Assistant, the
Enterprise LANMeter and the 68x Traffic Analyzer, provides you with
even more troubleshooting and discovery capabilities for remote
locations.
