Network Instruments Observer 9.x

Network Instruments Observer 9.x ... cost-effective, software-only, Microsoft Windows-based network monitor and LAN troubleshooting tool. Observer can monitor single-segment LANs and with the addition of Probes, Observer can be upgraded into a full distributed product for monitoring multi-segment LANs and WANs. Observer offers both real-time monitoring and troubleshooting, as well as a complete trending and base-lining collection system to view historical data collected for days, weeks, months or even years. With Observer, a network administrator can view his or her LAN more clearly, see network traffic in real time, and with this new information, make network decisions based on facts instead of guesswork.
