Hi Experts,
I am looking for opensource Network and server monitoring tool for RRAS Windows 2008. I want to monitor the traffic coming from internet to my specific client and servers. I also want an email alert in case any server goes down or disruption of network connectivity. 

Which one is the best freeware network monitoring tool?

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).
