I'm looking for some kind of tool that can generate a report on network availability. For instance; this utility would run on a server and perform tests to other hosts and routers across the network. The usual Network Monitoring Tool tests like ping, port response, etc but also things like throughput between monitoring host and destination, packet-loss and a total percentage of availability for that host. Obviously the availability "number" would be dynamic based on the results of the tests and how the user configures the impact of those tests against the available percentage. Has anyone seen anything like this in one nice little package? What I'm going to do is give the head honchos a URL where all they have to do is click on a portion of our network and read off the uptime percentage. Thx!
