Open source end-to-end network diagnostic tool?


I am looking for an end-to-end network diagnostic tool. If one matching my needs does not exist, I may begin creating one.

Basically what I think this should look like is a client-server model, where I can deploy a client program on each machine in a network path. There should be a central GUI on the server with a visual map, perhaps in a web interface, displaying the network path. It will use pcap information on the clients to keep track of packets and determine if/when they are being dropped along the way. It should also be able to use, for example, syslogs and iptables rule matches for each machine in the path to determine why the packet was dropped (i.e. dropped due to routing error, dropped due to firewall rule, etc.) and then include this in the report.

Anyone heard of something similar to or better than this solution?

I like Nagios. It should be easily extensible with your own plugins if it doesn't already do something you need.


diagnostics, iptables, networking, pcap file, routing
