For a network engineer, it sometimes feels impossible to avoid traceroute. Tim Miller thinks it can be a valuable tool to see where traffic is getting dropped, but it’s not without its issues. He’s highlighted some other solutions in previous posts, but the one he’s looking at today is SolarWinds. Their NetPath tool has gone from a lab toy to an official feature of their Network Performance Monitor solution in a little under a year. Tim finds it a really impressive tool. Even though it requires Windows-based polling appliances in a network, a Linux guy like Tim can still be tempted. It gives historical information layer on top of what you would find with a traceroute, and adds multipathing. Overall, Tim sees this as a very practical tool to help disentangle issues in increasingly complex networks.
