People who spend a lot of time working on networked computers end up spending a lot of time trying to work out what’s wrong with their network.
Path Analyzer Pro Premier 2.6, from Vostrom, can help you find the trouble spots. Mac OS X ships with Network Utility, which does a perfectly reasonable job of running traceroute, a Unix utility that shows every hop – each stop your data makes between computers on your network and across the internet – and how long it takes. Given that Network Utility (located in /Applications/Utilities/) comes free with your OS, do you need anything more? If you want more detailed information, the answer is yes. While Network Utility is fine for light research, Path Analyzer Pro does considerably more.
Path Analyzer Pro can show you your network data in a variety of ways: as a standard traceroute, a chart showing latency (the time between each hop), a summary of the route taken, a log of every command sent, as statistics, and even as a geographical map showing the route your request took on its way to the server. You can trace IP addresses, URLs, and even email addresses. The program also allows you to customise your traces in ways that only serious networking gurus might imagine. For example, along with a single trace, you can do continuous or timed traces, which lets you see more than just Network Utility’s single snapshot. You can also choose which ports and protocols you want to use for your traces.
For a program that has so many options, there’s a dismaying lack of documentation on what many of these options do. The program does not come with a manual. Clicking on Help in the application brings up a web page with links to a few pages: an FAQ, installation instructions, a video demo, and a feature overview.
The weakest part of Path Analyzer Pro is its mapping. A traceroute that starts and ends in Northern California can find itself displayed as visiting Massachusetts or New Jersey, a path contradicted by the geographically tagged names of the routers listed in the trace.
