I have a few networks that report loss of internet at random times (despite being on a UPS) and I am looking for a way to measure network accessibility with an old mac mini g4. Ideally, I'd like to be able to place the mini on the companies network and have it immediately start a schedule of tests. We use PathView on other sites, but at $1200 it's a bit pricey. Anyone know of a mac-based (or pc-based for that matter) program that can measure performance characteristics such as jitter, latency and available bandwidth from any location to any IP-addressable target worldwide. I would then log into the device to check the logs OR have them sent to my office for archiving and analysis. Any ready-to-go programs that do this?
