I attended the EBCUG meeting tonight where NetScout gave a presentation on their product. I will be using this product pretty soon as our tool for performance and reporting of our network. It does some pretty cool reporting that folks should definitely check out. If you are trying to do regular reporting on the performance of your network this is pretty much the Cadillac of solutions. If your shop has been running MRTG or Cricket for a few years but are itching to get more out of your tools this is the way to go.
Now I just need to find the time for the training class. Go figure.
