A perspective on open source network monitoring tools...
…by Grig Gheorghiu over on the Agile Testing blog: The sad state of open source monitoring tools.
I wish there was a standard nomenclature for this stuff, as well as a standard way for these tools to inter-operate. As it is, you have to learn each tool and train your brain to ignore all the weirdness that it encounters.
One of the problems with I.T. is the absence of a standard terminology. It would make things a lot easier if everybody used a standard set of terminology. Kinda hard to see how this can be imposed though. I guess over time a standard terminology will just evolve after the industry has matured a little more.
