Baseliners

Baselining, the practice of keeping long-term statistics, is a very important part of problem determination when, as they say, “The network is slow!” After all, if you don’t have a sense of how things typically are, how can you tell when something is out of range? Long-term, service-level record keeping is also a way to know—and a way to show your boss—that everything is operating efficiently and is working properly.

The point of baselining is that if you don’t know what things look like when times are good, you’ll have no idea what you’re looking for when things go bad. Accordingly, you really want to expend a little effort and create a picture of what your network infrastructure looks like when things are running pretty well.
