I have a long list of network tools to wade through. Here’s another one, that I like very much: netwatch.
I keep notes on each application as I skim through them, and for netwatch my notes say, “very nice, multicolor, lots of options, good clean fun.”
Which is probably a fair assessment — a very nice arrangement, with left and right panels. Good use of color, with offset red and blue. Plenty of options, skipping through the available data with the left and right keys, or panels with the tab key.
Maybe more than any other category, network monitors are going to be a matter of preference. You’ll have to try each one a little, and decide what works best for you.
At least you have plenty to pick from … 🙄
