What software is this in my menubar? Right beside the Alfred icon, there's a small up and down arrow indicating bandwidth upload and download speeds.

I remember downloading and installing something for this, and now I can't remember the name of it. I'm trying to enter the settings for it and also add in the RAM tickers.

Any ideas on what software causes the up/down icons next to the black hat icon?
That program is MenuMeters, available at http://www.ragingmenace.com/
