I've found lots of similar questions, but nothing that's exactly right.
I'm trying to figure out what's making one server run slower than another. I'm hoping for something that would say something like what resources are being used the most (I/O, ram, cpu, chickens) and what processes are using those resources in significant amounts.
I don't just want to start throwing solutions at it to see what will stick. I want metrics of some kind. I don't want to sit there with top, iotop, nettop & chickentop open, scribbling in a notebook.
