I have only visual feedback, on the overview page you can maybe set the '%' in a lower size font, it takes almost the space of 2 digits, or make all 3 arches bigger, but I don't know the dimension limitations you are working with
under that on the same page you have a toggle between cpu, ram and network, and under that is storage, I would have it showing all stacked, but touching the label title it would collapse, so you can show or hide everything, or any combination of the four
