Yes , you right 100% , for now im running unraid on i5 only 4 core ,24gb , so im also want monitor only what needed , also having some dockers runs, but really didnt checked yet what tool best for me and how much power will take to monitor all staff of unraid .
So for now native dashboard is good for me , msi afterburner and adguard is very interested to monitor for me for now ...
howere adguard also have own dashboard....
