I have the below query that gives me 168h delta percentage. However, I would like to get delta for (current value - time0 value). Here time0 value is the value at, lets say value@timestamp 2024-11-07 00:00:00). How can i do that/modify below query so that i can get true delta (compared to time0 value)
(100 * (avg by(host, id, location) (delta(idle_power{location=“us”}[168h])) / (avg by(host, id, location) (idle_power{location=“us”}))))
