You want to use one of the "over time" functions. avg_over_time(cpu_utilization[1d]) < 0.10
quantile_over_time(0.9 cpu_utilization[1d]) < 0.10 On Sat, Apr 3, 2021 at 1:34 AM chuanjia xing <[email protected]> wrote: > Hi there, > I think my question is pretty common but looks like I can't find the > answer to it. > The problem I am trying to solve is: Let's say I have 100 metrics > data for cpuutilization for my instance.
