I have a multi-dimension time-series created based on the values of a label of a single time series , as shown in the image . Now I need an alert when a time series deviates more than the threshold value of standard deviation which is calculated from the value of each graph at that particular point of time .

for example at 17:58:30 , I need to calculate the standard deviation based on values of all time-series value at that time. And then find out if any time series is exceeding the threshold value at that particular time and should trigger alert if any
