grafana v7.0.5 — and graphite.
I plotted out run completion time each day (M-F) for a specific task. Using Max value each day for series.
I am trying to create a threshold line with standard deviation that will look back N days worth of data.
Query looks historical 30 days and gets average completion time is 20:00 and 1 std dev is +/- 10min
so line will be across 20:10 and 17:50 filled which will represent normal runtime of this task.
Is this do-able? if yes, how?
