I have a dashboard that queries a graphite db and pulls data once a day, the data has the range of 0-1.0 (i.e. 0.997, 0.9998, and so forth), I am trying to set an alert for when those values fall below a threshold.
The below is what the graph looks like:
Clearly, one can see that data is being returned, however, in the alert section, the query returns null values that I cannot evaluate.
From the above one can see all the points have a value of null (not true based on the previous image)
I have tried every function available, they all return null, except for count, which returns the number of points (5, which is not helpful for my purpose). Any idea why this might be happening?
