USAGE EXAMPLE

The absolute function is useful when you are interested in monitoring only the difference between two metrics.

For example, a retail organization wants to verify that (a) inventory data produced by their internal system matches (b) the sales reports they are getting from their partners. If they subtract one from the other, it should be very close or identical. In case there is a significant difference between the two, the system will identify it as an anomaly and trigger an alert.

How to set it up?

Step 1: Use the function pairs to subtract one set of metrics from the other.
Step 2: Add the absolute function on top of the pairs function.
