I have a datadog alert with a simple metric query which simply sums the successful calls and the calls which failed (errors) - they are variables named a and b. and the metric function is (a / (a + b)) * 100 and i get the alert if it drops from my threshold (< 90). I want to know the values of a and b (the metric variables) in the notification message i get when the alert pops. Also, is there a way to add another limit to the alert to only go off when the threshold is passed and also let's say a + b > 100.

Couldn't find any guide or information regarding this questions, would mean a lot if you can help me with this :)
