So, I have sql-toolkit sampler setup which runs a query select a,b from c where some condition. I also have a rule setup, target being number of rows returned by above sampler, idea being: if number of rows > 0, then raise an alarm.
That works just fine; what I need to know is, how can I capture returned value of column "a" and use it inside the rule to, for instance, format Subject.
Thanks, Michael
