How to set up alarm for 'n' appsCompleted Metrics in EMR per day in AWS console
When I set up alarm for appsCompleted<12 for 1 out of 1 datapoints it says that the alarm will go off in the following scenario:
appsCompleted
This alarm will trigger when the blue line goes below the red line for 1 datapoints within 1 day
This alarm will trigger when the blue line goes below the red line for 1 datapoints within 1 day
But it does not seem to change the threshold by adding up values per day. That is the next days threshold is still 12 and not 24. I suspect that the threshold (red line) is crossed on the first day itself and that is why no alarms are triggered even in case of failure.
State changed to OK at [DATE]. Reason: Threshold Crossed: 1 out of the last 1 datapoints [Timestamp] was not less than the threshold (12.0) (minimum 1 datapoint for ALARM -> OK transition).

If I increase the m value the n value also forced increase by the console and vice verse. How do I set up an alarm that triggers if 12 jobs didn't complete per day.
@Tartaglia There are 12 appsCompleted metrics each day. I want to keep a check on any failure. It'll be better non cumulative.

Is this a cumulative metric? Do you expect to see datapoints with values 12, 12, 12 ... or 12, 24, 36, ... ?
