Recently i discovered my bill raising without using anything above free tier of with very minor charges. On the bill management page it was clear that the charges are coming from CloudWatch Alarms as you can see in the picture below.
My question is why and how can i stop them? I can see that the alarms are been created by DynamoDB auto-scaling, but i can't continue being charged for such a simple thing, i'm sure there is an option to disable it but i can't figure out.
Edited I checked "hide auto-scaling alarms" box but i think it's not the fix, fingers crossed to be:P
AWS Free Tier includes 10 Alarm metrics (not applicable to high-resolution alarms).
See How can I determine why I was charged for CloudWatch usage, and then how can I reduce future charges?
