AWS:Track costs

One time

• 1. management console -> billing
• 2. cost allocation tags
• 3. AWS-generated cost allocation tags  tab
• 4. turn them all on. but in retrospect, you might only need to activate aws:autoscaling:groupName

now run your jobs wait until your billing cycle resets. It seems to be around 11 am PT. I am not at all sure why that is

Every time

• 1. management console -> billing
• 2. cost management -> cost explorer (left side)
• 3. daily spend view.
• 4. click to select relevant days in the calendar.
• 5. (top right of chart) more -> Tag -> autoscaling:group name

now you can see how much you spend on each job on a particular day (which I think ends at 5pm PT which is 0h GMT currently.
