How to create a check to alert over last 60 minutes summarized data

[newtechfellas]

I want to alert if there is no event received for an hour. I tried combinations of timeShift or summarize to use 60 minutes to grab 1 hour data. But cabot is always using only 10 minutes.

I tried summarize(production.in.event, "50min") or sum(timeShift(production.in.event, "-50min"))

or other combinations but did not get the desired sum of graphite metric for an hour. I configured the check to run every 5 minutes with a threhold "less than or equal to 0"
