Alerts based on graphite data are evaluating to null values even though the metric returns valid plot points

Hi Danielle,

Yes, I did resolve it, and your assumption is correct, the data is written to the DB once a day, so indeed, the last 5 minutes had no data to show, I changed the time filter to be (25h,now) and that seems to work. The alert fires whenever the threshold is met.

Thanks for your response!

Regards,
Cesar
