I had my time range set to last 2 days. When I viewed metric data, it was missing data for almost the last hour. It's because based on the calculations, we query from the 1H table, because the time range coincided with the data purge range. However, it led to a strange display where a platform would be green in browse resources and on the dashboard, but when you drill down, the availability lights might be grey and red. The right thing to do is to select from the detailed table as long as there is data.
