I have been looking around but could not find a definite answer : What data range is used to produce the hourly and daily data points ?
To my understanding (from the documentation and ManageIQ posts I could find), an hourly data point is built by adding the data points of the following 60 minutes. For the 4:00 data point, it would mean that it was merged from any collection from 4:00 to 4:59.
What about daily points ? Providing the previous statement was correct, it would be 00:00 to 23:00 data points merged ?
Can someone correct this ? Without this information, an hourly timestamp from reports or utilization graphs is hard to understand.
The second interrogation is the Real Time metrics available for the Vcenter provider. Are they also collected every (by default) 10mins, like the other C&U data ?
This would mean that alerts based on Real Time metrics could be delayed by at most 10min, if I don’t change the default collection period.
