I am trying to build a simple report to show node availability per month but am not confident that the % number returned in the 'Historical Availability' reports are correct. When I create a report that shows event down time and event up time, it shows the time in hours, mins and seconds but I can see that the 'minutes down' downtime figure reporting back is rounded to the nearest minute. Is there any documentation that explains in detail how the figures are calculated in the tool?
Thanks
