If I run a report for the last 7 days on any of my reportable data, I am missing everything from 6/24 at about 10:30 PM through 6/27 at about 6:15 AM.  If I run the report for a custom range that includes those days, the data is present.  It appears to be happening when the data points change from 'Recorded' to 'Hourly' intervals.  For example, on one server I have 15 minute recording intervals for Memory Utilization.  If the report shows 15 minute data points, it shows from 6/24 to 6/27 (like a custom report from 6/23 to 6/29).  If the report uses 1 hour data points, the 25'th and 26'th are gone (such as 'Last 7 Days').

 

If there are any logs or images you would like, please let me know.
