Challenge
Performance reports may be missing data if data collection is set to run every 4 hours or more frequently because a vCenter Server updates the history table only once every few hours.
Cause
Performance reports are not updated because vCenter Server updates the history table only once every few hours.
Solution
As of Version 8.0 Collection jobs cannot be scheduled in more than 3 hour intervals. If data issues persist adjust to run your collection jobs to run every 8 hours, but not more often. This will guarantee the performance data will be collected correctly.
