To optimize user experience, TencentDB for MongoDB has to modify the statistical method of the monitoring metric "Capacity Utilization" in November, 2020.

• The current statistical method calculates the average value of capacity utilization of multiple nodes, while the new method will calculate the minimum value of capacity utilization of multiple nodes.
• The minimum value also decides whether TencentDB for MongoDB should lock an instance due to the instance capacity being fully utilized.
• During the modification, it is normal if the capacity utilization of your disk is temporarily reduced.
