The block cache has always been set to 24GB, and the metric value observed in monitoring system is also 24GB. However, after Pegasus is upgraded from 2.0 to 2.4, the metric value becomes incorrect. As is shown in the following graph, the left side is the usage of the block cache before the upgrade, which is correct value; the right side is the usage after the upgrade, which is always 0 and incorrect:  The following graph is the usage of physical memory with the time corresponding to the above graph, which is correct:  It's obvious that the replica server has been started and the block cache usage should has become 24GB, which is still actually 0. Then, restart the replica servers and their usage of block cache become non-zero values; however, After a short while , the growth stopped and it stayed at a fixed value forever which is incorrect:  Similarly, the following graph is the usage of physical memory with the time corresponding to the above graph, which is also correct:  -- This is an automated message from the Apache Git Service.
