研究方向
The issue reports that FREE BUFFER and TOTAL BUFFER values remain constant at 343597383680 despite configuration changes. The research should start by examining the source code for the 'show @@processor' command, likely in the monitoring module. Look for buffer allocation logic and how FREE BUFFER and TOTAL BUFFER are computed. Also check the parsing of server.xml to ensure buffer parameters like processorBufferPool or similar are being read correctly. Review the user's configuration to understand what settings they changed. Finally, verify if there is a known bug or limitation in the buffer management code.
