In this case, the total  column values for index memory are slightly higher than the value set of IndexMemory  due to internal rounding. 

For the used_pages  and total_pages  columns, resources are measured in pages, which are 32K in size for DataMemory  and 8K for IndexMemory . For long message buffer memory, the page size is 256 bytes.
