Memory File Usage -m

The ctstat utility supports an option, -m, that when specified with the -vaf report option, causes ctstat to output the following additional memory file statistics:

• phyrec - Last byte offset of file for non-memory file or current memory in use for memory file.
• mhghbyt - Largest amount of memory used for memory file since file was created.
• memcnt - Current number of memory records.
• hghcnt - Largest number of memory records since file was created.
