END OF INNODB TABLESPACE MONITOR OUTPUT
=======================================
The Tablespace Monitor output includes information about the shared tablespace as a whole, followed
by a list containing a breakdown for each segment within the tablespace.
The tablespace consists of database pages with a default size of 16KB. The pages are grouped into
extents of size 1MB (64 consecutive pages).
The initial part of the output that displays overall tablespace information has this format:
FILE SPACE INFO: id 0
size 13440, free limit 3136, free extents 28
not full frag extents 2: used pages 78, full frag extents 3
first seg id not used 0 23845
Overall tablespace information includes these values:
• id: The tablespace ID. A value of 0 refers to the shared tablespace.
• size: The current tablespace size in pages.
• limit: The minimum page number for which the free list has not been initialized. Pages at or
free
above this limit are free.
• extents: The number of free extents.
free
•
not full frag extents,
filled, and the number of pages in those extents that have been allocated.
• extents: The number of completely full fragment extents.
full frag
•
first seg id not
Individual segment information has this format:
SEGMENT id 0 15 space 0; page 2; res 160 used 160; full ext 2
fragm pages 32; free extents 0; not full extents 0: pages 0
Performance Tuning and Troubleshooting
pages: The number of fragment extents that are not completely
used
used: The first unused segment ID.
