Server Status Variables The number of requests to insert a row in a table. The progress of an operation to record the pages held in the  InnoDB  buffer pool, triggered by the setting of  innodb_buffer_pool_dump_at_shutdown  or  innodb_buffer_pool_dump_now . For related information and examples, see Section 15.8.3.6, “Saving and Restoring the Buffer Pool State” . The progress of an operation to warm up the  InnoDB  buffer pool by reading in a set of pages corresponding to an earlier point in time, triggered by the setting of innodb_buffer_pool_load_at_startup  or  innodb_buffer_pool_load_now . If the operation introduces too much overhead, you can cancel it by setting  innodb_buffer_pool_load_abort . For related information and examples, see Section 15.8.3.6, “Saving and Restoring the Buffer Pool State” . The total number of bytes in the  InnoDB  buffer pool containing data. The number includes both dirty and clean pages. For more accurate memory usage calculations than with Innodb_buffer_pool_pages_data , when compressed tables cause the buffer pool to hold pages of different sizes. The total current number of bytes held in dirty pages in the  InnoDB  buffer pool. For more accurate memory usage calculations than with  Innodb_buffer_pool_pages_dirty , when compressed tables cause the buffer pool to hold pages of different sizes. The current number of dirty pages in the  InnoDB  buffer pool. The number of requests to flush pages from the  InnoDB  buffer pool. The number of free pages in the  InnoDB  buffer pool. The number of latched pages in the  InnoDB  buffer pool. These are pages currently being read or written, or that cannot be flushed or removed for some other reason. Calculation of this variable is expensive, so it is available only when the  UNIV_DEBUG  system is defined at server build time. • Innodb_buffer_pool_pages_misc • Innodb_buffer_pool_pages_latched • Innodb_buffer_pool_pages_free • Innodb_buffer_pool_pages_flushed • Innodb_buffer_pool_pages_dirty • Innodb_buffer_pool_bytes_dirty • Innodb_buffer_pool_pages_data • Innodb_buffer_pool_bytes_data • Innodb_buffer_pool_load_status • Innodb_buffer_pool_dump_status 956 The number of pages in the  InnoDB  buffer pool containing data. The number includes both dirty and clean pages. When using compressed tables, the reported  Innodb_buffer_pool_pages_data  value may be larger than  Innodb_buffer_pool_pages_total  (Bug #59550).
