Member Data Documentation

ulint_ctr_1_t srv_stats_t::buf_pool_flushed

Count the number of pages that were written from buffer

pool to the disk

Definition at line 99 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::buf_pool_reads

Number of buffer pool reads that led to the reading of

a disk page

Definition at line 103 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::buf_pool_wait_free

Store the number of times when we had to wait for a free page

in the buffer pool. It happens when the buffer pool is full and we need to make a flush, in order to be able to read or create a page.

Definition at line 95 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::buf_pool_write_requests

Store the number of write requests issued

Definition at line 90 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::data_read

Number of data read in total (in bytes)

Definition at line 106 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::data_written

Count the amount of data written in total (in bytes)

Definition at line 64 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::dblwr_pages_written

Store the number of pages that have been flushed to the

doublewrite buffer

Definition at line 87 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::dblwr_writes

Count the number of times the doublewrite buffer was flushed

Definition at line 83 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::log_waits

We increase this counter, when we don't have enough

space in the log buffer and have to flush it

Definition at line 80 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::log_write_requests

Number of the log write requests done

Definition at line 67 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::log_writes

Number of physical writes to the log performed

Definition at line 70 of file srv0srv.h.

ulint_ctr_1_t srv_stats_t::n_lock_wait_count

Number of database lock waits

Definition at line 112 of file srv0srv.h.

lint_ctr_1_t srv_stats_t::n_lock_wait_current_count

Number of threads currently waiting on database locks

Definition at line 115 of file srv0srv.h.

ib_int64_ctr_1_t srv_stats_t::n_lock_wait_time

Wait time of database locks

Definition at line 109 of file srv0srv.h.

ulint_ctr_64_t srv_stats_t::n_rows_deleted

Number of rows deleted

Definition at line 124 of file srv0srv.h.

ulint_ctr_64_t srv_stats_t::n_rows_inserted

Number of rows inserted

Definition at line 127 of file srv0srv.h.

ulint_ctr_64_t srv_stats_t::n_rows_read

Number of rows read.

Definition at line 118 of file srv0srv.h.

ulint_ctr_64_t srv_stats_t::n_rows_updated

Number of rows updated

Definition at line 121 of file srv0srv.h.

lint_ctr_1_t srv_stats_t::os_log_pending_writes

Number of writes being done to the log files

Definition at line 76 of file srv0srv.h.

lsn_ctr_1_t srv_stats_t::os_log_written

Amount of data written to the log files in bytes

Definition at line 73 of file srv0srv.h.
