-- View: metrics -- -- Creates a union of the following information: -- -- * performance_schema.global_status -- * information_schema.INNODB_METRICS -- * Performance Schema global memory usage information -- * Current time -- -- This is the same as the metrics_56 view with the exception that the global status is taken from performance_schema.global_status instead of -- from the Information Schema. Use this view if the MySQL version is 5.7.6 or later and show_compatibility_56 = OFF. -- See also https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_show_compatibility_56 -- -- For view has the following columns: -- -- * Variable_name: The name of the variable -- * Variable_value: The value of the variable -- * Type: The type of the variable. This will depend on the source, e.g. Global Status, InnoDB Metrics - ..., etc. -- * Enabled: Whether the variable is enabled or not. Possible values are 'YES', 'NO', 'PARTIAL'. -- PARTIAL is currently only supported for the memory usage variables and means some but not all of the memory/% instruments -- are enabled. -- -- mysql> SELECT * FROM metrics; -- +-----------------------------------------------+-------------------------...+--------------------------------------+---------+ -- | Variable_name | Variable_value ...| Type | Enabled | -- +-----------------------------------------------+-------------------------...+--------------------------------------+---------+ -- | aborted_clients | 0 ...| Global Status | YES | -- | aborted_connects | 0 ...| Global Status | YES | -- | binlog_cache_disk_use | 0 ...| Global Status | YES | -- | binlog_cache_use | 0 ...| Global Status | YES | -- | binlog_stmt_cache_disk_use | 0 ...| Global Status | YES | -- | binlog_stmt_cache_use | 0 ...| Global Status | YES | -- | bytes_received | 217081 ...| Global Status | YES | -- | bytes_sent | 27257 ...| Global Status | YES | -- ... -- | innodb_rwlock_x_os_waits | 0 ...| InnoDB Metrics - server | YES | -- | innodb_rwlock_x_spin_rounds | 2723 ...| InnoDB Metrics - server | YES | -- | innodb_rwlock_x_spin_waits | 1 ...| InnoDB Metrics - server | YES | -- | trx_active_transactions | 0 ...| InnoDB Metrics - transaction | NO | -- ... -- | trx_rseg_current_size | 0 ...| InnoDB Metrics - transaction | NO | -- | trx_rseg_history_len | 4 ...| InnoDB Metrics - transaction | YES | -- | trx_rw_commits | 0 ...| InnoDB Metrics - transaction | NO | -- | trx_undo_slots_cached | 0 ...| InnoDB Metrics - transaction | NO | -- | trx_undo_slots_used | 0 ...| InnoDB Metrics - transaction | NO | -- | memory_current_allocated | 138244216 ...| Performance Schema | PARTIAL | -- | memory_total_allocated | 138244216 ...| Performance Schema | PARTIAL | -- | NOW() | 2015-05-31 13:27:50.382 ...| System Time | YES | -- | UNIX_TIMESTAMP() | 1433042870.382 ...| System Time | YES | -- +-----------------------------------------------+-------------------------...+--------------------------------------+---------+ -- 412 rows in set (0.02 sec)
