Server Status Variables The number of events discarded from the Performance Schema  error_log  table to make room for new events. The number of events currently present in the Performance Schema  error_log  table. As with Error_log_buffered_bytes , it is possible for the value to decrease. This variable was added in MySQL 8.0.22. This variable was added in MySQL 8.0.22. • Error_log_buffered_events • Error_log_expired_events • Error_log_latest_write • Flush_commands • group_replication_primary_member The number of times the server flushes tables, whether because a user executed a  FLUSH TABLES statement or due to internal server operation. It is also incremented by receipt of a  COM_REFRESH packet. This is in contrast to  Com_flush , which indicates how many  FLUSH  statements have been executed, whether  FLUSH TABLES ,  FLUSH LOGS , and so forth. This variable was added in MySQL 8.0.22. The time of the last write to the Performance Schema  error_log  table. This variable was added in MySQL 8.0.22. Shows the primary member’s UUID when the group is operating in single-primary mode. If the group is operating in multi-primary mode, shows an empty string. The  group_replication_primary_member  status variable is deprecated and is scheduled to be removed in a future version. The number of internal  COMMIT  statements. The number of times that rows have been deleted from tables. The server increments this variable for each call to its  external_lock()  function, which generally occurs at the beginning and end of access to a table instance. There might be differences among storage engines. This variable can be used, for example, to discover for a statement that accesses a partitioned table how many partitions were pruned before locking occurred: Check how much the counter increased for the statement, subtract 2 (2 calls for the table itself), then divide by 2 to get the number of partitions locked. The number of times the server uses a storage engine’s own Multi-Range Read implementation for table access. • Handler_mrr_init • Handler_external_lock • Handler_delete • Handler_commit 954
