sys Schema Views The current number of allocated bytes per memory block for the event. The high-water mark for number of memory blocks allocated for the event. The high-water mark for number of bytes allocated for the event. The high-water mark for average number of bytes per memory block allocated for the event. These views summarize total memory use within the server. The  memory_global_total  and  x$memory_global_total  views have these columns: The total bytes of memory allocated within the server. This view summarizes MySQL server metrics to show variable names, values, types, and whether they are enabled. By default, rows are sorted by variable type and name. The  metrics  view includes this information: There is some duplication of information between the  global_status  and  INNODB_METRICS  tables, which the  metrics  view eliminates. The  metrics  view has these columns: The metric name. The metric type determines the source from which the name is taken: The metric value. The metric type determines the source from which the value is taken: •For global status variables: The  VARIABLE_VALUE  column of the  global_status  table • Variable_value •For other metrics: A view-provided descriptive string •For  InnoDB  metrics: The  NAME  column of the  INNODB_METRICS  table •For global status variables: The  VARIABLE_NAME  column of the  global_status  table • Variable_name •The current time (human readable and Unix timestamp formats) •Current and total memory allocation, based on the Performance Schema memory instrumentation • InnoDB  metrics from the  INFORMATION_SCHEMA INNODB_METRICS  table •Global status variables from the Performance Schema  global_status  table • total_allocated 28.4.3.21 The metrics View 28.4.3.20 The memory_global_total and x$memory_global_total Views • high_count • high_alloc • high_avg_alloc 5156
