26.4.3.19 The memory_global_by_current_bytes and x$memory_global_by_current_bytes Views

These views summarize memory use, grouped by allocation type (that is, by event). By default, rows are sorted by descending amount of memory used.

The memory_global_by_current_bytes and x$memory_global_by_current_bytes views have these columns:

• event_name

  The memory event name.

• current_count

  The total number of occurrences of the event.

• current_alloc

  The current number of allocated bytes that have not been freed yet for the event.

• current_avg_alloc

  The current number of allocated bytes per memory block for the event.

• high_count

  The high-water mark for number of memory blocks allocated for the event.

• high_alloc

  The high-water mark for number of bytes allocated for the event.

• high_avg_alloc

  The high-water mark for average number of bytes per memory block allocated for the event.
