This metric will be collected by instrumenting the following functions:

WiredTigerRecordStore::_insertRecords()

WiredTigerRecordStore::updateRecord()

WiredTigerRecordStore::updateWithDamages()

WiredTigerRecordStore::deleteRecord()

 

Note that this should strictly capture the use of WT_CURSOR insert(), modify(), and remove() calls.  Uses of modify() should count the number of bytes in the modify call, not the number of bytes in the resulting record after the modification.  Uses of remove() should count the number of bytes in the record prior to removal.
