|Global references (all)
|Logical count of accesses to globals, including Sets, Kills, $Data, $Order, $Increment, $Query, and global references in expressions.
|Global update references
|Logical count of global references that are Sets, Kills, or $Increments.
|Private global references
|The count of all process private global accesses.
|Private update references
|The count of process private global references that are SETs or KILLs, etc.
|Number of calls to a routine.
|Routine buffer loads and saves
|Total number of routine loads and saves as a result of ZLoad, ZSave, and running routines. (In a well-tuned environment, this number increases slowly, since most routine loads are satisfied by the routine cache memory without accessing the disk. Each routine load or save transfers up to 32 KB of data (64 KB for Unicode).)
|Number of routine commands executed since system startup.
|Routine not cached
|Number of routines not cached in memory. This information help you determine whether or not the routine buffer cache is adequately sized.
|Logical block requests
|Number of database blocks read by the globals database code. (In a well-tuned environment, many of these reads are satisfied without disk access.)
|Number of physical database blocks read from disk for both global and routine references.
|Number of physical database blocks written to disk for both global and routine references.
|Number of writes to the write image journal file.
|Number of all global references divided by the number of physical block reads and writes. Not a percentage.
|Number of journal records created—one for each database modification (Set , Kill, etc.) or transaction event (TStart, TCommit) or other event that is saved to the journal.
|Journal Block Writes
|Number of 64-KB journal blocks written to the journal file.
