collect interval are not detected.
Transients-Opens.nb (*) Number of opens occurring during the measurement period.

NOTE:
DISKFILE is the more costly measurement. We should restrict the number of entities in this domain. FILESIZE should
be a preferred if possible.
3-8 FILESIZE
The FILESIZE domain represents the features of a disk file.
3-8-1 FILESIZE Instance Configuration
Domain
FILESIZE
DescriptionDomain
FILESIZE represents features of a disk file.
Syntax
FILESIZE <$Volume>.<Subvolume>.<File> [,TREND=<ON|OFF>]
[,PARTONLY]
Example FILESIZE $DATA.DATABASE.FILE2
When a non-SQL partitioned file is configured for monitoring, the default size metrics
reported for the primary partition are those for the logical file, i.e. the sum of all the
partitions. You can add a PARTONLY parameter to the primary partition definition to
force the collection for the partition rather than for the file as a whole.
Comments
OVNPM accepts four data parameters in the subvolume and file specifications. The
feature enhances OVNPM capability to monitor files with date-time stamped names.
These parameters are:
%yyyy% := Whole year
%yy% := Year
%mm% := Month
%dd% := Day
and a combination of these parameters:
%mmdd% := Month & Day
%yymmdd% := Year, Month & Day
The part of the filename that contains the date parameters is displayed in the Display
Agent in lowercase.
