These columns provide the general characteristics of the housekeeping columns.
|Column Name||Mode||Description||Data Type|
|GmtTime||n/a||Greenwich Mean Time is not affected by the Daylight Savings Time adjustments that occur twice a year.||FLOAT|
|NodeType||n/a||Type of node, representing the per node system family type.||CHAR(8)|
|VprId||n/a||Identifies the vproc number (non-Summary Mode) or the vproc type (Summary Mode; 0 = NODE, 1 = AMP, 2 = PE, 3=GTW, 4=RSG, 5=TVS).||INTEGER|
|VprType||n/a||Type of vproc. The values can be NODE, AMP, PE, GTW, RSG, or TVS (see Teradata Virtual Storage).||CHAR(4)|
|Secs||n/a||Actual number of seconds in the log period represented by this row. Normally the same as NominalSecs, but can be different in three cases:
Useful for normalizing the count statistics contained in this row, for example, to a per-second measurement.
|CentiSecs||n/a||Number of centiseconds in the logging period. This column is useful when performing data calculations with small elapsed times where the difference between centisecond-based data and whole seconds results in a percentage error.||INTEGER|
|NominalSecs||n/a||Specified or nominal number of seconds in the logging period.||SMALLINT|
|NCPUs||n/a||Number of CPUs on this node.
This column is useful for normalizing the CPU utilization column values for the number of CPUs on the node. This is especially important in coexistence systems where the number of CPUs can vary across system nodes.
|SummaryFlag||n/a||Summarization status of this row. Possible values are 'N' if the row is a non-summary row and 'S' if it is a summary row.||CHAR (1)|
|Active||max||Controls whether or not the rows will be logged to the resource usage tables if Active Row Filter Mode is enabled.
If Active is set to a non-zero value, the row contains data columns.
If Active is set to a zero value, none of the data columns in the row have been updated during the logging period.
For example, if you enable Active Row Filter Mode, the rows that have a zero Active column value will not be logged to the resource usage tables.
|TheTimestamp||n/a||Number of seconds since midnight, January 1, 1970.
This column is useful for aligning data with the DBQL log.
|PM_CPU_COD||n/a||Platform Metering CPU COD value in one tenths of a percent. For example, a value of 500 represents a PM CPU COD value of 50.0%.
The value is set to 1000 if the PM CPU COD is disabled.
|WM_CPU_COD||n/a||Workload Management CPU COD value in one tenths of a percent. For example, a value of 500 represents a WM CPU COD value of 50.0%.
The value is set to 1000 if the WM CPU COD is disabled.
WM CPU COD is not supported on SLES 10. Its value is set to 1000 on SLES 10.
