These columns provide a generalized picture of the vprocs running on this node, shown as Type n virtual processors where n = 1 to 7. Under the current implementation, only Type 1 (AMP), Type 2 (PE), Type 3 (GTW), Type 4 (RSG), and Type 5 (TVS) vprocs exist; vproc types 6 through 7 are not currently used.

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)
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.

SMALLINT
Vproc1 n/a Current count of type 1 (AMP) virtual processors running under the node. SMALLINT
Vproc2 n/a Current count of type 2 (PE) virtual processors running under the node. SMALLINT
Vproc3 n/a Current count of type 3 (GTW) virtual processors running under the node. SMALLINT
Vproc4 n/a Current count of type 4 (RSG) virtual processors running under the node. SMALLINT
Vproc5 n/a Current count of type 5 (TVS) virtual processors running under the node. SMALLINT
Vproc6 n/a Current count of type 6 virtual processors running under the node.

This column reports zeros.

SMALLINT
Vproc7 n/a Current count of type 7 virtual processors running under the node.

This column reports zeros.

SMALLINT
VprocType1 n/a Type of virtual processor for Vproc1. Value is always AMP. CHAR(4)
VprocType2 n/a Type of virtual processor for Vproc2. Value is always PE. CHAR(4)
VprocType3 n/a Type of virtual processor for Vproc3. Value is always GTW. CHAR(4)
VprocType4 n/a Type of virtual processor for Vproc4. Value is always RSG. CHAR(4)
VprocType5 n/a Type of virtual processor for Vproc5. The value is always TVS (see Teradata Virtual Storage). CHAR(4)
VprocType6 n/a The type of virtual processor for Vproc6. CHAR(4)
VprocType7 n/a The type of virtual processor for Vproc7. CHAR(4)
MemSize n/a Amount of memory on this node in megabytes. Useful for performing memory usage calculations. BIGINT
NodeNormFactor n/a A per CPU normalization factor that is used to normalize the reported CPU values of the ResUsageSpma table to a single 5100 CPU.

This value is scaled by a factor of 100. For example, if the actual factor is 5.25, the value of the NodeNormFactor will be 525.

The normalization factor is related to the NodeType value reported in the ResUsageSpma table.

For information on this value, see ResUsageSpma Table.

INTEGER
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:
  • The first interval after a log rate change
  • A sample logged late because of load on the system
  • System clock adjustments affect reported Secs

Useful for normalizing the count statistics contained in this row, for example, to a per-second measurement.

SMALLINT
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
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.

FLOAT
TheTimestamp n/a Number of seconds since midnight, January 1, 1970. BIGINT
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.

SMALLINT
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.
SMALLINT
PM_IO_COD n/a Platform Metering I/O COD value in whole percent values for the entire system. For example, a value of 50 represents a PM I/O COD value of 50%.

The value is set to 100 if the PM I/O COD is disabled.

SMALLINT
WM_IO_COD n/a Workload Management I/O COD value in whole percent. For example, a value of 50 represents a WM I/O COD value of 50.0%.

The value is set to 100 if the WM I/O COD is disabled.

WM I/O COD is not supported on SLES 10. Its value is set to 100 on SLES 10.
