These columns provide statistics on current logging characteristics and storage device information.
|Column Name||Mode||Description||Data Type|
|GmtTime||n/a||Greenwich Mean Time is not affected by the Daylight Saving Time adjustments that occur twice a year.||FLOAT|
|CabinetID||n/a||The physical cabinet number of the node.||INTEGER|
|ModuleID||n/a||The physical module number of the node.||INTEGER|
|NodeType||n/a||Type of node, representing the per node system family type.||CHAR(8)|
The value is the decimal equivalent of the three digit controller ID in the LdvId (the HHC digits).
If the controller information is not available, its value is set to -1.
In Summary Mode, the CtlId is set to -1.
|LdvName||n/a||Storage device name.||CHAR(8)|
|LdvId||n/a||Storage device in the Bus System where it resides.
If the device address information is available, the LdvId is derived from the Host, Channel, Id, and Lun information of the device (00HHCTLL).
If the device address information is not available, this column contains the null ID which is 0xFFFFFFFF.
In Summary Mode, the value is set to 0xFFFFFFFF.
|LdvType||n/a||Type of logical device. The value is either DISK for database disk or SDSK for system disk.||CHAR(4)|
|LdvKind||n/a||Type of storage device.
A value of 'HDD' indicates the storage device is a hard disk drive (HDD).
A value of 'SSD' indicates the storage device is a solid state device (SSD).
A value of 'RSSD' indicates the storage device is a read intensive solid state device.
A value of 'WSSD' indicates the storage device is a write intensive solid state device.
A value of 'NETW' indicates a network device.
In Summary mode, the value is set to ‘---’.
|Major||n/a||Major number of the device.||INTEGER|
|Minor||n/a||Minor number of the device.||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:
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|
|SummaryFlag||n/a||Summarization status of this row. If the value is 'N,' the row is a non-summary row. If the value is 'S,' the row 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_COD_CPU||n/a||Platform Metering (PM) CPU Capacity On Demand (COD) value in one tenths of percent. For example, a value of 500 represents a PM CPU COD value of 50%.
The value is set to 1000 if PM CPU COD is disabled.
|PM_COD_IO||n/a||Platform Metering (PM) I/O Capacity On Demand (COD) value in whole percent. For example, a value of 50 represents a PM I/O COD value of 50.0%.
The value is set to 100 if the PM I/O COD is disabled.
|WM_COD_CPU||n/a||Workload Management (WM) CPU Capacity On Demand (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_COD_IO||n/a||Workload Management (WM) I/O Capacity On Demand (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 WM I/O COD is disabled.
|TIER_FACTOR||n/a||I/O performance limit placed on a core-reduced node. For example, a value of 75 represents an I/O limit of 75.0% placed before other COD values.
The field is sourced from tpanodep->tierfactor, which is derived from the /proc/tdmeter/tier_performance file. A value of 100 indicates that there is no I/O performance limit applied to the node.
