Select metrics to appear in the summary and details views for nodes, vprocs, AMPs, and PEs.
If the processing is skewed towards one or more AMPs (that is, the parallelism is not 100%), the metrics may display a value greater than 100% do to the way the data is normalized.
Some metrics are available only in certain views.

A 1024 byte kilobyte is used as the base for all memory-related and space-related metrics that display, such as spool space, disk space, memory usage, and so on. A 1000 byte kilobyte is used as the base for all other metrics.
| Metric | Description | Type | View |
|---|---|---|---|
| AMP Count | Number of AMPs on the node | Number | N |
| Available AWTs for New Work | Total unused AMP worker tasks available for new work (WorkNew/Work00). The WorkNew (Work00) work type is limited by default to 50 AWTs. If 50 AWTs are already in-use servicing WorkNew message types, there may still be AWTs in the unreserved pool that under this definition will not be considered available. | Number | V |
| Available Unreserved AWTs | (Teradata Database 16.0 and later) Total unused AMP worker tasks for the entire unreserved pool (all work types). This is the number of AWTs available in the unreserved pool able to be used by all work types in combination, not limited to WorkNew work types. | Number | V |
| AWTs In Use | Total in-use AMP worker tasks (all work types) | Number | V |
| Clique Number | The clique number of the node | Number | N |
| Cluster Number | Cluster to which the AMP is assigned | Number | V |
| CPU AWT | Percent of CPU usage by AMP worker tasks | Percent | V |
| CPU I/O Wait | Percent of CPU resources in idle and waiting for I/O completion | Number | N |
| CPU PE | Percent of CPU usage in PE dispatcher processing | Percent | V |
| CPU System | Percent of CPU usage spent in user service processing | Percent | N, V |
| CPU Usage | Percent of CPU usage | Percent | N, V |
| CPU Use Monitor Virtual Resource | Percent of CPU usage not spent being idle from Monitor Virtual Resource PM/API | Percent | V |
| CPU User | Percent of CPU usage spent in non-service user code processing | Percent | N |
| Disk I/O | Number of disk I/Os | Number | N, V |
| Disk Out Req Avg | Average number of outstanding disk requests | Number | N, V |
| Disk Reads | Total physical disk reads | Number | N, V |
| Disk Usage | Percentage of disk usage | Percent | N, V |
| Disk Writes | Total physical disk writes | Number | N, V |
| Host Block Reads | Message blocks received from all hosts | Number | N, V |
| Host Block Writes | Message blocks sent to all hosts | Number | N, V |
| Host ID | Identifier of the host or LAN associated with the PE | Number | V |
| Host I/O | Number of host I/Os | Number | N, V |
| Max I/O Response | Maximum I/O response time for the AMP | Number | V |
| Mem Allocate KB | Change in vproc memory from the previous sample time frame | Number | N, V |
| Mem Allocates | Segments allocated to memory resources | Number | V |
| Message Count | Messages currently queued for delivery to an AMP | Number | V |
| Message DQ Count | Messages dequeued by an AMP | Number | V |
| Net A Usage | Total BYNET utilization | Percent | N |
| Net I/O | Number of messages between the node and the BYNET | Number | N, V |
| Net Reads | Messages read from the BYNET and input into the node | Number | N, V |
| Net Writes | Messages written from the node and output to the BYNET | Number | N, V |
| Node ID | Node identifier (cabinet ID and node ID) | Number | N, V |
| Node Type | Type of node | Various | N |
| PE Count | Number of active PEs on the node | Number | N |
| Session Log Count | Number of sessions currently logged on to the PE | Number | V |
| Session Run Count | Number of current sessions whose Initiate Requests (TSR messages) are addressed to this vproc | Number | V |
| Status | Status of the vproc | Character | N, V |
| Swaps | Number of segments swapped between memory and disk | Number | N |
| Swap Reads | Segments read into node memory from the disk due to swapping | Number | N |
| Swap Writes | Segments written to disk from node memory due to swapping | Number | N |
| Vproc ID | Vproc identifier | Number | V |
| Vproc Type | Type of vproc | Character | V |
