| Metric | Description |
|---|---|
| Active Sessions | Number of sessions with active queries |
| AMP CPU Skew | Comparison of CPU use on the busiest AMP to the average AMP |
| AMP I/O Skew | Comparison of disk use on the busiest AMP to the average AMP |
| AMP Worker Tasks | Average number of AMP worker tasks in use on each AMP |
| Component Down | Number of components, such as BYNETs or AMPs, that are down |
| (CPU) System | Average CPU time spent executing kernel system calls or servicing I/O and timer hardware interrupts |
| (CPU) User | Average CPU time spent executing code on behalf of operating system user processes |
| CPU Utilization | Average node CPU use. CPU is calculated as the sum of the user CPU, system CPU, and wait I/O usage percentages, depending on which of these are enabled by the Teradata Viewpoint Administrator in the Monitored Systems portlet |
| (CPU) Wait I/O | Average percentage of CPU time spent waiting for I/O |
| DBC Disk Space | Available DBC disk space in use |
| Enabled CPU Usage In Viewpoint Mobile view this metric is currently not available.
|
CPU utilization based on enabled CPUs for IFX 2.1 and higher systems with Elastic TCore enabled |
| Max Disk by AMP | Available disk space currently in use |
| Max Spool by AMP | Available spool space in use |
| Memory Used | Represents an increase or decrease in the node-level memory. A null value or negative number reports as 0. |
| Node CPU Skew | Comparison of CPU use on the busiest node to the average node |
| Node I/O Skew | Comparison of disk use on the busiest node to the average node |
| System Heartbeat | Canary query showing the response time of the most recent system heartbeat in milliseconds |
| Total Disk Space | Percentage of total disk space currently in use |
| Additional Canaries | Additional canary queries that are defined for the system and used as part of the monitoring of system health |
