The following metrics are available to analyze resource usage for a Teradata Aster system.
| Metric | Description | Type |
|---|---|---|
| Active Processes | Processes that are currently running | Number |
| Components Down | Nodes that are not available | Number |
| Components Passive | Nodes not processing queries but can be made ready to process queries when needed | Number |
| CPU | Average node CPU use | Percent |
| Disk I/O | Data transfer rate, in bytes per second | Number |
| Disk In | Rate of disk writes, in bytes per second | Number |
| Disk Out | Rate of disk reads, in bytes per second | Number |
| Max Disk By Node | For the node with the most used disk space, the amount of used disk space on the node | Percent |
| Memory | Average node memory use | Percent |
| Network In | Rate of network traffic into the node, in bytes per second | Number |
| Network Out | Rate of network traffic out of the node, in bytes per second | Number |
| Node CPU Skew | Comparison of CPU use on the busiest node to the average node | Percent |
| Node I/O Skew | Comparison of I/O use on the busiest node to the average node | Percent |
| Queen Disk Space | Used disk space on the queen node | Percent |
| Session Login Count | Sessions currently logged on to the system | Number |
| Total Space | Used disk space on the system | Percent |
