Below is a table of Process metric instruments.

| `process.cpu.time` | Counter | s | Total CPU seconds broken down by different states. | `state`, if specified, SHOULD be one of: `system`, `user`, `wait`. A process SHOULD be characterized _either_ by data points with no `state` labels, _or only_ data points with `state` labels. |

A process SHOULD be characterized _either_ by data points with no `state` labels, _or only_ data points with `state` labels. |
