Derived Metrics
- Derived metrics are calculated to simplify rule development and visualization tasks.
- The derived metrics are stored similar to original metrics and are available in rule expressions, forecasts, and widgets.
| Derived Metric | Original Metrics |
|---|---|
pcpu_total.busy | pcpu_total.sys + pcpu_total.user + pcpu_total.wait |
scpu_total.busy | scpu_total.sys + scpu_total.user + scpu_total.wait |
pcpu_total.entitled_capacity_used% | pcpu_total.busy / pcpu_total.entitled_capacity * 100 |
pcpu.total | pcpu.sys + pcpu.user + pcpu.wait — computed by tag (by processor id) |
