In Dynatrace, you have various types of metrics at your disposal:
- Built-in metrics provided by OneAgent. These have the
builtin:prefix in the metric key.
- Extension metrics provided by OneAgent or ActiveGate extensions. These have the
ext:prefix in the metric key.
- Calculated metrics you create. These have the
calc:prefix in the metric key.
- Custom metrics you can feed to Dynatrace via metric ingestion. These don't have any fixed prefix, as the ingestion protocol is completely flexible.
