`gcp.apphub.service.criticality_type` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
| Value | Description | Stability |
|---|---|---|
| `HIGH` | High impact. |  |
| `LOW` | Low impact. |  |
| `MEDIUM` | Medium impact. |  |
| `MISSION_CRITICAL` | Mission critical service. |  |

`gcp.apphub.service.environment_type` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
| Value | Description | Stability |
|---|---|---|
| `DEVELOPMENT` | Development environment. |  |
| `PRODUCTION` | Production environment. |  |
| `STAGING` | Staging environment. |  |

## GCP Client Attributes
Attributes for Google Cloud client libraries.
| Attribute | Type | Description | Examples | Stability |
|---|---|---|---|---|
| `gcp.client.service` | string | Identifies the Google Cloud service for which the official client library is intended. [5] | `appengine`; `run`; `firestore`; `alloydb`; `spanner` |  |
**[5] `gcp.client.service`:** Intended to be a stable identifier for Google Cloud client libraries that is uniform across implementation languages. The value should be derived from the canonical service domain for the service; for example, 'foo.googleapis.com' should result in a value of 'foo'.
