-### Metrics
-
-The value of the environment variable `OTEL_SEMCONV_STABILITY_OPT_IN` (a comma-separated list of values) will define which metrics are being collected.
-Possible values:
-
-- `database` - emit the new database conventions and stop emitting old database conventions.
-- `database/dup` - emit both the old and the stable database conventions, allowing for a seamless transition.
-- The default behavior (in the absence of one of these values) is to continue emitting only the old database conventions.
-
-List of Metrics affected by this environment variable (if the metric is not listed here, it will always be emitted):
-
-| Metric                                  | Emitted with value of `OTEL_SEMCONV_STABILITY_OPT_IN` |
-| --------------------------------------- | ---------------------------- |
-| `db.client.operation.duration`          | `database` or `database/dup` |
-| `db.client.connection.count`            | `database` or `database/dup` |
-| `db.client.connection.pending_requests` | `database` or `database/dup` |
