> [!NOTE] > > - v0.10.0 adopts the OpenTelemetry semantic convention names > `rpc.client.call.duration` and `rpc.server.call.duration`. The corresponding > Prometheus metric names include `_call_` as shown in the table. > - Starting with v0.12.1, server-side Redis and Memcached measurements use > `db.server.operation.duration` instead of `db.client.operation.duration`. > Update dashboards and alerts that query those server-side measurements. OBI can also export [Span metrics](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/connector/spanmetricsconnector) and [Service graph metrics](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/connector/servicegraphconnector), which you can enable via the [features](../configure/options/) configuration option. ## Attributes of OBI metrics For the sake of brevity, the metrics and attributes in this list use the OTel `dot.notation`. When using the Prometheus exporter, the metrics use `underscore_notation`. In order to configure which attributes to show or which attributes to hide, check the `attributes`->`select` section in the [configuration documentation](../configure/options/). | Metrics | Name |
