The `service_map_stateful` processor uses OpenTelemetry data to create a distributed service map for visualization in OpenSearch Dashboards. The following table describes the option you can use to configure the `service_map_stateful` processor.
window_duration | No | Integer | Represents the fixed time window, in seconds, during which service map relationships are evaluated. Default value is 180.
The following table describes common [Abstract processor](https://github.com/opensearch-project/data-prepper/blob/main/data-prepper-api/src/main/java/org/opensearch/dataprepper/model/processor/AbstractProcessor.java) metrics.
| Metric name | Type | Description |

| `recordsIn` | Counter | Metric representing the ingress of records to a pipeline component. |
| `recordsOut` | Counter | Metric representing the egress of records from a pipeline component. |
| `timeElapsed` | Timer | Metric representing the time elapsed during execution of a pipeline component. |
The `service-map-stateful` processor includes following custom metrics:
