+## Configurable service map limits
+Introduced 3.2  
+{: .label .label-purple }
+
+OpenSearch provides default limits for service map rendering. You can increase these limits to render large topologies more completely or lower them to improve client-side performance when focusing on smaller views. This is especially important in environments with many services or dense interconnections, for which the default limits may result in incomplete maps.
+
+
+### Service map configuration settings
+
+Two **Advanced Settings** control the size and complexity of service maps generated by service map queries:
+
+- `observability:traceAnalyticsServiceMapMaxNodes`: The maximum number of service nodes displayed. Default is 500. 
+- `observability:traceAnalyticsServiceMapMaxEdges`: The maximum number of edges (service-to-service connections) displayed. Default is 1,000.
+
+To configure these settings in OpenSearch Dashboards, follow these steps:
+1. From the main menu, select **Management** > **Dashboard Management** > **Advanced Settings**.
+1. In the search box, search for `Observability`. In the **Observability** section, locate the **Trace analytics service map maximum edges** and *Trace analytics service map maximum nodes** settings. Adjust the values according to your environment and performance requirements, then save your changes. Higher values can increase browser memory and CPU usage.
