 ## Observability with Logfire
 
-When using [Pydantic Logfire](../logfire.md), we **recommend disabling DBOS's built-in OpenTelemetry tracing**.
-DBOS automatically wraps workflow and step execution in spans, while Pydantic AI and Logfire already emit spans for the same function calls, model requests, and tool invocations. Without disabling DBOS tracing, these operations may appear twice in your trace tree.
+DBOS automatically generates OpenTelemetry spans for each workflow and step execution, and Pydantic AI emits spans for each agent run, model request, and tool invocation. You can send these spans to [Pydantic Logfire](../logfire.md) to get a full, end-to-end view of what's happening in your application.
 
-To disable DBOS traces and logs, you can set `disable_otlp=True` in `DBOSConfig`. For example:
-
-
-```python {title="dbos_no_traces.py" test="skip"}
-from dbos import DBOS, DBOSConfig
-
-dbos_config: DBOSConfig = {
-    'name': 'pydantic_dbos_agent',
-    'system_database_url': 'sqlite:///dbostest.sqlite',
-    'disable_otlp': True  # (1)!
-}
-DBOS(config=dbos_config)
-```
-
-1. If `True`, disables OpenTelemetry tracing and logging for DBOS. Default is `False`.
+For more information about DBOS logging and tracing, please see the [DBOS docs](https://docs.dbos.dev/python/tutorials/logging-and-tracing) for details.
