 You don't need to run an OTEL collector to use this feature. Events are delivered directly to your S3 bucket where you can:
 
 - Query them directly using Athena, BigQuery, or similar tools
 - Ingest into your data lake (Snowflake, Databricks, etc.)
 - Forward to any OTEL-compatible backend for visualization and alerting
 
 <Note>Enterprise customers can enable PII redaction to automatically protect sensitive information in logs. Contact your Account Manager to learn more.</Note>

+**`conversation_deleted`** - Emitted when an agent conversation is permanently deleted, either individually or as part of a bulk deletion. Each deleted conversation produces a separate event.

+**`workforce_task_deleted`** - Emitted when a workforce task is deleted, once per task (a bulk delete emits one event per task). Fires for deletions from the Workforce UI, deletions from the chat interface, and deletions performed by automated data retention policies. A workforce task is a single run of a workforce, which is distinct from an agent conversation.

 **Attribute**: `gen_ai.tool.definitions`
 
 <Warning>`gen_ai.tool.definitions` was previously an array type (`arrayValue`). It is now a JSON string (`stringValue`). If you consume this field in your pipeline or queries, you need to call `JSON.parse()` on the value to work with the tool definitions as structured data. The content is identical - the same tool definitions are present, just serialized as a string for better compatibility across OTEL exporters and backends.</Warning>
