Tracing fields
Elastic Cloud Serverless projects are autoscaled environments, fully managed by Elastic and available on Elastic Cloud. Availability This functionality is generally available and ready for production usage. Serverless interfaces and procedures might differ from classic Elastic Stack deployments. The Elastic Stack includes Elastic's core products such as Elasticsearch, Kibana, Logstash, and Beats. Availability This functionality is generally available and ready for production usage. Unless stated otherwise on the page, this functionality is available when your Elastic Stack is deployed on Elastic Cloud Hosted, Elastic Cloud Enterprise, Elastic Cloud on Kubernetes, and self-managed environments. This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes.

Distributed tracing makes it possible to analyze performance throughout a microservice architecture all in one view. This is accomplished by tracing all of the requests - from the initial web request in the front-end service - to queries made through multiple back-end services.
Unlike most field sets in ECS, the tracing fields are not nested under the field set name. In other words, the correct field name is trace.id, not tracing.trace.id, and so on.
| Field | Description | Level |
|---|---|---|
| span.id | Unique identifier of the span within the scope of its trace. A span represents an operation within a transaction, such as a request to another service, or a database query. type: keyword example: 3ff9a8981b7ccd5a  span_id |

| trace.id | Unique identifier of the trace. A trace groups multiple events like transactions that belong together. For example, a user request handled by multiple inter-connected services. type: keyword example: 4bf92f3577b34da6a3ce929d0e0e4736 trace_id |
extended |
| transaction.id | Unique identifier of the transaction within the scope of its trace. A transaction is the highest level of work measured within a service, such as a request to a server. type: keyword example: 00f067aa0ba902b7  Not applicable. |
