This page provides a brief overview of the Observability API and the Telemetry (OTLP) API.
About the Observability API
The Observability API lets you do the following:
Configure the observability scope for your project. This scope controls which resources are searched by the explorer pages for log, metric, and trace data. For more information, see Configure observability scopes.
List information about the observability buckets in your Google Cloud project. Your trace data is stored in an observability bucket. For information about the data model, see Storage overview.
Create a link on a dataset, which lets BigQuery have read access to the dataset. To learn how to create a linked dataset, see Manage storage.
About the Telemetry API
The Telemetry (OTLP) API lets you send OTLP-formatted trace data to your project. This API provides compatibility and support for the open source OpenTelemetry ecosystem. Also, the limits for theTelemetry API are often more generous than for the Cloud Trace API. For more information, see the following documents:
