OpenTelemetry Integration

Available on: Cloud Standard


You can export traces of your Hasura Cloud project to the OpenTelemetry compliant APM receiver. This can be configured on the Integrations tab on the project's setting page.


For Hasura Cloud projects, the OpenTelemetry Integration is only available on the Standard (pay-as-you-go) tier and above.


Currently, the OpenTelemetry Integration exports only traces. The support for metrics and logs will be added once the OpenTelemetry spec reaches stability.

Configure the OpenTelemetry integration

Navigate to the Integrations tab on the project settings page to find the OpenTelemetry integration.

Select OpenTelemetry Integration

The following config parameters are needed to set up the integration with the APM receiver:

  1. Endpoint

    OpenTelemetry compliant receiver endpoint. The URL scheme (http/https) determines if SSL(TLS) should be used for the communication. Your APM vendor will provide the OpenTelemetry Ingestion endpoint information. The appropriate endpoint for the chosen Connection Type should be used since the APM tools usually have different endpoints for HTTP and gRPC protocols.

  2. Connection Type

    Protocol to be used for the communication with the receiver. OpenTelemetry supports connections over gRPC and HTTP. The APM vendor documentation contains the protocols it supports for OpenTelemetry ingestion, and gRPC can be preferred if it supports both gRPC and HTTP.

  3. Batch Size

    Batch size is the maximum number of data points (spans in the context of traces) included in every export request made to the APM tool. The batch size should be an integer between 1 and 512.

  4. Headers

Headers are (optionally) added to every request made by Hasura to the APM receiver. APM vendors will provide Authorization/API keys with the required role/permissions to ingest OpenTelemetry data. Please refer to their documentation for the request header formats. Headers should be added here as a key:value pair.

  1. Attributes

    Attributes are (optional) custom tags added to the telemetry data. This is usually used to identify sources in a distributed tracing environment and aids in granular filtering and analytics.

  2. Export Telemetry Data

    Selects the telemetry data points to be exported. (Note: Currently only traces are supported).

After adding appropriate values in the OpenTelemetry Integration panel, click Connect Integration.

Configure OpenTelemetry Integration

Checking the status of the integration

The green/red dot signifies the status of the integration. The green dot indicates a successful export of the telemetry data to the APM receiver. Last Exported Traces is continuously updated, indicating the timestamp of the last telemetry data that was successfully exported. The orange dot reading Not exported yet means no requests have been made to the GraphQL API after configuring the integration.

OpenTelemetry Integration successfully configured

In case of errors while exporting telemetry data to the APM receiver, the dot becomes red and the error messages/instructions are displayed. Click the Update Settings button to update the config parameters.

View traces

Use your APM vendor's UI to to visualize and perform further analytics on trace data to monitor, diagnose and troubleshoot your application. Traces with their spans are listed out and selecting a trace shows a flame graph containing a visual representation of where the operation spent its execution time. For example, the image below shows a flame graph in Jaeger where a query took 5.64 milliseconds in total, of which 2.78 milliseconds was the actual Postgres database processing the query.

OpenTelemetry collector

OpenTelemetry provides a collector to export data to APM tools that do not support native OpenTelemetry ingestion. In such cases, this OpenTelemetry integration can be configured to send the data to the collector. Note: This collector should be run in your infrastructure and should be reachable by the Hasura backend, that is configured to send the data to the APM target. The list of supported exporter targets can be found in the OpenTelemetry Collector repository.
