**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser):  
Opensearch v2.12.0  
Data prepper v.2.6.2

**Describe the issue** :  
I’m trying to figure out how to configure data prepper on a kubernetes cluster to receive OTEL events over HTTP/HTTPS.

For this use case, I have a data prepper instance running inside a gke cluster which is supposed to sink events to an opensearch cluster running inside this same cluster. This source is openTelemetry running on a different GCP project.

After reading some documentation ([https://opensearch.org/docs/latest/data-prepper/#source](https://opensearch.org/docs/latest/data-prepper/#source)), I’m assuming that I can somehow expose dataprepper to receive these events from openTelemetry.

I tried following this tutorial ([Demystify OpenTelemetry, with OpenSearch as a single plane of glass. | by Erik Åström | Medium](https://medium.com/@erikstrm_11611/demystify-opentelemetry-with-opensearch-as-a-single-plane-of-glass-919f884eb568)) but after deploying data-prepper with a service.yaml similar to the one appended in the doc, I noticed data-prepper wasn’t listening on every port I specified. It was only listening on 4900 and 21892 which I think were for API and Logs  
respectively.

I’m not sure where to send trace and metric events.

**Configuration** :  
I was hoping someone would share with me an example configuration for this use case or a similar one.

When you use the otel logs source, it by default listens on 21892 and by default has no path, so `/` is used. It’s a gRPC service.

[otel\_logs\_source - OpenSearch Documentation](https://opensearch.org/docs/latest/data-prepper/pipelines/configuration/sources/otel-logs-source/) is the more complete link to follow to configure the otel logs source.
