Send logs from AWS Lambda to backend using opentelemetry collector

[anil-repos]

Hi
I am trying to send logs from AWS lambda (which is printed to stdout) to opensearch backend using opentelemetry collector.
My configuration looks like this :

1. I have central otel collector running inside vpc
2. I followed this documentation - https://opentelemetry.io/docs/faas/lambda-collector/

• 2a. I added otel collector lambda layer to my function from here -- https://github.com/open-telemetry/opentelemetry-lambda/releases
• 2b. I created custom otel collector config file at root of the project with following value :

 otlp:
   protocols:
     grpc:
       endpoint: '0.0.0.0:4317'
     http:
       endpoint: '0.0.0.0:4318'

exporters:
 debug:
   verbosity: detailed
 otlphttp:
   endpoint: http://<my-central-otelcol-endpoint>:4318/v1/logs
   tls:
     insecure: true

service:
 pipelines:
   logs:
     receivers:
       - otlp
     exporters:
       - otlphttp
 telemetry:
   metrics:
     address: localhost:8888

• 2c. I setup this env var in lambda -- OPENTELEMETRY_COLLECTOR_CONFIG_FILE = /var/task/collector.yaml

My question is - is it even possible to send logs directly from aws lambda to other place using opentelemetry collector.
Also, I do not want to use opentelemetry SDK and its logging APIs inside code.

Thanks,
