Greengrass currently only supports uploading logs from Greengrass system and Lambdas to CloudWatch Logs.
In your case, your application runs on a device which connects to Greengrass. You may directly use CloudWatch/S3 SDK in your application to upload logs. Or you can publish you application logs to an MQTT topic, and deploy a Lambda to listen on the topic and directly write to Lambda logs.
Hope this answers your question.
