[OpenSearch] Java Instrumentation not working when using OpenSearch-java with AwsSdk

[paulcerverayalvarez]

The instrumentation of opensearch in JAVA does not work with opensearch-java and the aws-sdk.

The current integration only covers opensearch-rest and opensearch-transport. When using a managed OpenSearch by AWS, we should use the openSearch-java according to the AWS Documentation which does not use the opensearch-rest or opensearch-transport implementation.

SdkHttpClient httpClient = ApacheHttpClient.builder().build();

OpenSearchClient client = new OpenSearchClient(
    new AwsSdk2Transport(
        httpClient,
        "search-...us-west-2.es.amazonaws.com", // OpenSearch endpoint, without https://
        "es",
        Region.US_WEST_2, // signing service region
        AwsSdk2TransportOptions.builder().build()
    )
);

InfoResponse info = client.info();
System.out.println(info.version().distribution() + ": " + info.version().number());

httpClient.close();
