I don't think milvus supports running on Windows. do you mean you running on Windows docker? Please refer this doc to export the whole Milvus logs for investigation. For Milvus installed with docker-compose, you can use docker-compose logs > milvus.log to export the logs.

@yanliang567 My Milvus is installed on Kubernetes and proxied to the local machine via a proxy method. This set of old APIs can be tested locally on Windows, but some functions are not supported.

final MilvusServiceClient milvusClient = new MilvusServiceClient( ConnectParam.newBuilder() .withHost("127.0.0.1") .withPort(19530) .withToken("root:Milvus") .withDatabaseName(dataBaseName) .build() );

    DescribeCollectionParam describeCollectionReq = DescribeCollectionParam.newBuilder()
            .withCollectionName("meta_collection1")
            .build();

    R<DescribeCollectionResponse> describeCollectionRes = milvusClient.describeCollection(describeCollectionReq);

    System.out.println(describeCollectionRes)

@davewxt are you able to ping the milvus end point? We want to make sure there is no network issue here.

could you connect with attu and check if milvus service is all start as expected? or you can offer some log from server side
