'Horovod Timeline and MPI Tracing in Azure Machine Learning Workspace(MPI Configuration)

All,
I am trying to train a distributed model using Horovod on Azure Machine Learning Service as shown below.

estimator = TensorFlow(source_directory=script_folder,
                       entry_script='train_script.py',
                       script_params=script_params,
                       compute_target=compute_target_gpu_4,
                       conda_packages=['scikit-learn'],                       
                       node_count=2,                        
                       distributed_training=MpiConfiguration(),
                       framework_version = '1.13',
                       use_gpu=True
                      )
run = exp.submit(estimator)

How to enable Horovod timeline?
How to enable more detailed MPI tracing to see the communication between the nodes?

Thanks.

The following uses the Tensorflow Estimator class in the SDK, that distributed_training is set to Mpi().
