How to include a health-check endpoint in a Azure Machine Learning Model deployed as an AKS Webservice? - azure-machine-learning-service

Question

When we deploy a model using Azure Machine Learning Service, we need a scoring script with at least two functions init which is run once when a model is first deployed and a run function which is run against any data we want to be scored.
The endpoint for this is: http://<IP-Address>/api/v1/service/<Webservice-Name>/score
Is there a way to include a health-check function in the deployed web service? Maybe adding another function healthcheck() and a corresponding endpoint http://<IP-Address>/api/v1/service/<Webservice-Name>/health which when pinged sends us a custom JSON containing information about the health of our service. This may even include information about the Azure Health Check too:

Apparently, the Azure Machine Learning SDK has to show the properties of the class Webservice. I haven't found any mention to this issue online.
To reproduce fully the experiment, you have to install AML SDK:
pip install azureml-core
And get the workspace:
# get the workspace
subscription_id = '<your_subscription_id>'
resource_group = '<your_resource_group>'
workspace_name = '<your_workspace_name>'
ws = Workspace(subscription_id, resource_group, workspace_name)
Using the Webservice Class, it should work. I have 3 services, but I can't see the status:
# this should work, but it isn't returning the state
for service in Webservice.list(workspace= ws):
print('Service Name: {} - {}'.format(service.name, service.state))
>> Service Name: akstest - None
>> Service Name: regression-model-1 - None
>> Service Name: xgboost-classification-1 - None
Using an intermediate step using the _get() method, it works:
# this works
for service in Webservice.list(workspace= ws):
service_properties = Webservice._get(workspace= ws, name = service.name)
print('Service Name: {} - {}'.format(service_properties['name'], service_properties['state']))
>> Service Name: akstest - Failed
>> Service Name: regression-model-1 - Healthy
>> Service Name: xgboost-classification-1 - Healthy
