@EyalGonen this does not looks to be a SAS® Viya® on Microsoft Azure Marketplace Subscription because there is no way to stop and restart Viya on Microsoft Azure Marketplace Subscription and Users can start only an instance or delete an instance.
If the query is for the Viya environment which is installed/deployed on Kubernetes by you or your team, you can raise a support track/case to support@sas.com .
Having said that you need to monitor the pod status to check if all the pods are up and running to know if the Viya services are started or not, below are couple of approaches you can go with.
1. Check pod status:
kubectl get pods -o wide
2. Alternately Readiness service checks the status of the SAS Viya deployment to determine whether it is ready for use , below command can be used for the same: kubectl wait \ --for=condition=ready pod \ --selector="app.kubernetes.io/name=sas-readiness" \ --timeout=30s
0 = Ready, 1= Error
