AMS and CMS service will handle a lot of requests when user leave the cluster detail to be opened. It will cause high workload for our server. 

Maybe it's better to just request the corresponding API with current tab opened instead of request to all of the APIs.

For example, when I open cluster detail page Overview tab and refresh current tab, it will request endpoints like below which won't show on Overview tab. 

notification_contacts, support_cases, groups, ingresses, addons, identity_providers, aws_infrastructure_access_role_grants

Auto refresh will request the endpoints every minutes. Better to request the endpoint when corresponding tab is opened.
