Viewing the Health and Status of a Role Instance
You can view the health and status of a role instance by clicking the role instance under the Role Counts column.
If there is just one instance of this role, this opens the Status tab for the role instance.
If there are multiple instances of a role, clicking the role link under Role Counts will open the Instances tab for the service, showing instances of the role type you have selected.
If you are viewing a point in time in the past, the Role Count links will be greyed out, but still functional. Their behavior will depend on whether historical data is available for the role instance.
