This view (popup) can be accessed by clicking on ‘Health’ hyperlink on any of the topology visualization screens.
This view shows health of different services as defined by their accessibility from DCNM. These services include POAP (Power on Auto Provisioning), XCP (Extensible Communications Platform) service, LDAP (Lightweight Directory Access Protocol) service, etc., and the orchestrator which in turn is connected to different vCDs.
The node color is either green, which means the service is up and running and is accessible to DCNM, or red, which mean the service is down and cannot be accessed.
