Connectivity (VMware) service

The Connectivity (VMware) service monitors the availability of the TCP ports for the CIM-XML and WS-Management protocols on an ESXi server or vCenter appliance. These are the protocols N-able N-central uses to monitor virtualized environments that are running on VMware hosts. This service provides a way to determine if there will be any issues discovering and monitoring those environments.

The default CIM-XML port is 5989, and the default WS-Management port is 443. If you configured ESXi server or vCenter appliance to use custom port assignments, N-able N-central can make the appropriate modifications by clicking Settings > Monitoring Options of the device.

N-able N-central uses the CIM services and ports for monitoring.
