Basic verification of a DaaS installation includes connecting to the following web pages (both through a load balancer, if applicable, and directly to each node): Desktop Portal, Administration Console, and Service Center.
Port Response - In addition to using ping, monitoring software can check response of specific ports - that is, if they respond to an "open socket" request. DNS and DHCP are exceptions which use UDP, and may require more intelligent monitoring.
Monitoring CIM Classes - DaaS management nodes run a variety of CIM classes that provide information about system operation. See CIM Providers on DaaS Management Nodes below for more details.
