When clicking on "Add to Service..." on the "Integration | CI List" dashboard, selecting a service from the pop up window and click on "Add", nothing happen.
As long as there is no CI object in the list selected, it cannot be added to a service. "Add to Service..." does not mean a service will be added to the CI list. It means a CI object from the list will be added to a service.
A CI object will be created as soon as a SNMP trap has been send to Foglight.
