shutdown partially running vApps automaticly

Hi Folks

Within an particular organisation i have to automate the shutdown of all vApps

1. which are partially running and all VMs within the vAPP are Powered OFF or Suspended

2. count all running VMs within an entire ORG (many vCDs)

How can i realize this and how would be an API call using REST CLI script (using curl e.g.)?

For the action 2. i cannot see the posibility to call an vCD API call for VM state (running) can i realize this using VCD API or do i need access to vSphere API?

Thanks Dominik
