vSphere App HA requires vCenter Hyperic agents to be installed on each virtual machine that you want to monitor.

To enable integration between vCenter Hyperic and vSphere App HA, you must install the vCenter Hyperic server and deploy a vCenter Hyperic agent on all of the virtual machines that vSphere App HA must monitor.

To install the vCenter Hyperic server and vCenter Hyperic agents, see Getting Started with vCenter Hyperic at https://www.vmware.com/support/pubs/vfabric-hyperic.html.
