NSX-T agents on Transport Node

One of the frequently asked questions in an NSX-T class is that what is the functionality of the NSX-T agents on Transport nodes. When the hypervisor hosts are configured as Transport Nodes, the following list of NSX-T agents are installed on Hypervisor hosts and NSX Edge nodes. Each NSX-T agent performs a specific functionality on Hypervisor hosts and NSX Edges. The following table lists those NSX-T Agents and the role of each agent on the Transport Nodes. You will find these services/Agents in the /etc/init.d/ the directory in the root privileged mode.
