NSX user world agents
NSX Manager is responsible for deploying the NSX Controller cluster, ESXi hosts preparation by pushing vSphere Installation Bundles (VIBs) to enable VXLAN, distributed routing, distributed firewall, and a user world agent used to communicate at the control-plane level. The functionality of the user world agent is highly critical and any failures will have a direct impact on the control plane learning, which eventually affects data plane traffic. So, let's discuss these agents, along with basic health checks and log locations.
netcpa
It is a user world agent that communicates with NSX control plane, and the netcpa service should be up and running on the NSX-prepared ESXi host. If the functionality is impacted, we will certainly experience routing and switching issues in the NSX environment, and the ESXi host won't learn new routes from the time the netcpa service was down. So, this is extremely important: creating the routes alone on an NSX Edge VM won't do the trick;...
