Recommendation Action:

• As admin user, on the edge node, invoke the NSX CLI command 'get logical-router <service_router_id>' to identify the tier1 service-router vrf ID. 
• Switch to the vrf context by invoking 'vrf <vrf-id>' then invoke 'get high-availability status' to determine the service that is down.
