What would my XML Node be?

I am trying to add an HTTP XML/REST for Palo Alto Firewall. I followed the steps described in this KB article:

• How to Monitor Palo Alto Firewall through XML API However, I am not sure what my XML Node is. I tried ethernet1/1, throughput, default-group

<response cmd="status" status="success">
<result>
QoS throughput for interface ethernet1/1, node default-group (Qid 0):
class 4:    11018 kbps
</result>
</response>

api http-xml palo-alto-networks
