Netconf - How to get Interface Statistics?

[NetDevOp]

I can't seem to get interface statistics from IOS XR devices... I've tried a few different filters but the only result is null.

A similar method to get NTP status works.

Here is the python code:

from ncclient import manager
import xmltodict
import json

ncm = manager.connect(host='10.10.10.1', port=830, username='cisco',
password='cisco123', device_params={'name': 'iosxr'}, timeout=100)



print(ncm.connected)



vf = """

<filter type="subtree">
<interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces">
<interfaces-state>
</interfaces-state>
</interfaces>
</filter>"""


software_data = ncm.get(vf)

software_json = xmltodict.parse(str(software_data))

print(json.dumps(software_json['rpc-reply'], indent=2))

I've also tried filters using ifoper-mgr, like this:

vf = """
<filter type="subtree">
 <ifmgr-oper xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ifmgr-oper">
  <interface-properties> 
   <data-nodes/>
  </interface-properties>
 </ifmgr-oper>
</filter>
"""

Hello @NetDevOp,

I want to make sure you're aware of the following free resource on DevNet:

• IOS XR Programmability Sandbox

• IOS XR Always-On Sandbox

With these IOS XR Sandboxes, you can 'test drive APIs at every layer of the IOS XR network stack from model-driven YANG manageability APIs and ZTP hooks for CLI automation to highly performant Service-Layer APIs at the infrastructure layer – all just a click away. This sandbox provides access to two IOS XRv9000 instances along with a development environment (devbox) to install and utilize tools of your choice to interact with IOS XR.'
