ANX(Advanced NETCONF Explorer) 是一个cisco开源软件, 发布如下github上,能帮助我们快速的查找一些sensor path, 做一些telemetry的实验, 具体的安装步骤可参考github主页。

安装

[root@xuxing239 ~]# git clone https://github.com/cisco-ie/anx
[root@xuxing239 ~]# cd anx/

Telemetry 是一种类似SNMP技术的feature,用于远程采集网络设备上相关信息。与SNMP不同的是,SNMP是Pull Mode,需要server端主动的要求Get某些信息,而Telemetry则是一种Push Mode,可以周期性、主动的push相关信息到server上。

如何获得相应的sensor-path

与SNMP的OID类似,sensor-path代表着你想要的获得哪些信息,在XR设备上我们可以使用如下命令去判断我们需要获得的信息是哪一类,即获得关键字;然后到yang文件夹过滤相关关键字:
