ANX-a tool to test telemetry

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。

https://github.com/cisco-ie/anx

安装

[root@xuxing239 ~]# git clone https://github.com/cisco-ie/anx
[root@xuxing239 ~]# cd anx/
[root@xuxing239 anx]# docker build -t netconf-explorer .
[root@xuxing239 anx]# docker run --name netconf-exlorer -d -p 9269:8080 netconf-explorer
[root@xuxing239 anx]# docker ps
CONTAINER ID   IMAGE              COMMAND                  CREATED      STATUS      PORTS                    NAMES
34cd21044420   netconf-explorer   "/usr/share/jetty9/b…"   3 days ago   Up 3 days   0.0.0.0:9269->8080/tcp   netconf-exlorer
[root@xuxing239 anx]# 

安装完成后浏览器访问server的9269端口即可。

连接设备

这里使用IOS XR设备做演示, 首先IOS XR设备上需要配置相应的ssh netconf 配置, 使用ssh 用户名密码登录IOS XR设备。

NCS5501:
ssh server v2
ssh server netconf vrf default
RP/0/RP0/CPU0:R2-5501#show run netconf-yang agent 
Thu Oct 31 04:24:33.798 UTC
netconf-yang agent
 ssh
RP/0/RP0/CPU0:R2-5501#show run netconf 
Thu Oct 31 04:24:22.880 UTC
netconf agent tty

如何快速获得sensor path

如下, 采取关键字搜索:

如何快速的get到该sensor path下的数据呢,我们需要使用NETCONF console的工具:

Telemetry其他测试

Telemetry分为两种模式Dial-Out/Dial-In, 之前文章 Telemetry simple configuration in Cisco XR devices 介绍了Dial-Out的模式, 设备按一定的频率pull 数据到server, 以下是一个Dial-in的配置案例:(server只去订阅自己感兴趣的数据)

RP/0/RP0/CPU0:NCS5516-B#show run telemetry model-driven 
telemetry model-driven
 sensor-group cpu
  sensor-path Cisco-IOS-XR-wdsysmon-fd-oper:system-monitoring/cpu-utilization
 !
RP/0/RP0/CPU0:NCS5516-B#show run grpc 
grpc
 port 57999
 no-tls
!

当你订阅cpu相关信息后, ANX会自动往路由推送如下配置, 该配置会在你关闭采集窗口后自动remove掉。
