Make sure to first read the README in the repo which will build the lab environment before proceeding.

``console git clone https://github.com/burnyd/Openconfig-Lab/ && cd OpenConfig-Lab source startup.sh


# Google gnxi python grpc interface

[Google GNXI project](https://github.com/google/gnxi)

The Google python gnmi interface is quite nice for anyone who knows python.  This will allow for python to use a Google protobuf file which is located in the scripts directory.

To test to make sure that the gnmi client is working properly the test simply sends a grpc stream to ceos1 and pulls back the path for interface counters of Ethernet1.

```console
sh-3.2# docker exec -it mgt1 bash
root@b6efac7b7b0f:/# cd /tmp/scripts/
root@b6efac7b7b0f:/tmp/scripts# python gnmitest.py
{
  "openconfig-interfaces:in-octets": "2363",
  "openconfig-interfaces:in-errors": "0",
  "openconfig-interfaces:in-multicast-pkts": "15",
  "openconfig-interfaces:out-octets": "15315",
  "openconfig-interfaces:in-broadcast-pkts": "28",
  "openconfig-interfaces:out-multicast-pkts": "115",
  "openconfig-interfaces:in-unicast-pkts": "0",
  "openconfig-interfaces:out-unicast-pkts": "0",
  "openconfig-interfaces:out-broadcast-pkts": "5",
  "openconfig-interfaces:out-discards": "0",
  "openconfig-interfaces:out-errors": "0",
  "openconfig-interfaces:in-discards": "0"
}

The gnmicli from the actual google repo will take arguments for the CLI so lets check the bgp path for example of ceos2.

sh-3.2# docker exec -it mgt1 bash
root@b6efac7b7b0f:/# cd /tmp/scripts/
root@b6efac7b7b0f:/tmp/scripts# python gnmicli.py -n -m get -t ceos2 -p 6030 -user admin -pass admin -x /network-instances/network-instance[name=default]/protocols/protocol[name=BGP][identifier=BGP]

{
  "openconfig-network-instance:name": "BGP",
  "openconfig-network-instance:isis": {
    "global": {

Now that we know this is working lets go ahead and kick off the streaming client

root@b6efac7b7b0f:/tmp/scripts# python subscribe.py --host ceos1 --port 6030 --username admin --password admin --subscribe "interfaces/interface[name=Ethernet1]/state/counters"
INFO:test-client:start to subscrib path: interfaces/interface[name=Ethernet1]/state/counters in stream mode
[name: "interfaces"
, name: "interface"
key {
  key: "name"
  value: "Ethernet1"
}
, name: "state"
, name: "counters"
]
Inserted interfaces.interface[name=Ethernet1].state.counters.in-broadcast-pkts using value 88

Inserted interfaces.interface[name=Ethernet1].state.counters.in-discards using value 0

Inserted interfaces.interface[name=Ethernet1].state.counters.in-errors using value 0

This python file will simply insert data into the kafka stream it will then be inserted from the consumer of it which is telegraf and inserted into grafana

Log into Grafana

Open up your browser and try http://127.0.0.1:3000

username: admin
password: admin

Click on the add source button.

server is influx database is OC username / password are dan/dan

Graph Source

Once this is finished select a new graph.

Grafana is nice because it will tab complete for all units that are within Influx.

Eth1

Select the following just like the output above and this should give exactly that.
