I am assuming you have TIG (Telegraf/Influx/Grafana) setup for general dashboard purposes. This is really simplle to setup and there are lots of blogs on this.

The script is going to call DNAC API via the newly released SDK.

I am going to assume a directory /opt/telegraf. If you want to install elsewhere you need to change the paths in the custom.conf file.

First (optional) step, create a vitualenv. This makes it less likely to clash with other python libraries in future. Once the virtualenv is created, need to activate it.

python3 -mvenv env3
source env3/bin/activate

Next clone the code.

git clone https://github.com/CiscoDevNet/DNAC-NOC.git

Then install the requirements (after upgrading pip). Older versions of pip may not install the requirements correctly.

pip install -U pip
pip install -r DNAC-NOC/requirements.txt

By default the script uses the devnet sandbox. If you want to change these you can edit the dnac_config.py file. You are able to either edit the defaults, or use environment variables if you are familiar with them.

Finallly, test the script.
Should see something like this.
You can edit the dnac_config.py file to change the DNAC you are connecting to. The default is a devnet sandbox.

$ ./DNAC-NOC/dnac_assurance.py 
{"Core.count": null, "totalcount": 14, "WIRELESS-client.count": 80, "WLC.count": null, 
"WIRED-client.count": 2, "AP.count": null, "WIRED-client.value": 100, "Access.count": null, 
"totalscore": 100, "WIRELESS-client.value": 25, "AP.score": 100, "Router.score": 100, 
"ALL-client.value": 27, "Router.count": null, 
"Access.score": 100, "Core.score": 100, "WLC.score": 100, "ALL-client.count": 82}

Now install the telegraf custom script, restart telegraf.

sudo cp DNAC-NOC/telegraf.d/custom.conf /etc/telegraf/telegraf.d/
sudo systemctl restart telegraf

log into grafana, select + create -> import

Select the jsonfile grafana/dashboard.json

Then add the dashboard

This will give you an empty dashboard.

Soon you wil see updated data
