NetworkMonitoring

Python Code that allows Network Engineers to apply use-cases exploring Network Observability, Assurance and Automation to enhance Network Monitoring

Overview

Python Code that allows Network Engineers to enhance monitoring capability by targeting specific triggers within the network infrastructure.

Use Case Description

This use case is particularly helpful in validating network observability & assurance by utilizing defined triggers. PYATS's modular methods with parsing makes it incredibly easy to extract the specific information required. (In this case route presence within the table).

Python

The script is written in python using PYATS to interact with the active devices, a GENIE model API to extract the state of a route within the routing table, and store the results in a json file.

Output: The results of the state is stored in a json file. This can also be enhanced to execute follow up actions such as shutdown an interface, etc.

Prerequisites

Python3.6 and above

Toolbox

Main.py: includes the main script run which contains relevant code to connect to the devices highlighted in the testbed file and returns the outcome as a json file.

Gene.yml: this is the PYATS testbed file that contains the device/devices that would be connected to.

You can test this on Cisco's DevNet Sandbox Labs/IOS XE on CSR Latest Code - AlwaysOn/IOS XE on CSR Latest Code AlwaysOn1

Step 1 - Downloading - Option A Using a Docker Image

Download and setup docker suitable for your Operating System
https://docs.docker.com/get-docker/
Download the latest version of the PYATS from docker hub

$ docker pull ciscotestautomation/pyats:latest

Run the docker image

$ docker run -it ciscotestautomation/pyats:latest /bin/bash

Step 1 - Downloading - Option B Using GIT

Clone the repository

git clone https://github.com/yzmar4real/networkmonitoring.git

CD into the directory

cd networkmonitoring

(Optional) Use the directory as a virtual environment for the project

python3 -m venv .

(Optional) Start the virtual environment and install the requirements for the project

source bin/activate

Step 2 - Defining the Testbed for devices to be audited

Edit genie.yml file to include parameters for your devices. It is usually advisable to target the device with the most outbound interface.

Step 3 - Executing the Script

Execute the main script from console

python3 Main.py
