Currently I am working on a project to collect port traffic data from a few network devices. These are the interesting areas of that project

• .env file to store credentials.
• Read port data from a csv file and store in a list.
• SSH to the devices and collect traffic data from devices using netmiko library in Python.
• Resolving errors that occur during traffic collection.
• Usage of else in exception handling.
• Implement a retry mechanism to run when traffic fetching fails.
• Extract the data from netmiko result using regular expressions and store in Python data structures. Used regex capture groups for extracting the required data.
• Convert traffic utilisation to traffic rate by using port type.
• Calculate total traffic of ports.
• Write results to csv files.
• import a function from a parent directory.
• In version 2.0 rewrote the project to use Python classes.
• Writing utility functions in a file named util.py

Functionalities that planned to be implemented

• add tabulate for printing output on commandline
• add option parsing using argparser.
• database implementation
• cache implementation
• charting
