Site connectivity checker

Desktop application for checking site connection in a background mode by sending ICMP messages.

Problem and solution

Usually, when people need some site to interact with and it crashes, they update the page many times to check whether the site is available or not. Instead of this, we propose the desktop app which will ping the site every minute by sending ICMP messages in a background mode. When the site becomes available the app will send notification with site link to the user.

Prerequirements

• Python3
• Python libraries from requirements.txt

Getting started guide

1. From Site-connectivity-checker repository download all the documents to your local project
2. From the project directory write in command line/terminal pip install -r requirements.txt to install all the required libraries
3. From the project directory write in command line/terminal python3 ./main.py or python main.py to run the app

Glossary

How to use

1. After starting app execution you should add sites, which you often visit, to the checklist.
2. When some of these sites crashes start pinging it.
3. As soon as the site is available again the app will stop pinging it and send you notification with a link.
4. If the app is pinging the site, but you are not interested in this site anymore, just stop pinging.
5. You can also see the checklist of sites, add new sites and delete old ones whenever you want.
6. Stop app execution if there is no need in that.

Features

• add to add the site to checklist of sites
• delete to delete the site from checklist of sites
• on to start pinging the site untill it will be available
• off to stop pinging the site if you are not interested anymore in this site
• checklist to see the checklist of sites
• quit to stop the app

Architecture decisions

We decided to use observer pattern as it perfectly suits to our solution: an object (pinger) maintains dependent (user), called observer, and automatically notifies it about any changes (sites' availability) using special methods (sending notifications).
