Monitoring-terminal-dash

MVP implementation of a monitoring tools using NodeJs based on Terminal capabilities for visualization and interaction.

Getting Started

This project is fully written in JS it's mandatory to use NodeJS for execution

Prerequisites

npm install

Start

To launch the project use the following command

npm start

1. Add website and services to monitor
2. Start

Hints:

• to navigate in dashboard use tab to switch between Tables, and arrows for list

Mocked services

To start the monitor on predefined values and localhost servers run:
[:warning: ports number(3000,3200,3400,3500) should be free]

npm run-script example 

Test

I created an End To End test by creating mocked services that turn on and off randomly to generate alerts you can execute it by calling :
[:warning: ports number(3000,3200,3400,3500) should be free]

npm test

Improve

I can Improve this application design by adding the following:

• Alert using emails, slack ...
• Create client version to monitor inside metrics such as (CPU, RAM, Traffic, ...)

But this architecture is not scalable because it's monolithic monitor one of the improvements that I thought of is creating a distributed monitoring system using :

• Watcher services
• Realtime processing using (Brokers, Kafka...)
• Big data storage
• Client services

Technology Choice

I choosed NodeJs for multiple reasons such as dynamic language, fast prototyping, non-blocking. A monitoring tools is very concurrent application so JS is good fit for fast implementation with caution of a whole non-blocking system(DB-writing/reading, Async...) which can cause some harm with all the benefits that comes with.
