About The Project

Serstat is a scalable, real-time monitoring application for collecting and displaying resource information of many servers in a network.

Built With

• Node.js as the primary framework and for the cluster module.
• React.js for the real-time dashboard.
• Express.js for the backend api.
• MongoDB for the storage of metrics in timeseries collections.
• Socket.io for websockets.
• Redis adapter for socketio.

⚠️⚠️⚠️ This project was created for learning purposes and the code is untested. In the current state, this is not a good option for production usage. ⚠️⚠️⚠️ Check OpenWISP or Netdata for production use.

Features

On its own, serstat has a react based dashboard for displaying real-time information. However, since the data can be stored in a mongodb collection, one could leverage mongo's features for creating charts as explained later.

React Dashboard

A react dashboard which displays metrics in real time.

MongoDB Timeseries Collections

The metrics are by default, stored in a mongoDB collection which can be used for creating charts as explained in the mongodb charts guide. In future, the react dashboard may possibly display this information itself.

Architecture

The application comprises of 3 components:

• React Dashboard
• Agent Script
• SocketIO Server

The socketIO server is responsible for creating node cluster for concurrent processing when a large number of servers are sending their data simultaneously. By default, the socketio server will update the dashboard on an interval of 1000ms which can be configured as per the user's needs.

Usage

First, clone this repository on your host machine.

Installing the dashboard

First, install the socketio server using the following commands:

$ cd server
$ npm i
$ npm start

Make sure to copy the .env_sample file into .env and set up the environment variables accordingly

Install and start the react dashboard using the following commands:

$ cd client
$ npm i
$ npm start

Again, make sure to copy the .env_sample file into .env and set up the environment variables accordingly

Connecting devices

For every device in the system, you have to run an agent on it. To install and start an agent, use the following commands:

$ cd agent
$ npm i
$ npm start

Make sure to set up the environment variables in the .env file accordingly

Mongodb charts

With your provided credentials, a mongodb timeseries collection will be created. Follow the mongodb charts guide for instructions on setting up charts for your choice of metrics.
