Intro

This project is my work for the website availability and performance monitoring provided by Datadog You can find :

• Complete project code in Java
• A pdf detailing the choices I made and the architecture of the project
• A .jar file that launch the application in the console

Requirements

To run this project, you must have a recent version of:

• Java
• MySQL

Further more, the project has been throughly tested on Mac-os only, but should work on Linux.

Configuration

You need to configure the database as follow :

• Create the Database

CREATE DATABASE bdd_monitoring DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

• Create the user

CREATE USER 'gabrielle'@'localhost' IDENTIFIED BY 'olivia';

• Give the priviledges to the user

GRANT ALL ON bdd_monitoring.* TO 'gabrielle'@'localhost' IDENTIFIED BY 'olivia';
FLUSH PRIVILEGES;

• Create the databse for Website :

CREATE TABLE  bdd_monitoring.Website(
 idWebsite INT( 11 ) NOT NULL AUTO_INCREMENT ,
 url VARCHAR( 255 ) NOT NULL ,
checkInterval INT( 11 ) NOT NULL ,
 date DATETIME NOT NULL ,
 PRIMARY KEY ( idWebsite ),
 UNIQUE ( url )
) ENGINE = INNODB;

• Create the database for the Checks :

CREATE TABLE  bdd_monitoring.CheckWebsite(
idCheck INT( 11 ) NOT NULL AUTO_INCREMENT ,
httpStatusCode INT( 11 ) NOT NULL ,
responseTime BIGINT( 20 ) NOT NULL ,
idWebsite INT( 11 ) NOT NULL ,
date DATETIME NOT NULL ,
PRIMARY KEY ( idCheck)
) ENGINE = INNODB;

Usage

The user can type different commands in the console application :

• runMonitoring <> : run the monitoring
• addWebsite <url, checkInterval> : add a website to the database
• deleteWebsite : delete a website from the database
• updateCheckInterval <url, checkInterval> : update checkInterval of a website
• allWebsite <> : print all websites in the database
• help <> : print all the available commands

When the user run the monitoring, a graph user interface appears.
