This is prototype to demonstrate the potential solution for Carsales monitoring solution.

The system contains below components

1. AdminClient
2. MonitoringWebApi
3. PollingService

1. AdminClient

Client configured to run on http://localhost:53659/ that calls fetches data from the webapi. The http endpoints are hardcoded to get historical data between 2018-01-01 to 2020-01-01 ( from database ) and the latest messagecount from rabbitmq

2. MonitoringWebApi

Simple webapi configured to run on http://localhost:60634/ that returns

a. Live message count directly from rabbitmq

b. Historical information ( top 10 order by createddate desc ) from database

3. PollingService

Simple windows service configured to run every x minutes. The service polls number of messages at given point of time and updates database.

a. Setup a new database 'Carsales' on MSSQL and run below script to create QueueHistory table USE [Carsales] GO

CREATE TABLE [dbo].[QueueHistory]( [MessageCount] [int] NULL, [QueueName] varchar NULL, [CreatedAt] [datetime] NULL ) ON [PRIMARY]

GO

b. Ensure an exchange 'TestExchange' and 'Queue' is created and publish messages

c. Download the code

d. Open MonitoringSolution.sln in VS 2017

e. Ensure that values in the config are correct ( Connectionstring to database, rabbitmq details, exchange and queuenames, etc ) for the MonitoringWebi and PollingService

f. Run the solution

1. No logging, auditing and few hardcodings at the client values are done since this is a prototype

2. To bypass CORS issue, the webapi has below value hard coded in order to accept request from the client that runs on localhost:53659

[EnableCors(origins: "http://localhost:53659", headers: "", methods: "")]

3. Notification Service is not implemented.
