How to Integrate Python flask with Amazon Cloud Watch

Flask is an open-source web application framework for Python. This blog walks you through the process of generating a Flask application and deploying it to an AWS Elastic Beanstalk environment. Flask is awesome; it’s the easiest way to learn web development start with small, and then you can quickly add any upgrades you need — email, databases, forms, also Amazon Web Services is fantastic and none are more flexible than AWS.

Watchtower is a log handler for Amazon Web Services Cloud Watch Logs. Cloud Watch Logs is a log management service built into AWS. It is conceptually similar to services like Splunk and Loggly, but is more lightweight, cheaper, and tightly integrated with the rest of AWS.

Objective
The main objective of this project is that we will be able to generate log files and it will automatically appear in our Cloud watch and provides real-time monitoring

Solution:
Note: In this document, we explain step by step Implementation between the flask and Cloud watch (To store logs).

Step1 :

pip install watchtower

Step2:

Pip install aws CLI

This will install the aws-CLI package as well as all dependencies.
The quickest way to get started is to run the aws configure command:

Step3: Go to your flask project directory and run the following command to connect to aws cloud watch

$ AWS configure

AWS Access Key ID: your AWS access key

AWS Secret Access Key: your AWS secret key

Default region name [us-west-2]: your AWS region

Default output format [None]: JSON

Step4: Go to your main.py file and write the following code.
