Monitoring and Debugging Using AWS CloudWatch

Amazon provides us many useful services but here we will be discussing its one of the services known as CloudWatch. This service is provided for monitoring AWS resources and applications which we run on AWS. This monitoring tool makes easy for us to easily monitor our application using generated CloudWatch logs and hence help to elucidate data.

Why Use AWS CloudWatch?

1- To collect and track metrics.

2- To collect and monitor log files i.e. recording all events occurring in your application on AWS.

3- To set an alarm that can be set for any threshold i.e. if any resource exceeds that threshold, it will send notification and even automatically take some reactive action against it.

Here AWS resource includes Amazon EC2, instances, Amazon DynamoDB tables, Amazon RDS DB instances as well as custom metrics generated by your application and services.

CloudWatch allows us to track a wide variety of useful metrics for your application:-

1- Resource Utilization

2- Application’s Performance

3- Network Traffic.

4- Memory Utilization

5- Storage space available

6- Operational health

All of the above metrics can be monitored on CloudWatch using following ways:-

1- Amazon CloudWatch Console.

2- AWS CLI

3- CloudWatch API.

4- AWS SDKs

You can use any of the ways to access CloudWatch. Here we will be discussing the Amazon CloudWatch Console.

How To Use CloudWatch?

This shows all of the metrics provided by CloudWatch at a glance which allows us to view the system’s performance.

Now we can jump to particular metrics. For example invocation graph which shows the number of hits to the lambda function

Amazon CloudWatch provides us the functionality of creating alarms so that it send us notification whenever any metrics reach the threshold point. For example:- it will send alarm

It provides us another option of monitoring application and AWS resource using log data. CloudWatch logs can also be used for tracking the number of errors and it sends a notification whenever the rate of error exceeds the threshold point. Monitoring can be used to detect many times of error such as NullPointerException, NumberFormattingException, etc. Or to monitor the flow of your application.

This is how AWS CloudWatch can be used for Monitoring and hence Debugging.
