What is Cloudwatch in AWS?

In this article you will learn what is CloudWatch in AWS? and the detailed use of CloudWatch in AWS for your hosting and application development.

If you’ve already tried out some of the other services previously mentioned in this course, you may have even used CloudWatch without knowing it.

Amazon has integrated CloudWatch into most of the other AWS services for monitoring the activities and creating alarms.

In fact, those are the main two key functionalities of CloudWatch, monitoring resources and alerting you when some predefined criteria have occurred.

What is CloudWatch?

CloudWatch is broadly defined as a monitoring service for many different other services as well as the best of service for your own application development work in AWS.

Cloudwatch is a system for monitoring and managing AWS resources and It also provides alerts to notify users of any issues or problems with the system.

It offers many different ways to monitor and measure, such as collecting logs, metrics, and records from applications that run on AWS.

How CloudWatch Work in AWS?

AWS CloudWatch is a service that offers monitoring, notifications, and alarms for your AWS resources.

Cloudwatch monitors the state of the system you are interested in, pushes alerts to users or programs when it detects an issue, and enables you to set up automated actions based on its findings.

It is a built-in monitoring service offered by Amazon Web Services (AWS), which allows you to monitor your AWS resources, collect metrics, set alarms, and react to changes in your system.

Understanding the Dashboard and the Resources page

To get started with CloudWatch, you need to go to the dashboard. The dashboard has three main components:

1. The Resources page

2. The Metrics page

3. The Alarms page

Monitoring with CloudWatch

Cloudwatch is a service that tracks and monitors the resources in your AWS account. You can use it to keep track of metrics like CPU or network utilization and also see which services and applications are running on your account.

CloudWatch is a service that provides an easy way to monitor and take care of infrastructure in the cloud.

The service monitors many metrics, but it can also be configured to watch for specific conditions, such as detecting when disk space reaches a certain threshold.

If your service fails to meet your desired level of availability, CloudWatch can be configured to take corrective action, such as reconfiguring the underlying virtual machine.

Setting up alerts with CloudWatch

CloudWatch is a monitoring service that AWS offers. It provides a wide range of metrics and allows you to create different types of alerts to notify you when certain thresholds have been met.

Cloudwatch sends you alerts when these resources go above a certain threshold, so if something unexpected happens with your account, you’ll know soon enough.

With CloudWatch, you can set more than ten different metrics on the same group, giving you a comprehensive overview of your AWS resources.

What is the cost of Cloudwatch in AWS?

Since CloudWatch comprises of quite a few different functionalities, pricing reflects that same approach. Each CloudWatch function has a different price.

Each is different by region as usual, but here’s a rundown of pricing in the Oregon region. CloudWatch alarms cost 10 cents per alarm per month.

Ingesting logs into CloudWatch costs 50 cents per gigabyte and 3 cents per gigabyte for any archived logs.

CloudWatch also allows you to create custom dashboards with the available metrics, and those will cost you $3 per dashboard per month.

And again, there’s a free tier, giving you the opportunity to try most of these features before you have to drop any cash.

Features of Cloudwatch in AWS

One of my favorite features of CloudWatch is the ability to set up alarms to monitor a multitude of metrics for different Amazon services.

For each alarm, you choose from a pre‑existing set of metrics for each service. Once you’ve chosen the metric, you will then set a threshold for the alarm and actions to take.

Actions can range from notifying you via email or SMS to triggering some auto-scaling action within an EC2 auto-scaling group.

CloudWatch can also consume, aggregate, and monitor logs. This is simply accomplished by installing and configuring an awslogs agent on your EC2 instances and telling it which logs to send to CloudWatch.

Once the agent is installed in sending logs, CloudWatch can be configured to filter the logs and send alerts based on the criteria you define.

An example of that is tracking how many times a certain exception happens in your logs and then send a notification once it’s occurred a set number of times.

Top Use of CloudWatch in AWS

1. CloudWatch Work is a web-based tool for remote monitoring of servers, applications, and network devices.
2. It Work provides access to information about resource utilization, CPU load, I/O activity, and other metrics gathered from the AWS Cloud.
3. CloudWatch Work also provides notifications on events such as alerts and high latency issues. These notifications are delivered via email or SMS to alert administrators of possible issues.
4. Cloudwatch is an AWS service that provides monitoring and logging for your cloud apps.
5. It also monitors the capacity of each component in your system, such as virtual machines and databases.
6. To use CloudWatch, you first need to configure it as a resource in the AWS console. You can then either use the console or API-based tools to create dashboards and set alarms to measure key metrics.

Conclusion

When a company decides that they want to use the cloud for their business, one of the first questions they ask is if it is reliable.

AWS has a variety of different services that have been designed to make sure that it remains so and makes development work easy.

One way is with CloudWatch which monitors and collects data from other AWS services to give an overview of the health and performance of its computing platform.
