Your applications and infrastructure resources may be monitored and managed using Amazon CloudWatch, which offers a unified solution. It is a web service you can use to gather metrics, understand your application and the infrastructure supporting it, and automatically respond to changes. You can monitor AWS resources with Amazon CloudWatch and adjust the monitoring to your company's requirements.
Different types of Cloud Services include
The owner of the AWS resources will be comparable to an administrator user. It can grant access to other users for the AWS resources that add, delete, change, or inspect the resources. Administrator access is provided with Power User Access but without the ability to control users and permissions.
In other words, a user who has Power User Access can create, delete, change, or view the resources but cannot allow other users access.
CloudWatch Logs is a tool that helps us monitor and troubleshoot our systems and applications. It uses our already-established systems, applications, and custom log files. In addition, it allows us to monitor our logs in real-time for particular phrases, values, or patterns.
A data point in a time series representing a particular measurement that occurs within your AWS environment is referred to as a metric. To monitor your environment and determine any problems, you can use CloudWatch to gather and track metrics generated by AWS resources.
The agent that collects CloudWatch logs can run on many different systems. Here is a list of a few things that are:

fields @timestamp, @message
| filter @message like /ERROR/
| sort @timestamp desc
| limit 20
We can keep a record of your information for as long as we think is necessary, which gives us the freedom to change the LogGroup retention settings whenever we see fit. It also allows us to keep a record of our metadata indefinitely.
If you want to delete the alarms from the AWS CloudWatch Console, use the following command:
Command: aws cloudwatch delete-alarms --region us-east-2 --alarm-names ...
You may gather and keep track of measurements in a timeframe that is close to real-time by using AWS CloudWatch. The information regarding its metrics is kept as time-series data points. In addition, each data point in a time series is accompanied by a timestamp as well as a unit of measurement.
The new Amazon CloudWatch ServiceLens feature lets you visualize and evaluate your apps' health, performance, and availability from a single location. It is possible to use Amazon CloudWatch ServiceLens in any of the public AWS Regions equipped with AWS-X-Ray.
Installing the CloudWatch agent on AWS EC2 instances allows you to integrate CloudWatch with those instances. You can collect metrics and log files from your EC2 instances using the CloudWatch agent and then submit them to CloudWatch.

You can determine which CloudWatch operations a user associated with your AWS Account can carry out using the integration that CloudWatch provides with AWS Identity and Access Management (IAM). Using IAM to restrict who can view the data in CloudWatch for particular resources is impossible. It is impossible to give a single individual access to the CloudWatch data for, for example, just one group of instances or a single LoadBalancer. All cloud resources that CloudWatch uses are subject to the permissions that IAM grants. Furthermore, IAM roles are not supported by the Amazon CloudWatch command line tools.
Amazon CloudWatch Synthetics allows you to build schedule-driven canaries and scriptable checks of your APIs and endpoints. Since canaries navigate your applications the same way humans would, you can verify the quality of the user experience at all times, regardless of whether or not there is any actual human traffic. Using canaries, you can find issues before your consumers do.
Both services offer interchangeable functionalities, such as constructing dashboards, creating alarms, and seeing logs. Nevertheless, there are many significant distinctions between the two services. For Instance, in contrast to Google Stackdriver, Amazon CloudWatch incorporates the capability for monitoring Amazon DynamoDB tables. In addition, Google Kubernetes Engine clusters are available through Google Stackdriver. However, it is not available through Amazon CloudWatch.

Canaries are pre-programmed scripts that run on a predetermined schedule. You can use Amazon CloudWatch Synthetics to create canaries to monitor your endpoints and APIs. The canaries travel the same routes as consumers and perform the same tasks, allowing you to validate the quality of the user experience even when no actual customer activity is occurring on your apps. You can detect problems before your clients do by using canaries.
By simulating the queries of potential visitors, a method known as "synthetic monitoring" can be used to evaluate the availability, performance, and functionality of a website or online service.
An AWS CloudWatch Alarm is a monitoring and management solution for AWS resources. It enables the configuration of alarms based on individual indicators or as part of a larger monitoring plan.
As a new kind of metric stream, CloudWatch Metric Streams allow you to track and collect information from Amazon CloudWatch. They allow for the aggregation, visualization, and analysis of all information gathered by CloudWatch.
CloudTrail is the tool used for continuous monitoring. The API calls your apps can be tracked with CloudTrail. The logs also include details about each API request performed by AWS services.

If you have access to the AWS Management Console, you can also use it to create Thresholds that will cause a Cloudwatch alarm to go off.
Amazon CloudWatch Logs uses your existing machine, application, and custom log files to reveal and troubleshoot your systems and programs. With CloudWatch Logs, you can search your logs in near real-time for specific phrases, values, or patterns. For example, you can set the alarm for the number of errors in your machine logs or view graphs of net request latency from your utility logs. You can then examine the distinct log records to determine the source of the problem. Log statistics can be stored and accessed indefinitely in a long-lasting, low-cost garage, so you don't have to worry about filling up difficult drives.
CloudWatch Logs helps you display and troubleshoot your systems and applications using your existing machine, software, and custom log files. CloudWatch Logs allows you to monitor your logs in real-time for specific phrases, values, or styles.
Any CloudWatch measure can be displayed via an alarm you set up. You can also set off an alert based on metrics specific to your application or system.
Cloudwatch logs might help you determine why your program isn't functioning as intended. You can also use them to diagnose performance issues in your system. Furthermore, Cloudwatch logs can be used to keep an eye on the status of your infrastructure and spot problems before they affect performance.

No, the metrics data will not be lost.
If you disable monitoring for an EC2 instance, the metrics you've collected are still safely preserved in a SQL database as part of the AWS CloudTrail logs.
Metrics data for deleted ELBs and decommissioned EC2 instances are still available. MetricsData associated with a terminated instance will be removed when the Instance is shut down. In contrast, MetricsData associated with your account will remain on the MetricInfraService until you delete it. This information can be used for diagnosing problems with your ECS cluster or ELB.
CloudWatch lets you see and visualize numerous statistics. A few examples are as follows:
Some of the many uses for CloudWatch logs include the following.
When it comes to cloud-based computing power, nothing beats the flexibility and scalability of AWS Elastic Compute Cloud. With EC2, users only need to wait a few minutes to obtain and restart the most recent user instances instead of the days it used to take. Getting a new server requires placing a purchase order and doing cabling, which might take a lot of time.
An on-premises, hybrid, and AWS application or resource can be monitored and managed with Amazon CloudWatch, which offers data and valuable insights.
Yes, Amazon CloudWatch is available for free to use. Metrics for the majority of AWS Services (EC2, S3, Kinesis, etc.) are sent directly and for free to CloudWatch. These constraints on the free tier should be sufficient for many apps.
