What is AWS Cloudwatch?

Amazon CloudWatch screens your Amazon Web Services (AWS) assets and the applications you run on AWS continuously. You can utilize CloudWatch to gather and track measurements, which are factors you can quantify for your assets and applications. The CloudWatch landing page naturally shows measurements about each AWS administration you use. You can moreover make custom dashboards to show measurements about your custom applications and show custom assortments of measurements that you pick.

Amazon CloudWatch is a checking and recognizability administration that worked for DevOps engineers, designers, site unwavering quality specialists (SREs), and IT chiefs. CloudWatch furnishes you with information and noteworthy bits of knowledge to screen your applications, react to framework wide execution changes, advance asset usage, and get a bound together perspective on operational wellbeing. CloudWatch gathers checking and operational information as logs, measurements, and occasions, furnishing you with a brought together perspective on AWS assets, applications, and administrations that sudden spike in demand for AWS and on-premises servers. You can utilize CloudWatch to identify peculiar conduct in your surroundings, set cautions, picture logs and measurements one next to the other, take robotized activities, investigate issues, and find experiences to keep your applications running easily.

You can make alerts that watch measurements and send warnings or consequently make changes to the assets you are checking when a limit is penetrated. For instance, you can screen the CPU utilization and plate peruses and composes of your Amazon EC2 occasions and afterward utilize this information to decide if you should dispatch extra occurrences to deal with an expanded burden. You can likewise utilize this information to stop under-utilized cases to set aside cash.

With CloudWatch, you gain framework wide perceivability into asset usage, application execution, and operational wellbeing.

Working:

Amazon CloudWatch is fundamentally a metrics store. An AWS service, for example, Amazon EC2—places metrics into the archive, and you recover insights dependent on those measurements. In the event that you put your own custom measurements into the vault, you can recover insights on these measurements too. You can utilize metrics to figure insights and afterward present the information graphically in the CloudWatch support. 

You can design caution activities to stop, start, or end an Amazon EC2 instance when certain models are met. Likewise, you can make alerts that start Amazon EC2 Auto Scaling and Amazon Simple Notification Service (Amazon SNS) activities for your benefit. For more data about making CloudWatch alerts, see Alarms. AWS Cloud figuring assets are housed in exceptionally accessible server farm offices. To give extra adaptability and unwavering quality, every server farm office is situated in a particular geological zone, known as a Region. Every Region is intended to be totally disengaged from different Regions, to accomplish the best conceivable disappointment confinement and security. Measurements are put away independently in Regions, yet you can utilize CloudWatch cross-Region usefulness to total insights from various Regions.

Benefits:

Present-day applications, for example, those running on microservices structures produce enormous volumes of information like measurements, logs, and occasions. Amazon CloudWatch empowers you to gather, access, and relate this information on a solitary stage from over all your AWS assets, applications, and administrations that sudden spike in demand for AWS and on-premises servers, helping you separate information storehouses so you can without much of a stretch increase framework wide permeability and rapidly resolve issues.

Checking your AWS assets and applications is simple with CloudWatch. It locally incorporates with more than 70 AWS administrations, for example, Amazon EC2, Amazon DynamoDB, Amazon S3, Amazon ECS, Amazon EKS, and AWS Lambda, and naturally distributes point by point 1-minute measurements and custom measurements with as long as 1-second granularity so you can plunge profound into your logs for the extra setting. You can likewise utilize CloudWatch in half and half cloud designs by utilizing the CloudWatch Agent or API to screen your on-premises assets.

Amazon CloudWatch empowers you to set cautions and computerize activities dependent on either predefined limits, or on AI calculations that distinguish strange conduct in your measurements. For instance, it can begin Amazon EC2 Auto Scaling naturally or stop a case to decrease charging overages. You can likewise utilize CloudWatch Events for serverless to trigger work processes with administrations like AWS Lambda, Amazon SNS, and AWS CloudFormation.

To improve execution and asset usage, you need a brought together operational view, ongoing granular information, and recorded reference. CloudWatch gives programmed dashboards, information with 1-second granularity, and as long as 15 months of measurements stockpiling and maintenance. You can likewise perform metric math on your information to determine operationally and use bits of knowledge; for instance, you can total utilization over a whole armada of EC2 occurrences.

CloudWatch empowers you to investigate, break down, and envision your logs so you can investigate operational issues easily. With CloudWatch Logs Insights, your just compensation for the questions you run. It scales with your log volume and question multifaceted nature furnishing your responses in short order. Also, you can distribute log-based measurements, make alerts, and connect logs and measurements together in CloudWatch Dashboards for complete operational perceivability.

Use cases:

Log analytics:

Explore, analyze, and visualize your logs to address operational issues and improve application execution. You can perform inquiries to help you rapidly and successfully react to operational issues. On the off chance that an issue happens, you can begin questioning quickly utilizing a reason fabricated inquiry language to quickly distinguish expected causes.

Application monitoring

Screen your applications that sudden spike in demand for AWS (on Amazon EC2, compartments, and serverless) or on-premises. CloudWatch gathers information at each layer of the presentation stack, remembering measurements and logs for programmed dashboards.

Resource optimization

CloudWatch cautions watch your measurement esteems against edges that it is possible that you determine, or that CloudWatch makes for you utilizing AI models to distinguish abnormal conduct. On the off chance that an alert is activated, CloudWatch can make a move naturally to empower Amazon EC2 Auto Scaling or stop an occasion, for instance, so you can mechanize limit and asset arranging.

Resolution improvement:

CloudWatch causes you to relate, imagine, and examine measurements and logs, so you can act rapidly to determine issues, and join them with follow information from AWS X-Ray for start to finish discernibleness. You can likewise dissect client solicitations to help accelerate investigating and troubleshooting, and decrease by and large interim to-goals (MTTR).

Infrastructure monitoring and troubleshooting:

Screen key measurements and logs, envision your application and foundation stack, make cautions, and associate measurements and logs to comprehend and resolve the main driver of execution issues in your AWS assets. This incorporates checking your holder's biological system across Amazon ECS, AWS Fargate, Amazon EKS, and Kubernetes.
