What is AWS CloudWatch?

AWS CloudWatch is an automatic monitoring service for your cloud applications and AWS services. It gathers and maintains log files and performance data from various services, including EC2 instances, RDS servers, VPCs, Lambda operations, and many others. You may generate a stream of events, set off alarms, and take other actions using AWS CloudWatch to watch your AWS account and resources. If you want to know What is AWS CloudWatch?

AWS CloudWatch offers visibility into your Aws services so you can keep an eye on their operation, performance, and resource usage. These insights might help you maintain your app and maintain it operating efficiently.

AWS CloudWatch comprises two separate services marketed together as “CloudWatch.”

  • A service for managing and collecting operational and resource performance metrics.
  • A logging service for collecting, managing, and storing usage and service logs.

The Metrix service offers data collection, storage, dashboards, event filtering, and alarms for resource metrics. The event service and the alarm system have the names “CloudWatch Events” and “CloudWatch Alarms,” respectively.

The CloudWatch Logs-branded logging service offers log data collecting, storage, and archiving, and CloudWatch Logs Insights, a simple log viewer and query tool.

CloudWatch Logs Service

An integrated blogging platform for your applications, Amazon’s services, and architecture, AWS Cloudwatch Logs. It offers log data gathering, storage, retention policies, and basic administrative functions.

An integrated log capturing and storage repository is what CloudWatch Logs offers as its main benefit. 

AWS services use CloudWatch Logs as their monitoring service when they publish log data. Having a single, reliable collection and internet connection for log data is quite helpful. Lambda, VPC flow reports, and RDS are just a few of the AWS services that produce log data that is transferred to CloudWatch logs and stored there.

Applications can use the EC2 CloudWatch agent, the AWS API, or the CLI to submit their reports to CloudWatch logs. There are plugins for several logging frameworks that make this coding-free.

For processing, logs can be transmitted to different destinations, such as CloudWatch logs, Lambda processes, or AWS ElasticSearch.

Although CloudWatch logs offer basic viewer and query functionality, most customers supplement their use of CloudWatch logs with a third-party logging solution that offers more sophisticated viewing and analysis tools.

Log Data

CloudWatch Logs uses log data in the form of time-stamped messages. The message can be written in any desired way, including plain text, JSON, and other formats. The structure of log messages is only partially understood by CloudWatch Logs, which normally treats the information as plain text.

Data are maintained and accessed through a two-level structure of defined record groups and streams. These can be regarded as files and folders in the file system. Logs are regional, which means that the AWS area in which they were collected is where they are kept and retrieved. Not every region shares the same perception of a record.

CloudWatch Logs Viewer

CloudWatch Logs offers a straightforward log reader. One log stream’s page of events can be viewed at a time. The log streams included in the log event data must be manually chosen before being shown. For many services, AWS will constantly create new streams. Here, we offer the training with the recently updated syllabus in AWS Training in Bangalore.
