Amazon CloudWatch

Amazon CloudWatch is an AWS tool primarily for monitoring cloud and on-premises infrastructures. CloudWatch tracks and collects insights, called metrics, from the monitored AWS resources in the form of a time-ordered set of data points.

CloudWatch also offers a centralized logging system, called CloudWatch logs, that allows us to collect, compile, and analyze any log files from various AWS resources. With CloudWatch logs, we can detect real-time operational changes in cloud resources.

Key resources of CloudWatch

Here’s a list of key CloudWatch concepts that we need to know about:

• Metrics: A metric represents a set of time-ordered data points about the specific aspects of a resource, such as CPU usage, memory consumption, or network traffic, providing valuable insights into the operational state of that resource.

• CloudWatch Logs: CloudWatch Logs are real-time log data from different AWS resources and services that we can use to understand and troubleshoot any performance and operational issues.

• CloudWatch statistic: CloudWatch statistic is an aggregation of metric data over a defined time interval. Each statistic also has a unit of measure. ...
