Amazon CloudWatch is a monitoring and observability service that provides insights into your AWS resources and applications by collecting and tracking metrics, logs, and events.
Amazon CloudWatch collects metrics, logs, and events. Metrics are data points about your resources and applications, logs are textual data generated by resources, and events provide insights into changes and notifications.
You can use CloudWatch to monitor resources by collecting and visualizing metrics, setting alarms for specific thresholds, and generating insights into resource performance.
CloudWatch metrics are data points about the performance of your resources and applications. They can include data like CPU utilization, network traffic, and more.
You can collect custom metrics in CloudWatch by using the CloudWatch API or SDKs to publish data to CloudWatch using the PutMetricData action.
CloudWatch alarms allow you to monitor metrics and set thresholds to trigger notifications or automated actions when specific conditions are met.
You can visualize CloudWatch metrics using CloudWatch Dashboards, which allow you to create customized views of metrics, graphs, and text.
CloudWatch Logs is a service that collects, stores, and monitors log files from various resources, making it easier to analyze and troubleshoot applications.
You can store logs in CloudWatch Logs by sending log data from your resources or applications using the CloudWatch Logs agent, SDKs, or directly through the CloudWatch API.
CloudWatch Logs Insights is a feature that allows you to query and analyze log data to gain insights into your applications and resources.
CloudWatch Events provides a way to respond to state changes in your AWS resources, such as launching instances, creating buckets, or modifying security groups.
You can use CloudWatch Events to trigger actions by defining rules that match specific events and associate those rules with targets like Lambda functions, SQS queues, and more.
CloudWatch Container Insights provides a way to monitor and analyze the performance of containers managed by services like Amazon ECS and Amazon EKS.
CloudWatch Contributor Insights provides insights into the top contributors affecting the performance of your resources, helping you identify bottlenecks and optimization opportunities.
You can use CloudWatch Logs for troubleshooting by analyzing log data, setting up alarms for specific log patterns, and correlating events to diagnose issues.
Yes, CloudWatch Logs Insights can query data from multiple log groups, allowing you to analyze and gain insights from a broader set of log data.
You can set up CloudWatch Alarms by defining a metric, setting a threshold for the metric, and specifying actions to be taken when the threshold is breached.
CloudWatch Anomaly Detection is a feature that automatically analyzes historical metric data to create a baseline and detect deviations from expected patterns.
You can use CloudWatch Cross-Account Cross-Region (CACR) to set up cross-account monitoring, allowing you to view metrics and alarms from multiple AWS accounts.
Yes, CloudWatch can integrate with other AWS services like Amazon EC2, Amazon RDS, Lambda, and more to provide enhanced monitoring and insights into resource performance.
