aws-logs 命令

常用示例

说明

aws logs is a subcommand of the AWS CLI that manages Amazon CloudWatch Logs, a service for monitoring, storing, and accessing log files from AWS resources and applications. Logs are organized into log groups (containers) and log streams (sequences of events from a single source). Log events contain a timestamp and raw message. Many AWS services like Lambda, ECS, and API Gateway automatically send logs to CloudWatch. CloudWatch Logs Insights enables SQL-like queries across log data. Metric filters extract metrics from log patterns. Subscription filters stream logs to Lambda, Kinesis, or Firehose in real-time.
