Viewing CloudWatch logs for capacity providers

You can view Amazon CloudWatch Logs logs for your capacity provider using the Lambda console, the CloudWatch console, or the AWS Command Line Interface (AWS CLI). Follow the instructions in the following sections to access your capacity provider's logs.

Stream logs with CloudWatch Logs Live Tail

Amazon CloudWatch Logs Live Tail helps you quickly troubleshoot your capacity providers by displaying a streaming list of new log events in real time. You can view and filter ingested logs from your capacity provider, helping you to detect and resolve issues quickly.

Note

Live Tail sessions incur costs by session usage time, per minute. For more information about pricing, see Amazon CloudWatch Pricing.

To start a Live Tail session, open your capacity provider's log group in the CloudWatch console and choose Live Tail. For more information, see Use Live Tail to view logs in near real time in the Amazon CloudWatch User Guide.

View logs with the AWS CLI

To view logs using the AWS CLI, use the aws logs commands. The following example retrieves the most recent log events for a capacity provider:

aws logs get-log-events \
  --log-group-name /aws/lambda/capacity-provider/my-capacity-provider \
  --log-stream-name my-capacity-provider/managed-instances

You can also use CloudWatch Logs Insights to query and analyze your capacity provider system logs. The following example queries for all ERROR level events:

aws logs start-query \
  --log-group-name /aws/lambda/capacity-provider/my-capacity-provider \
  --start-time $(date -d '1 hour ago' +%s) \
  --end-time $(date +%s) \
  --query-string 'fields @timestamp, @message | filter level = "ERROR" | sort @timestamp desc'
