AWS X-Ray Demo

As previously mentioned, you can use X-Ray for tracing.

On the X-Ray service website, you can see the X-Ray service map.

The service map shows if the function calls succeeded or failed.

Green color is for success, and orange color is for failure.

Examining the Traces

Clicking on the function in the service map shows a graph of the response distribution.

The response distribution is shown with durations and response statuses.

By clicking on a trace you can see:

  • The flow from Lambda function to AWS S3
  • The Lambda's function errors
  • The error exeptions

Reading the Logs

By using structured logs, you can report on certain fields.

For example, you can specifically look for timestamp, status, request ID and message.

You can use CloudWatch Logs Insights to explore errors in more details.
