Which of the following steps would be optimal for debugging these application issues?
(Choose two.)
Parse HTTP logs in Amazon API Gateway for HTTP errors to determine the root cause of the errors.
Parse Amazon CloudWatch Logs to determine processing times for requested images at specified intervals.
Parse VPC Flow Logs to determine if there is packet loss between the Lambda function and S3.
Parse AWS X-Ray traces and analyze HTTP methods to determine the root cause of the HTTP errors.
Parse S3 access logs to determine if objects being accessed are from specific IP addresses to narrow the scope to geographic latency issues.
Explanations:
Parsing HTTP logs in API Gateway helps identify HTTP errors but does not provide direct insight into issues with serverless components or timeout errors related to image loading and processing.
Parsing CloudWatch Logs for processing times can reveal delays in Lambda functions, helping identify bottlenecks in the image processing workflow that may be causing timeouts.
VPC Flow Logs help monitor network traffic but aren’t as relevant for determining latency issues between Lambda and S3 unless there are clear signs of networking issues, which is less likely given that the problem is tied to image loading.
AWS X-Ray traces can provide detailed insights into the performance of the serverless application, helping pinpoint delays in Lambda or API Gateway, and track the root cause of timeout errors.
S3 access logs help track requests to S3, but they aren’t typically helpful in identifying geographic latency or performance issues unless there is specific geographic filtering required, which isn’t directly linked to the described problem.
I categorize that the answer is:
Parse Amazon CloudWatch Logs to determine processing times for requested images at specified intervals.
