Now our API Gateway requests should be logged via CloudWatch. Scroll to the bottom of the page and click Save Changes.

Check Log full requests/responses data to include entire request and response body in the log.Select INFO for Log level to log every request.For the case of our Notes App API, we deployed to the prod stage. Select your API project from the left panel, select Stages, then pick the stage you want to enable logging for. Go back to your AWS Console and select API Gateway from the list of services.Įnter the ARN of the IAM role we just created in the CloudWatch log role ARN field and hit Save. Now that we have created our IAM role, let’s turn on logging for our API Gateway project. In our case, we called our role APIGatewa圜loudWatchLogs. Then we need to turn on logging for our API project.įirst, log in to your AWS Console and select IAM from the list of services.Įnter a Role name and select Create role.
First, we need to create an IAM role that allows API Gateway to write logs in CloudWatch. In the chapter we are going to look to do the following: Using the analogy of server logs and application logs, you can roughly think of the API Gateway logs as your server logs and Lambda logs as your application logs. Amazon CloudWatch is a monitoring service to help you collect and track metrics for your resources. In the serverless environment, we have lesser control over the underlying infrastructure, logging is the only way to acquire knowledge on how the application is performing.
It could contain everything from unexpected function failures, to key events for understanding how users behave. It usually contains errors, warnings, and informational events. Each log entry contains the information about the request, including client IP address, request date/time, request path, HTTP code, bytes served, user agent, etc.Īpplication logs are a file of events that are logged by the web application. Web server logs maintain a history of requests, in the order they took place. There are 2 types of logs we usually take for granted in a monolithic environment.
It gives us visibility into how we are processing and responding to incoming requests.
But unless you are trying to waste money and time, I don't know why you would pick this option over #2, the existing Export to S3 feature.Logging is an essential part of building backends and it is no different for a serverless API. If you want to write a program to scan your log groups, read all the logs from the log group into your Lambda, and then write them back to S3, you can use DescribeLogStreams and GetLogEvents. It can be a bit tricky to set up the IAM permissions correctly, but I recommend using this approach to dumping rather than reading the logs yourself, because it will cost you less in terms of data transfer and Lambda compute costs, lets you offload the programming effort onto CloudWatch since they've already implemented it, and has some built-in resilience that you would otherwise have to implement yourself. The relevant API operations are CreateExportTask, DescribeExportTasks, and CancelExportTask. If you just want to dump ALL logs into S3, CloudWatch has a specific feature for this, it is called Export to S3. If you can possibly use Go instead of Python, check out the Incite library, it really simplifies the process of querying logs in GoLang. If you are doing querying with Insights I strongly recommend using a more user-friendly library. The relevant API operations are StartQuery and GetQueryResults. If you really want to "Query" your logs, meaning extract a subset of the logs that match some criteria, you want to use CloudWatch Logs Insights. Here is some documentation for the CloudWatch Logs API, which I believe is current: Your Lambda function can simply call the CloudWatch Logs service using the SDK, pull down the logs you want, and send them to S3. Ultimately the answer is to use the AWS SDK in for your language (Python = boto3) and in particular utilize the CloudWatch Logs API.
