Step 3: Test the Lambda function - Amazon ElastiCache
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Step 3: Test the Lambda function

In this step, you invoke the Lambda function manually using the invoke command. When the Lambda function executes, it generates a UUID and writes it to the ElastiCache cluster that you specified in your Lambda code. The Lambda function then retrieves the item from the cache.

  1. Invoke the Lambda function (AccessMemCache) using the Amazon Lambda invoke command.

    For Linux, OS X, or Unix:

    aws lambda invoke \ --function-name AccessMemCache \ --region us-east-1 \ --profile adminuser \ output.txt

    For Windows:

    aws lambda invoke ^ --function-name AccessMemCache ^ --region us-east-1 ^ --profile adminuser ^ output.txt
  2. Verify that the Lambda function executed successfully as follows:

    • Review the output.txt file.

    • Review the results in the Amazon Lambda console.

    • Verify the results in CloudWatch Logs.
