Just as we got a hang of monitoring our server-based applications, they take away the server. How do you monitor something that doesn’t exist? What metrics matter most in a serverless world? In this session, we will look at how applications are different in a AWS Lambda-based world and how to monitor them. Join us as we work our way through the stack and demonstrate how to capture the health and performance of your services.

STATELESS

6. Important AWS Lambda Concepts
SERVERLESS
AS FAR AS YOU ARE CONCERNED

7. What is a AWS Lambda Function
• Your executable code
• No restrictions
• Priced based on execution time, quantity, and memory

8. Adding AWS Lambda
to your infrastructure

20. Frameworks
node-lambda

32. Monitoring 101
the tl;dr version

33. Collecting data is
cheap

34. Collecting data is
cheap;
Not having it when you
need it can be
expensive

40. Monitoring AWS Lambda

41. What are the AWS Lambda Metrics
aws.lambda.duration, min, max, sum
aws.lambda.errors
aws.lambda.invocations
aws.lambda.iterator_age
aws.lambda.throttles

42. Three Options for Monitoring AWS Lambda
1. Add a custom metric to CloudWatch
2. Add metric directly to monitoring application
3. Add a line to the CloudWatch logs

43. How Datadog Does It
Add line to CloudWatch logs:
MONITORING|unix_epoch_timestamp|value|type|
my.metric.name|#tag1:value,tag2
