Introduction

This action leverages steadybit/failure-lambda and the AWS Systems Manager API to inject latency into an AWS Lambda.

Use Cases

• Understand how other (e.g. upstream services, monitoring) behaves when the lambda is answering to slow.

Prerequisites

The AWS Lambda Function to attack must be wrapped with the failure-lambda library.

Please note that multiple parallel failure injections on the same lambda function are not supported.

Parameters

Parameter	Description	Default
Duration	The duration of the attack.	30s
Rate	The rate of invocations to affect. (100 = all request, 50 = half of all requests)	100%
Minimum Latency	Minimum latency to inject.	500ms
Maximum Latency	Maximum latency to inject.	500ms
