N.B. Releases >= 2.0.0 been upgraded to use Terraform 0.12.n.
Terraform module to setup cloudwatch alerts and push them to SNS. This repository contains the following modules:
api-gateway: Creates general alerts for the api-gateway.dynamodb: Creates the alerts needed for a dynamodb table.kinesis: Creates alerts for a kinesis stream. This is used in theskyscrapers/terraform-kinesismodule.lambda_function: Creates the alerts for lambda functions.
Creates general alerts for the API-Gateway.
N.B. Releases >= 2.0.0 the 5XXError... variables are now fiveXXError... as variables cannot start with a number.
