Terraform module for Datadog Aws Services

This module uses datadog's feature to monitor AWS Service status page. This blog post explains what we've set up Note that Datadog scrapes the status page from AWS and this can lag a bit.

This module is part of a larger suite of modules that provide alerts in Datadog. Other modules can be found on the Terraform Registry

We have two base modules we use to standardise development of our Monitor Modules:

• generic monitor Used in 90% of our alerts
• service check monitor

Modules are generated with this tool: https://github.com/kabisa/datadog-terraform-generator

Example Usage

module "aws_eu_west_1" {
  source = "kabisa/aws-services/datadog"

  for_each = toset([
    "cloudformation",
    "cloudtrail",
    "cloudwatch",
    "directconnect",
    "ec2",
    "ecr",
    "ecs",
    "eks",
    "elasticache",

    "sqs",
    "vpc",
  ])
  env                  = "prd"
  notification_channel = "[email protected]"

  include_tags = [
    "region:eu-west-1",
    "service:${each.key}"
  ]
  by_tags = [
    "service"
  ]
  name_suffix = each.key
}

Getting started developing

pre-commit was used to do Terraform linting and validating.

Steps:

• Install pre-commit. E.g. brew install pre-commit.
• Run pre-commit install in this repo. (Every time you clone a repo with pre-commit enabled you will need to run the pre-commit install command)
• That’s it! Now every time you commit a code change (.tf file), the hooks in the hooks: config .pre-commit-config.yaml will execute.
