AWS ElasticCache Redis Service DataDog monitors

How to use this module

module "datadog-monitors-aws-elasticcache-redis" {
  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/aws/elasticache/redis?ref={revision}"

  message           = "${module.datadog-message-alerting.alerting-message}"
  environment       = "${var.environment}"
  elasticache_size  = "${var.size_of_elsaticache}"
  nodes             = "${data.my_cluster.num_cache_nodes}"
}

You can retrieve the number of nodes using the data source :

data "aws_elasticache_cluster" "my_cluster" {
  cluster_id = "my-cluster-id"
}

Purpose

Creates DataDog monitors with the following checks:

• Cache hits
• CPU high
• Commands received
• Replication lag
• Swap
• Free memory
