CLOUD AWS ELASTICACHE COMMON DataDog monitors

How to use this module

module "datadog-monitors-cloud-aws-elasticache-common" {
  source      = "claranet/monitors/datadog//cloud/aws/elasticache/common"
  version     = "{revision}"

  environment = var.environment
  message     = module.datadog-message-alerting.alerting-message
}

Purpose

Creates DataDog monitors with the following checks:

  • Elasticache connections
  • Elasticache eviction
  • Elasticache evictions is growing
  • Elasticache free memory
  • Elasticache max connections reached
  • Elasticache swap

Requirements

Name Version
terraform >= 0.12.26
