CLOUD AWS ELASTICACHE REDIS DataDog monitors

How to use this module

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

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

Purpose

Creates DataDog monitors with the following checks:

• Elasticache redis cache hit ratio
• Elasticache redis CPU
• Elasticache redis is receiving no commands
• Elasticache redis replication lag

Requirements

No requirements.
