# CLOUD AWS ELASTICACHE COMMON DataDog monitors
|
|
|
|
## How to use this module
|
|
|
|
```
|
|
module "datadog-monitors-cloud-aws-elasticache-common" {
|
|
source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/aws/elasticache/common?ref={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
|
|
|
|
