# CLOUD AWS ELASTICACHE REDIS DataDog monitors
|
|
|
|
## How to use this module
|
|
|
|
```
|
|
module "datadog-monitors-cloud-aws-elasticache-redis" {
|
|
source = "git::ssh://git@github.com/claranet/terraform-datadog-monitors.git//cloud/aws/elasticache/redis?ref={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
|
|
|
|
