# CLOUD AWS RDS COMMON DataDog monitors
|
|
|
|
## How to use this module
|
|
|
|
```
|
|
module "datadog-monitors-cloud-aws-rds-common" {
|
|
source = "git::ssh://git@git.fr.clara.net/claranet/pt-monitoring/projects/datadog/terraform/monitors.git//cloud/aws/rds/common?ref={revision}"
|
|
|
|
environment = var.environment
|
|
message = module.datadog-message-alerting.alerting-message
|
|
}
|
|
|
|
```
|
|
|
|
## Purpose
|
|
|
|
Creates DataDog monitors with the following checks:
|
|
|
|
- RDS instance CPU high
|
|
- RDS instance free space
|
|
- RDS replica lag
|
|
|
|
