|
|
|
## How to use this module
|
|
|
|
```
|
|
module "datadog-monitors-system-generic" {
|
|
source = "git::ssh://git@git.fr.clara.net/claranet/cloudnative/projects/datadog/terraform/monitors.git//system/generic?ref={revision}"
|
|
|
|
environment = "${var.environment}"
|
|
message = "${module.datadog-message-alerting.alerting-message}"
|
|
|
|
free_memory_message = "${module.datadog-message-alerting.alerting-message-bh-only}"
|
|
}
|
|
|
|
```
|
|
|
|

|
|
|
|
Creates DataDog monitors with the following checks:
|
|
|
|

|
|
- CPU usage
|
|
- Disk Space forecast
|
|
- Free disk inodes
|
|
- Free disk space
|
|
- Free memory
