# DATABASE MYSQL DataDog monitors
## How to use this module
```
module "datadog-monitors-database-mysql" {
source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//database/mysql?ref={revision}"
environment = "${var.environment}"
message = "${module.datadog-message-alerting.alerting-message}"
}
```
## Purpose
Creates DataDog monitors with the following checks:
- Mysql server does not respond
- Mysql Connections limit
- Mysql Aborted connects
- Mysql Slow queries
- Mysql Innodb buffer pool efficiency
- Mysql Innodb buffer pool utilization
- Mysql threads changed abnormally
- Mysql queries changed abnormally
