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

## Notes
|
|
|
|
It could be not possible to modify `innodb_buffer_pool_size` or `innodb_buffer_pool_instances` mysql parameters (i.e. cloudsql).
|
|
In this case, InnoDB Pool monitors could be less useful for optimization even if they could inform when an instance should be upsized.
