# DATABASE MONGODB DataDog monitors

## How to use this module

```hcl
module "datadog-monitors-database-mongodb" {
  source      = "claranet/monitors/datadog//database/mongodb"
  version     = "{revision}"

  environment = var.environment
  message     = module.datadog-message-alerting.alerting-message
}

```

## Purpose

Creates DataDog monitors with the following checks:

- MongoDB primary state
- MongoDB replication lag
- MongoDB secondary missing
- MongoDB too much servers or wrong monitoring config
