# CLOUD AZURE FUNCTIONS DataDog monitors

## How to use this module

```
module "datadog-monitors-cloud-azure-functions" {
  source = "git::ssh://git@git.fr.clara.net/claranet/pt-monitoring/projects/datadog/terraform/monitors.git//cloud/azure/functions?ref={revision}"

  environment = "${var.environment}"
  message     = "${module.datadog-message-alerting.alerting-message}"
}

```

## Purpose

Creates DataDog monitors with the following checks:

- Function App connections count too high
- Function App HTTP 5xx errors too high
- Function App threads count too high
