# CLOUD AZURE FUNCTIONS DataDog monitors
## How to use this module
```hcl
module "datadog-monitors-cloud-azure-functions" {
source = "claranet/monitors/datadog//cloud/azure/functions"
version = "{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

| Name | Version |
|------|---------|
| <a name="requirement_terraform"></a> [terraform](#requirement\_terraform) | >= 0.12.31 |
| <a name="requirement_datadog"></a> [datadog](#requirement\_datadog) | >= 3.1.0 |
## Providers
| Name | Version |
|------|---------|
| <a name="provider_datadog"></a> [datadog](#provider\_datadog) | 3.1.2 |
## Modules
| Name | Source | Version |
|------|--------|---------|
| <a name="module_filter-tags"></a> [filter-tags](#module\_filter-tags) | ../../../common/filter-tags | n/a |
