# 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
|
|
|
|
## Requirements
