# CLOUD AZURE APP-GATEWAY DataDog monitors

## How to use this module

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

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

```

## Purpose

Creates DataDog monitors with the following checks:

- App Gateway backend connect time is too high
- App Gateway backend HTTP 4xx errors rate is too high
- App Gateway backend HTTP 5xx errors rate is too high
- App Gateway backend unhealthy host ratio is too high
- App Gateway failed requests
- App Gateway has no connection
- App Gateway HTTP 4xx errors rate is too high
- App Gateway HTTP 5xx errors rate is too high
- App Gateway is down
