+# 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
