+# CLOUD GCP CLOUD-SQL COMMON DataDog monitors
+
+## How to use this module
+
+```
+module "datadog-monitors-cloud-gcp-cloud-sql-common" {
+  source = "git::ssh://git@bitbucket.org/morea/terraform.feature.datadog.git//cloud/gcp/cloud-sql/common?ref={revision}"
+
+  environment = "${var.environment}"
+  message     = "${module.datadog-message-alerting.alerting-message}"
+}
+
+```
+
+## Purpose
+
+Creates DataDog monitors with the following checks:
+
+- Cloud SQL CPU Utilization
+- Cloud SQL Disk Utilization forecast
+- Cloud SQL Disk Utilization
+- Cloud SQL Failover Unavailable
+- Cloud SQL Memory Utilization forecast
+- Cloud SQL Memory Utilization
