+# DATABASE PROXYSQL DataDog monitors
+
+## How to use this module
+
+```hcl
+module "datadog-monitors-database-proxysql" {
+  source      = "claranet/monitors/datadog//database/proxysql"
+  version     = "{revision}"
+
+  environment = var.environment
+  message     = module.datadog-message-alerting.alerting-message
+}
+
+```
+
+## Purpose
+
+Creates DataDog monitors with the following checks:
+
+- ProxySQL Client connections aborted
+- ProxySQL Pool connections failure
+- ProxySQL Server connections aborted
+- ProxySQL Slow queries
+- ProxySQL Thread Worker
+
