+# CLOUD AWS LAMBDA DataDog monitors
+
+## How to use this module
+
+```
+module "datadog-monitors-cloud-aws-lambda" {
+  source = "git::ssh://git@git.fr.clara.net/claranet/pt-monitoring/projects/datadog/terraform/monitors.git//cloud/aws/lambda?ref={revision}"
+
+  environment = var.environment
+  message     = module.datadog-message-alerting.alerting-message
+}
+
+```
+
+## Purpose
+
+Creates DataDog monitors with the following checks:
+
+- Lambda Number of Errors
+- Lambda Number of Invocations (disabled by default)
+- Lambda Number of Throttles
+- Lambda Percentage of errors
+
