# CLOUD AWS LAMBDA DataDog monitors

## How to use this module

```hcl
module "datadog-monitors-cloud-aws-lambda" {
  source      = "claranet/monitors/datadog//cloud/aws/lambda"
  version     = "{revision}"

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

```

## Purpose

Creates DataDog monitors with the following checks:

- Lambda Invocations throttled due to concurrent limit reached
- Lambda Number of errors
- Lambda Number of invocations (disabled by default)
- Lambda Percentage of errors
