# 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
|
|
|
|

|
|
| Name | Version |
|
|
|------|---------|
|
|
| terraform | >= 0.12.26 |
