# CLOUD AZURE FUNCTIONS DataDog monitors
|
|
|
|
## How to use this module
|
|
|
|
```
|
|
module "datadog-monitors-cloud-azure-functions" {
|
|
source = "git::ssh://git@git.fr.clara.net/claranet/pt-monitoring/projects/datadog/terraform/monitors.git//cloud/azure/functions?ref={revision}"
|
|
|
|
environment = "${var.environment}"
|
|
message = "${module.datadog-message-alerting.alerting-message}"
|
|
|
|
functions_max_scale_count = 2
|
|
}
|
|
|
|
```
|
|
|
|
## Purpose
|
|
|
|
Creates DataDog monitors with the following checks:
|
|
|
|
- Function App connections count too high
|
|
- Function App HTTP 5xx errors too high
|
|
- Function App threads count too high
|
|
|
