### Description{% #description %}

Kubernetes Engine clusters must have Stackdriver Monitoring enabled by setting the `monitoring_service` attribute to `"monitoring.googleapis.com/kubernetes"` or leaving it undefined to use the default monitoring. Disabling monitoring by setting `monitoring_service = "none"` removes visibility into cluster performance, health, and security events, increasing the risk of undetected failures or malicious activity.

A secure configuration should include:

```
resource "google_container_cluster" "example" {
  name               = "secure-cluster"
  location           = "us-central1-a"
  initial_node_count = 3
  monitoring_service = "monitoring.googleapis.com/kubernetes"
}
```

If left unaddressed, this misconfiguration can prevent prompt detection and remediation of operational or security incidents, potentially leading to service outages or breaches.

## Compliant Code Examples{% #compliant-code-examples %}

```terraform
#this code is a correct code for which the query should not find any result
resource "google_container_cluster" "negative1" {
  name               = "marcellus-wallace"
  location           = "us-central1-a"
  initial_node_count = 3
  monitoring_service = "monitoring.googleapis.com/kubernetes"

  timeouts {
    create = "30m"
    update = "40m"
  }
}

# Monitoring service defaults to Stackdriver, so it's okay to be undefined
resource "google_container_cluster" "negative2" {
  name               = "marcellus-wallace"
  location           = "us-central1-a"
  initial_node_count = 3
  
  timeouts {
    create = "30m"
    update = "40m"
  }
}
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```terraform
#this is a problematic code where the query should report a result(s)
resource "google_container_cluster" "positive1" {
  name               = "marcellus-wallace"
  location           = "us-central1-a"
  initial_node_count = 3
  monitoring_service = "none"

  timeouts {
    create = "30m"
    update = "40m"
  }
}

resource "google_container_cluster" "positive2" {
  name               = "marcellus-wallace"
  location           = "us-central1-a"
  initial_node_count = 3
  monitoring_service = "monitoring.googleapis.com"

  timeouts {
    create = "30m"
    update = "40m"
  }
}
