# Configure notification alerts using Terraform

Notification alerts configurations in [Knowledge Graph](/docs/grafana-cloud/knowledge-graph/) allow you to manage how alerts are processed and routed. You can specify match labels to filter alerts, add custom labels, set duration requirements, and control silencing.

For information about configuring notification alerts in the Knowledge Graph UI, refer to [Configure notifications](/docs/grafana-cloud/knowledge-graph/configure/notifications/).

## Basic notification alerts configuration

Create a file named `alert-configs.tf` and add the following:

```terraform
# Basic alert configuration with silencing
resource "grafana_asserts_notification_alerts_config" "prometheus_remote_storage_failures" {
  provider = grafana.asserts

  name = "PrometheusRemoteStorageFailures"

  match_labels = {
    alertname   = "PrometheusRemoteStorageFailures"
    alertgroup  = "prometheus.alerts"
    asserts_env = "prod"
  }

  silenced = true
}

# High severity alert with specific job and context matching
resource "grafana_asserts_notification_alerts_config" "error_buildup_notify" {
  provider = grafana.asserts

  name = "ErrorBuildupNotify"

  match_labels = {
    alertname               = "ErrorBuildup"
    job                     = "acai"
    asserts_request_type    = "inbound"
    asserts_request_context = "/auth"
  }

  silenced = false
}
```

## Notification alerts with additional labels and duration

Configure alerts with custom labels and timing requirements:

```terraform
# Alert with additional labels and custom duration
resource "grafana_asserts_notification_alerts_config" "payment_test_alert" {
  provider = grafana.asserts

  name = "PaymentTestAlert"

  match_labels = {
    alertname         = "PaymentTestAlert"
    additional_labels = "asserts_severity=~\"critical\""
    alertgroup        = "alex-k8s-integration-test.alerts"
  }

  alert_labels = {
    testing = "onetwothree"
  }

  duration = "5m"
  silenced = false
}
```

## Latency and performance notification alerts

Monitor and alert on latency and performance issues:

```terraform
# Latency alert for shipping service
resource "grafana_asserts_notification_alerts_config" "high_shipping_latency" {
  provider = grafana.asserts

  name = "high shipping latency"

  match_labels = {
    alertname            = "LatencyP99ErrorBuildup"
    job                  = "shipping"
    asserts_request_type = "inbound"
  }

  silenced = false
}

# CPU throttling alert with warning severity
resource "grafana_asserts_notification_alerts_config" "cpu_throttling_sustained" {
  provider = grafana.asserts

  name = "CPUThrottlingSustained"

  match_labels = {
    alertname         = "CPUThrottlingSustained"
    additional_labels = "asserts_severity=~\"warning\""
  }

  silenced = true
}
```

## Infrastructure and service notification alerts

Configure alerts for infrastructure components and services:

```terraform
# Ingress error rate alert
resource "grafana_asserts_notification_alerts_config" "ingress_error" {
  provider = grafana.asserts

  name = "ingress error"

  match_labels = {
    alertname            = "ErrorRatioBreach"
    job                  = "ingress-nginx-controller-metrics"
    asserts_request_type = "inbound"
  }

  silenced = false
}

# MySQL Galera cluster alert
resource "grafana_asserts_notification_alerts_config" "mysql_galera_not_ready" {
  provider = grafana.asserts

  name = "MySQLGaleraNotReady"

  match_labels = {
    alertname = "MySQLGaleraNotReady"
  }

  silenced = false
}
```

## Resource reference

### `grafana_asserts_notification_alerts_config`

Manage Knowledge Graph notification alerts configurations through the Grafana API.

#### Arguments

| Name           | Type          | Required | Description                                                                                                                   |
| -------------- | ------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------- |
| `name`         | `string`      | Yes      | The name of the notification alerts configuration. This field is immutable and forces recreation if changed.                  |
| `match_labels` | `map(string)` | No       | Labels to match for this notification alerts configuration. Used to filter which alerts this configuration applies to.        |
| `alert_labels` | `map(string)` | No       | Labels to add to alerts generated by this notification alerts configuration.                                                  |
| `duration`     | `string`      | No       | Duration for which the condition must be true before firing (for example, '5m', '30s'). Maps to 'for' in Knowledge Graph API. |
| `silenced`     | `bool`        | No       | Whether this notification alerts configuration is silenced. Defaults to `false`.                                              |

#### Example

```terraform
resource "grafana_asserts_notification_alerts_config" "example" {
  provider = grafana.asserts

  name = "ExampleAlert"

  match_labels = {
    alertname = "HighCPUUsage"
    job       = "monitoring"
  }

  alert_labels = {
    severity = "warning"
    team     = "platform"
  }

  duration = "5m"
  silenced = false
}
```

## Best practices

Consider the following best practices when managing notification alerts with Terraform.

### Label management

- Use specific and meaningful labels in `match_labels` to ensure precise alert filtering
- Leverage existing label conventions from your monitoring setup
- Consider using `asserts_env` and `asserts_site` labels for multi-environment setups

### Silence strategy

- Use the `silenced` parameter for temporary suppression rather than deleting notification alerts configurations
- Document the reason for silencing in your Terraform configuration comments
- Regularly review silenced configurations to ensure they're still needed

### Duration configuration

- Set appropriate duration values based on your alerting requirements
- Consider the nature of the monitored condition when choosing duration
- Use consistent duration formats across similar alert types

## Validation

After applying the Terraform configuration, verify that:

- Notification alerts configurations are created in your Knowledge Graph instance
- Configurations appear in the Knowledge Graph UI under **Observability > Rules > Notify**
- Match labels correctly filter the intended alerts
- Custom labels are properly applied to generated alerts
