+# Data Source: scaleway_cockpit_preconfigured_alert
+
+Gets information about preconfigured alert rules available in Scaleway Cockpit.
+
+Preconfigured alerts are ready-to-use alert rules that monitor common metrics for Scaleway services.
+You can enable these alerts in your Alert Manager using the `scaleway_cockpit_alert_manager` resource.
+
+For more information, refer to Cockpit's [product documentation](https://www.scaleway.com/en/docs/observability/cockpit/concepts/) and [API documentation](https://www.scaleway.com/en/developers/api/cockpit/regional-api).
+
+## Example Usage
+
+### Basic usage
+
+```terraform
+data "scaleway_cockpit_preconfigured_alert" "main" {
+  project_id = scaleway_account_project.project.id
+}
+
+output "available_alerts" {
+  value = data.scaleway_cockpit_preconfigured_alert.main.alerts
+}
+```
+
+### Filter by status
+
+```terraform
+data "scaleway_cockpit_preconfigured_alert" "enabled" {
+  project_id  = scaleway_account_project.project.id
+  rule_status = "enabled"
+}
+
+data "scaleway_cockpit_preconfigured_alert" "disabled" {
+  project_id  = scaleway_account_project.project.id
+  rule_status = "disabled"
+}
+```
+
+### Use with Alert Manager
+
+```terraform
+resource "scaleway_account_project" "project" {
+  name = "my-observability-project"
+}
+
+resource "scaleway_cockpit" "main" {
+  project_id = scaleway_account_project.project.id
+}
+
+data "scaleway_cockpit_preconfigured_alert" "all" {
+  project_id = scaleway_cockpit.main.project_id
+}
+
+resource "scaleway_cockpit_alert_manager" "main" {
+  project_id = scaleway_cockpit.main.project_id
+  
+  # Enable specific alerts by their preconfigured_rule_id
+  preconfigured_alert_ids = [
+    for alert in data.scaleway_cockpit_preconfigured_alert.all.alerts :
+    alert.preconfigured_rule_id
+    if alert.product_name == "instance" && alert.rule_status == "disabled"
+  ]
+
+  contact_points {
+    email = "[email protected]"
+  }
+}
+```
+
+## Argument Reference
+
+- `project_id` - (Optional) The ID of the project the alerts are associated with. If not provided, the default project configured in the provider is used.
+- `region` - (Optional, defaults to provider region) The region in which the alerts exist.
+- `data_source_id` - (Optional) Filter alerts by data source ID.

+  - `annotations` - Map of annotations attached to the alert.
+  - `preconfigured_rule_id` - Unique identifier of the preconfigured rule. Use this ID in `scaleway_cockpit_alert_manager` resource.
+  - `display_name` - Human-readable name of the alert.
+  - `display_description` - Human-readable description of the alert.
+  - `product_name` - Scaleway product associated with the alert (e.g., "instance", "rdb", "kubernetes").

+# Cockpit Alert Manager Migration Guide
+
+This guide explains how to migrate from the deprecated `enable_managed_alerts` field to the new `preconfigured_alert_ids` field in the `scaleway_cockpit_alert_manager` resource.
+
+## Background
+
+The `enable_managed_alerts` field is being deprecated in favor of a more flexible approach using `preconfigured_alert_ids`. This change provides:
+
+- **Granular control**: Select specific alerts instead of enabling all managed alerts
+- **Better visibility**: Explicitly declare which alerts are enabled in your Terraform configuration
+- **Improved state management**: Terraform accurately tracks which alerts are active
+
+## Migration Steps
+
+### Before Migration (Deprecated)
+
+```terraform
+resource "scaleway_cockpit_alert_manager" "main" {
+  project_id            = scaleway_account_project.project.id
+  enable_managed_alerts = true
+
+  contact_points {
+    email = "[email protected]"
+  }
+}
+```
+
+### After Migration (Recommended)
+
+#### Step 1: List Available Preconfigured Alerts
+
+Use the data source to discover available alerts:
+
+```terraform
+data "scaleway_cockpit_preconfigured_alert" "all" {
+  project_id = scaleway_account_project.project.id
+}
+
+output "available_alerts" {
+  value = data.scaleway_cockpit_preconfigured_alert.all.alerts
+}
+```
+
+Run `terraform apply` and review the output to see available alerts.
+
+#### Step 2: Select Specific Alerts
+
+Choose the alerts you want to enable:
+
+```terraform
+resource "scaleway_cockpit_alert_manager" "main" {
+  project_id = scaleway_account_project.project.id
+
+  # Enable specific alerts by product/family
+  preconfigured_alert_ids = [
+    for alert in data.scaleway_cockpit_preconfigured_alert.all.alerts :
+    alert.preconfigured_rule_id
+    if contains(["PostgreSQL", "MySQL"], alert.product_name)
+  ]
+
+  contact_points {
+    email = "[email protected]"
+  }
+}
+```
+
+Or use specific alert IDs:
+
+```terraform
+resource "scaleway_cockpit_alert_manager" "main" {
+  project_id = scaleway_account_project.project.id
+
+  preconfigured_alert_ids = [
+    "6c6843af-1815-46df-9e52-6feafcf31fd7", # PostgreSQL Too Many Connections
+    "eb8a941e-698d-47d6-b62d-4b6c13f7b4b7", # MySQL Too Many Connections
+  ]
+
+  contact_points {
+    email = "[email protected]"
+  }
+}
+```
+
+## Filtering Alerts
+
+### By Product Name
+
+```terraform
+preconfigured_alert_ids = [
+  for alert in data.scaleway_cockpit_preconfigured_alert.all.alerts :
+  alert.preconfigured_rule_id
+  if alert.product_name == "Kubernetes"
+]
+```
+
+### By Product Family
+
+```terraform
+preconfigured_alert_ids = [
+  for alert in data.scaleway_cockpit_preconfigured_alert.all.alerts :
+  alert.preconfigured_rule_id
+  if alert.product_family == "Managed Databases"
+]
+```
+
+### Multiple Criteria
+
+```terraform
+preconfigured_alert_ids = [
+  for alert in data.scaleway_cockpit_preconfigured_alert.all.alerts :
+  alert.preconfigured_rule_id
+  if alert.product_family == "Load Balancer" && alert.product_name == "LB"
+]
+```
+
+## Important Notes
+
+### Behavioral Changes
+
+- **No automatic alerts**: Unlike `enable_managed_alerts = true`, the API will not automatically enable additional alerts
+- **Explicit configuration**: You must explicitly list all alerts you want to enable
+- **State accuracy**: Terraform state will only track alerts you've configured
+
+### Compatibility
+
+- The deprecated `enable_managed_alerts` field will be removed in a future major version
+- Both fields can coexist during migration, but `preconfigured_alert_ids` takes precedence
+- If neither field is specified, no preconfigured alerts will be enabled
+
+## Troubleshooting
+
+### "Insufficient permissions" Error
+
+If you see permission errors when using the `scaleway_cockpit_preconfigured_alert` data source, ensure your IAM policy includes:
+
+```json
+{
+  "permission_sets": [
+    {
+      "name": "CockpitManager",
+      "permissions": [
+        "read:cockpit"
+      ]
+    }
+  ]
+}
+```
+
+### Unexpected State Changes
+
+If Terraform shows unexpected changes to `preconfigured_alert_ids`:
+
+1. Verify the alert IDs still exist by querying the data source
+2. Check that alerts are in `enabled` or `enabling` state
+3. Ensure no manual changes were made outside Terraform
