+# scaleway_cockpit_sources
+
+Gets information about multiple Cockpit data sources.
+
+## Example Usage
+
+### List all sources in a project
+
+```hcl
+data "scaleway_cockpit_sources" "all" {
+  project_id = "11111111-1111-1111-1111-111111111111"
+}
+```
+
+### Filter sources by type
+
+```hcl
+data "scaleway_cockpit_sources" "metrics" {
+  project_id = "11111111-1111-1111-1111-111111111111"
+  type       = "metrics"
+}
+```
+
+### Filter sources by name
+
+```hcl
+data "scaleway_cockpit_sources" "my_sources" {
+  project_id = "11111111-1111-1111-1111-111111111111"
+  name       = "my-data-source"
+}
+```
+
+### Filter sources by origin
+
+```hcl
+data "scaleway_cockpit_sources" "external" {
+  project_id = "11111111-1111-1111-1111-111111111111"
+  origin     = "external"
+}
+```
+
+### List default Scaleway sources
+
+```hcl
+data "scaleway_cockpit_sources" "default" {
+  project_id = "11111111-1111-1111-1111-111111111111"
+  origin     = "scaleway"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+- `project_id` - (Optional) The project ID the cockpit sources are associated with.
+- `region` - (Optional) The region in which the cockpit sources are located.
+- `name` - (Optional) Filter sources by name.
+- `type` - (Optional) Filter sources by type. Possible values are: `metrics`, `logs`, `traces`.
+- `origin` - (Optional) Filter sources by origin. Possible values are: `scaleway`, `external`, `custom`.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+- `sources` - List of cockpit sources.
+
+Each `sources` block contains:
+
+- `id` - The ID of the data source.
+- `name` - Name of the datasource.
+- `url` - The URL of the datasource.
+- `type` - The type of the datasource.
+- `origin` - The origin of the datasource.
+- `synchronized_with_grafana` - Indicates whether the data source is synchronized with Grafana.
+- `created_at` - The date and time of the creation of the cockpit datasource.
+- `updated_at` - The date and time of the last update of the cockpit datasource.
+- `retention_days` - The number of days to retain data.
+- `push_url` - The URL endpoint used for pushing data to the cockpit data source.
+- `region` - The region of the data source.
+- `project_id` - The project ID of the data source.
+
+## Use Cases
+
+This data source is particularly useful when you need to:
+
+- List all data sources in a project for monitoring or management purposes
+- Provision a separate Grafana instance with all available data sources
+- Iterate over multiple data sources using Terraform's `for_each` or `count` meta-arguments
+- Filter data sources by specific criteria without knowing their exact names or IDs
+
+## Example: Provisioning Grafana with all data sources
+
+```hcl
+data "scaleway_cockpit_sources" "all" {
+  project_id = "11111111-1111-1111-1111-111111111111"
+}
+
+resource "grafana_data_source" "cockpit_sources" {
+  for_each = {
+    for source in data.scaleway_cockpit_sources.all.sources : source.name => source
+  }
+  
+  type = "prometheus" # or "loki" for logs, "tempo" for traces
+  name = each.value.name
+  url  = each.value.url
+}
+```
