# Status

The `/status` endpoints return status-related information for tasks. This endpoint returns a count of successful and failed task events that are recorded whenever tasks execute an automation. Currently, only the five most recent events are stored in Consul-Terraform-Sync (CTS). For more information on the hierarchy of status information and how it is collected, refer to [Status Information](/docs/nia/tasks#status-information).

If CTS is configured [for high availability](/docs/nia/usage/run-ha), you can send a request to the [`/status/cluster` endpoint](#cluster-status) of any instance to get information about the cluster. Requests to the `status` endpoint return a 400 error, however, if high availability is enabled and the request is sent to a follower instance. The error message depends on what information the follower instance is able to obtain about the leader. Refer to [Error Messages](/docs/nia/usage/errors-ref) for more information.

## Status for all tasks

This endpoint returns the overall status information for all tasks.

| Method | Path                | Produces           |

| `GET`  | `/status` | `application/json` |

### Request parameters

No request parameters are available for this endpoint.

### Response statuses

- `200`: Successfully retrieved the status. 

### Response fields

| Name	| Type	 | Description        |
| ----- | ------ | ------------------ |
|`status` | object |  The summary count of how many tasks have a given health status value
|`status.successful` | integer | The number of tasks that have a `successful` health status.

### Example

Request:
```shell-session
$ curl localhost:8558/v1/status
```

Response:
```json
{
  "task_summary": {
    "status": {
      "successful": 28,
      "errored": 5,
      "critical": 1,
      "unknown": 0
    },
    "enabled": {
      "true": 32,
      "false": 2
    }
  }
}
```

## Task status

This endpoint returns the individual task status information for a single specified task or for all tasks.

Task health status value is determined by the success or failure of all stored [event data](/docs/nia/tasks#event) on the process of updating network infrastructure for a task. Currently only the 5 most recent events are stored per task.
 - Successful: The most recent stored event is successful.
 - Errored: The most recent stored event is not successful but all previous stored events are successful.
 - Critical: The most recent stored event is not successful and one or more previous stored events are also not successful.
 - Unknown: No event data is stored for the task.

| Method | Path                | Produces           |
| ------ | ------------------- | ------------------ |
| `GET`  | `/status/tasks/:task_name` | `application/json` |

### Request parameters

| Name	   | Required | Type	 | Description        | Default |
| -------- | -------- | ------ | ------------------ | ------- |
|`:task_name` | Optional | string | Option to specify the name of the task to return in the response. If not specified, all tasks are returned in the response.| none
|`include` | Optional | string | Only accepts the value `"events"`. Use to include stored event information in response. | none
|`status`  | Optional | string | Only accepts health status values `"successful"`, `"errored"`, `"critical"`, or `"unknown"`. Use to filter response by tasks that have the specified health status value. Recommend setting this parameter when requesting all tasks i.e. no `task` parameter is set. | none

### Response statuses

- `200`: Successfully retrieved the task status 
- `404`: Task with the given name not found 

### Response fields

The response is a JSON map of task name to a status information structure with the following fields.

| Name	      | Type	  | Description       |
| ----------- | ------ | ------------------ |
|`task_name`  | string | Name of the task as configured in CTS.
|`status`     | string | Values are `"successful"`, `"errored"`, `"critical"`, or `"unknown"`. This is determined by the success or failure of all stored events on the network infrastructure update process for the task, as described earlier.
|`enabled`    | boolean | Whether the task is enabled or not.
|`services`   | list[string] | **Deprecated in CTS 0.5.0 and will be removed in a future major release.** List of the services configured for the task.
|`providers`  | list[string] | **Deprecated in CTS 0.5.0 and will be removed in v0.8.0.** List of the providers configured for the task.
|`events_url` | string | Relative URL to retrieve the event data stored for the task.
|`events`     | list[[Event](/docs/nia/api/status#event)] | List of stored events that inform the task's status. See [section below](/docs/nia/api/status#event) for information on event data. This field is only included in the response upon request by setting the `?include=events` parameter. The relative URL for the request to include events can be retrieved from the `events_url` field.

#### Event

Event represents the process of updating network infrastructure of a task. The data is captured in a JSON structure. For more details on the scope of an event, see [Event](/docs/nia/tasks#event).

## Cluster status

The `/v1/status/cluster` API endpoint returns information about high-availability clusters and its members, such as health status and leadership. This endpoint is only supported when using CTS in [high availability mode](/docs/nia/usage/run-ha). If you call the endpoint without configuring CTS for high availability, then CTS prints an error to the console. Refer to [Error Messages](/docs/nia/usage/errors-ref) for information about CTS error messages. 

| Method | Path              | Response format    |
| ------ | ----------------- | ------------------ |
| `GET`  | `/status/cluster` | `application/json` |

### Request parameters

Currently no request parameters are offered for the overall status API.

### Request statuses

- `200`: Successfully retrieved the cluster status

### Response fields

The following table describes the responses that the `status/cluster` endpoint can send. 

| Field | Type | Description |
| --- | ---- | --- |
| `cluster_name` | string | Identifies the name of the cluster. |
| `members` | array | Contains an array of [member objects](#member-objects). Each object in the `members` array represents a CTS instance. |

#### Member objects

The following table describes the fields available for objects in the `members` array.  

| Field | Type | Description |
| --- | ---- | --- |
| `address` | string | Indicates the location of the instance. The address is only included in the response if the `high_availability.instance.address` option is configured on the leader instance. Refer to the [high availability instance configuration](/docs/nia/configuration#high-availability-instance) reference for additional information. |
| `healthy` | boolean | Indicates the health of the service instance health. Refer to [Service Registration](#/docs/nia/configuration#service-registration) for additional information. |
| `id` | string | Indicates the service registration ID. Refer to [Service Registration](#/docs/nia/configuration#service-registration) for additional information. |
| `leader` | boolean | Identifies the cluster leader. |
| `service_name` | string | Identifies the name of the service that the instance represents. Refer to [Service Registration](#/docs/nia/configuration#service-registration) for additional information. Default is `consul-terraform-sync`. |

### Example

The following command calls the `/status/cluster` endpoint:

```shell-session
$ curl –request GET http://localhost:8553/v1/status/cluster
```

The following example response shows three CTS instances. The cluster leader is `cts-02` and is advertising that its address is `cts-02.example.com`: 

```json
{
  "cluster_name": "cluster-a",
  "members": [
    {
      "address": "cts-02.example.com",
      "healthy": true,
      "id": "cts-02",
      "leader": true,
