Consul-Terraform-Sync Status API
|
||
---
|
||
# 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](/consul/docs/nia/tasks#status-information).
|
||
|
||
If CTS is configured [for high availability](/consul/docs/nia/usage/run-ha), you can send requests to the [`/status/cluster` endpoint path](#cluster-status) on any CTS cluster member instance to receive information about the entire cluster. Calling the `status` endpoint path (without `/cluster`), however, returns a 400 error if 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](/consul/docs/nia/usage/errors-ref) for more information.
|
||
|
||
## Status for all tasks

|
||
|

||
### 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](/consul/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` |
|
||
|
||

|
||
| -------- | -------- | ------ | ------------------ | ------- |
|
||

### Response statuses
|
||
|
||
- `200`: Successfully retrieved the task status
|

|
||
|
||
### 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.

See [section below](/consul/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.
|
||

## 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](/consul/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](/consul/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 cluster 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` | list[[member](#member-objects)] | Contains a list of [member objects](#member-objects). Each object in the `members` list 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](/consul/docs/nia/configuration#high-availability-instance) reference for additional information. |
|
||
| `healthy` | boolean | Indicates the health of the service instance health. Refer to [Service Registration](/consul/docs/nia/configuration#service-registration) for additional information. |
|
||
| `id` | string | Indicates the service registration ID. Refer to [Service Registration](/consul/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. The value is set by the `service_name` field in the [Service Registration](/consul/docs/nia/configuration#service-registration) configuration. |
|
||
|
||
### 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,
|
||
"service_name": "consul-terraform-sync"
|
||
},
|
||
{
|
||
"healthy": true,
|
||
"id": "cts-03",
|
||
"leader": false,
|
||
"service_name": "consul-terraform-sync"
|
||
},
|
||
{
|
||
"healthy": true,
|
||
"id": "cts-01",
|
||
"leader": false,
|
||
"service_name": "consul-terraform-sync"
|
||
}
|
||
],
|
||
"request_id": "e1bc2236-3d0e-5f5e-dc51-164a1cf6da88"
|
||
}
|
||
``` |
