# Troubleshooting a task run which stopped responding

When your Job task stopped responding, get the observability metrics to identify causes.

## Procedure

1. Get the ID of the task run to be analyzed.

   This ID is available on the Task execution log page in Talend Management Console, reading as Task execution ID. Or you can obtain this ID via a GET call from the /processing/executables/tasks/{taskId}/executions endpoint.

   The task ID is available on the Task details page in Talend Management Console. If you need to get this ID via API, follow [Getting tasks for which you need update the artifact version](https://help.qlik.com/talend/r/en-US/Cloud/use-api-to-update-artifact-in-tasks/get-tasks-to-be-updated).
2. Issue the following API request to find the components that are still running:
   ```
   method: GET
   endpoint:
         https://api.<env>.cloud.talend.com/monitoring/observability/executions/{runId}/component
   headers: {
    "Authorization": "Bearer <personanl_access_token>"
   }
   payload: N/A
   ```
3. Analyze the response to identify the component for which the component\_execution\_duration\_milliseconds field is not available.
4. Issue another API request to find which components handles the most records:
   ```
   method: GET
   endpoint:
      https://api.<env>.cloud.talend.com/monitoring/observability/executions/{runId}/component?sortBy=component_connection_rows_total&sortOrder=desc
   headers: {
    "Authorization": "Bearer <personanl_access_token>"
   }
   payload: N/A
   ```
5. Issue this API request to find which component runs for the longest time:
   ```
   method: GET
   endpoint:
      https://api.<env>.cloud.talend.com/monitoring/observability/executions/{runId}/component?sortBy=component_execution_duration_milliseconds&sortOrder=desc
   headers: {
    "Authorization": "Bearer <personanl_access_token>"
   }
   payload: N/A
   ```

## Results

* By component name, you can tell whether some of the components you identified above are connection components, for example, tMongoDBConnection. If they are, the issue could lie in connection.
* Examine the health status of the Cloud engine where your task was run.
* Read information about these components in the log of this task run. You can read this log either on the Run overview page in Talend Management Console or via API, as explained in [Getting a task run log for live monitoring](https://talend.qlik.dev/use-cases/monitoring-tasks/monitor-task-runs-live/).

Below is an example of the response of the GET request at /monitoring/observability/executions/{runId}/component.
