Drill Tasks

Creating a Drill Task

Create a drill task on COC.

Procedure - Creating a Drill Task

1. Log in to COC.
2. In the navigation pane on the left, choose Resilience Center > Chaos Drill and click Drill Tasks.
3. Click Create Task. Or you can accept a drill plan to access the page for creating a drill task by following the instructions in Drill Plan.

4. Enter the basic information about the drill task, including the drill task name and expected recovery duration (in minutes).
   Figure 2 Basic information of a drill task
   

5. Select an attack task. By default, there is one attack task group. You can click Create Task Group to add a task group or click Create Attack Task to access the page for creating an attack task.
   Figure 3 Selecting an attack task
   

6. Add an attack task. You can create an attack task or select an existing attack task. If you have not created an attack task before, you need to click Create Attack Task. However, if you have created attack tasks previously, you can select Select from Existing.
7. Create an attack task. First, select an attack target, and then select an attack scenario. Different attack targets correspond to different attack scenarios. Enter the attack task name. The attack target sources include Elastic Cloud Server (ECS) or Cloud Container Engine (CCE), Cloud Database (RDS), and Distributed Cache Service (DCS). If you select ECS, you will need to select the corresponding server from the list below and click Next.

8. Select an attack scenario, set attack parameters, and click OK. The scenarios include Host Resource, Host Process, and Host Network.
   Figure 5 ECS attack scenarios
   

9. (Optional) Configure drill monitoring task metrics that include Stable-Status Metrics and Monitoring Metrics. You can specify the host in the attack target and the name of the metric to be monitored. During the drill, you can view the real-time drill line chart of the corresponding metric.

Editing a Drill Task

You can edit a drill task. However, if a drill record has been generated for the drill task, the task cannot be edited.

Procedure - Editing a Drill Task

1. Log in to COC.
2. In the navigation pane on the left, choose Resilience Center > Chaos Drill and click Drill Tasks.
3. Choose More > Edit in the Operation column to modify the basic information about the drill task.
   Figure 16 Locate the target task, click Modify in the Operation column.
   

4. You can add a task group, add an attack task, or delete an existing attack task. An existing attack task cannot be modified.
5. Click OK.

Deleting a Drill Task

Delete a created drill task. A task that has generated drill records or has associated with drill plans cannot be deleted.

Procedure - Deleting a Drill Task

1. Log in to COC.
2. In the navigation pane on the left, choose Resilience Center > Chaos Drill and click Drill Tasks.
3. Locate the target drill task, choose More > Delete in the Operation column.

Starting a Drill Task

Start a drill task.

Procedure - Starting a Drill Task

1. Log in to COC.
2. In the navigation pane on the left, choose Resilience Center > Chaos Drill and click Drill Tasks.
3. Locate the target drill task, click Start Drill in the Operation column.
   Figure 20 Starting a drill task
   

4. Click Drill Record in the Operation column to view the attack progress, including probe installation, drill execution, and environment clearance. The system automatically executes the drill task. The execution time depends on the attack time of the weapon.

5. During the drill task execution, you can click Terminate Drill to end the drill task, click Retry to retry the current step, or click Skip to skip the current step and go to the next step. If you have configured a drill monitoring task when creating the attack task, you can click Monitor to view the real-time monitoring data of the attack target.

Viewing Drill Records

View the drill records of a drill task. A drill task that has not been drilled does not contain drill record.

Procedure - Viewing Drill Records

1. Log in to COC.
2. In the navigation pane on the left, choose Resilience Center > Chaos Drill and click Drill Tasks.
3. Locate the target drill task, click Drill Record in the Operation column.
   Figure 25 Drill task list
   

4. The basic information about the drill task includes the drill task name, drill task ID, attack details, and failure mode. All drill records include the drill record ID, execution status, executor, drill start time, and drill end time.
