ActionTrail is a service that monitors and records the actions of your Alibaba Cloud account. ActionTrail records these actions as events. You can create a trail to deliver events to a specified Log Service Logstore or Object Storage Service (OSS) bucket. Then, you can create a historical event delivery task to deliver the events that occurred in the last 90 days to the Log Service Logstore specified for the associated trail. This way, events can be stored for a long period. You can use the advanced event query feature to query the events that occurred in multiple regions 90 days ago in the ActionTrail console.

Prerequisites

  • An Alibaba Cloud account is created. To create an Alibaba Cloud account, visit the Create Your Alibaba Cloud Account page.
  • You are authorized to use the historical event delivery task feature. To use this feature, submit a ticket or ask the sales manager to add you to the whitelist.

Step 1: Create a trail

This section describes how to create a single-account trail to deliver events to a specified Log Service Logstore.

You can also create a multi-account trail or create a trail to deliver events to a specified OSS bucket. For more information, see Create a single-account trail and Create a multi-account trail.

  1. Log on to the ActionTrail console.
  2. In the left-side navigation pane, click Trails.
  3. In the top navigation bar, select the region where you want to create a single-account trail.
    Note The region that you select becomes the home region of the trail that you want to create.
  4. On the Trails page, click Create Trail.
  5. In the Trail Basic Settings step, enter a trail name in the Trail Name field, set the Applied Regions parameter to All Regions and the Event Type parameter to All, and then click Next.
  6. In the Event Delivery Settings step, select Delivery to Log Service, select Delivery to Current Account, and then set the parameters as required.
    Parameter Description
    Logstore Region The region where the Log Service project resides.
    Project Name The name of the Log Service project. The name must be unique to an Alibaba Cloud account in a region.
    • If you select New Log Service Project, ActionTrail creates a project with the name that you specify and creates a Logstore in the project.
    • If you select Existing Log Service Project, you must select an existing project in Log Service.

      For more information about how to create a project in Log Service, see Quick start.

  7. Click Next.
  8. In the Preview and Create step, confirm the trail information and click Submit.

Step 2: Create a historical event delivery task

A trail can deliver only the events that occur after the trail is created. Therefore, you must create a historical event delivery task to deliver the events that occurred in the last 90 days before your trail is created. This ensures that all the events required for auditing are stored.

For more information about historical event delivery tasks, see Create a historical event delivery task.

  1. In the left-side navigation pane, click Historical Event Delivery Tasks.
  2. In the top navigation bar, select the region where you want to create a historical event delivery task.
    Note This region must be the same as the region where the associated single-account trail resides.
  3. On the Historical Event Delivery Tasks page, click Create Task.
  4. On the Create Task page, select the associated trail.
    Note After you select a trail, the system automatically fills in the region from which the trail delivers events, the region where the Log Service project resides, the name of the Log Service project, and the information about the Log Service Logstore.
  5. Click Confirm.
    After you create a historical event delivery task, you can view the associated trail, the scope of the historical events that can be delivered, the delivery status, the time when the task was created, and the time when the task was complete on the Historical Event Delivery Tasks page.

Step 3: Perform advanced event queries

ActionTrail provides a variety of event query methods, such as event details query, event summary query, and advanced event query. This section describes how to perform advanced event queries in the ActionTrail console.
