This topic describes the FAQ about the Monitor service.

What can I do if I do not want to receive alerts for a node?

After you create and enable a monitoring baseline, the Monitor service monitors all nodes in the baseline and their ancestor nodes. If a node in the baseline or an ancestor node of the baseline affects data generation by the monitored nodes in the baseline, the Monitor service reports an alert to the node owner. For more information, see Monitor.1
As shown in the preceding figure, assume that DataWorks has only six nodes, and Nodes D and E belong to a monitoring baseline. The Monitor service monitors Nodes D and E and all their ancestor nodes. That is, the Monitor service will detect any error or slowdown on Node A, B, D, or E. Nodes C and F are not monitored by the Monitor service.
  • If the owners of Nodes D and E do not want to receive alerts, contact the baseline owner to remove Nodes D and E from the baseline.
  • Nodes A and B are ancestor nodes of Nodes D and E and may affect data generation by the monitored nodes in the baseline. When an error or slowdown occurs on Node A or B, the Monitor service reports an alert to the node owner.

    If the owner of Node A or B does not want to receive alerts, contact the owners of Nodes D and E to delete the dependency of Nodes D and E on Node A or B.

What can I do if I fail to receive SMS or email alert notifications after I configure alert notification in Operation Center?

If you specify an incorrect mobile number or email address for receiving alert notifications, the system sends alert notifications to the recipients listed on the Common Settings page. The specified alert recipient does not receive the alert notifications.

To resolve this issue, follow these steps:
  1. Log on to the DataWorks console.
  2. In the left-side navigation pane, click Workspaces.
  3. On the Workspaces page that appears, find the target workspace and click Data Analytics in the Actions column.
  4. On the page that appears, click the username in the upper-right corner and select User Info.
  5. On the Personal Account page, check whether the email address and mobile number are correct. You can change the email address and mobile number as prompted.
    Notice You can only change the email address and mobile number of a Resource Access Management (RAM) user under your Alibaba Cloud account.

Why is no alert reported for a baseline in the Overtime state?

Baseline monitoring is controlled by the baseline switch and enabled for nodes. If all nodes are running normally, no alert will be triggered even in the Overtime state. This is because all the nodes are running normally and the Monitor service cannot determine which node has an error. Overtime is a baseline status, indicating that a node is still not completed after the committed time.

The reasons why the baseline still enters the Overtime state when all nodes are normal are as follows:
  • The baseline time is set improperly.
  • The node dependency is incorrect.

Can I disable the Monitor service from reporting an alert for a node that slows down?

The Monitor service reports a node slowdown alert only when a node meets both the following conditions:
  • The node is an ancestor node of an important baseline.
  • Compared with its historical performance, the node does slow down.
You can view the descendant baseline affected by the node on the Event Management page. Then, you can confirm the impact with the party whose monitoring baseline contains descendant nodes of your node.
  • If the node slowdown has a minor impact, you can ignore the alert.
  • If the node slowdown has a major impact, maintain your node properly.

Why do I fail to receive an alert for an error node?

The Monitor service reports an alert only for specified nodes when an error occurs. An alert is reported for an error node only when the node meets one of the following conditions:
  • The node is an ancestor node of a baseline that has been enabled.
  • An alert trigger has been customized.

What can I do if I receive an alert at night?

If you receive an alert at night, go to the Event Management page to disable the event alert. However, the alert can only be disabled for a period of time. After you receive an alert, you need to handle it in a timely manner.
