This topic describes the FAQ about the Monitor service.
- What can I do if I do not want to receive alerts for a node?
- What can I do if I fail to receive SMS or email alert notifications after I configure alert notification in Operation Center?
- Why is no alert reported for a baseline in the Overtime state?
- Can I disable the Monitor service from reporting an alert for a node that slows down?
- Why do I fail to receive an alert for an error node?
- What can I do if I receive an alert at night?
What can I do if I do not want to receive alerts for a node?

- 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.
- Log on to the DataWorks console.
- In the left-side navigation pane, click Workspaces.
- On the Workspaces page that appears, find the target workspace and click Data Analytics in the Actions column.
- On the page that appears, click the username in the upper-right corner and select User Info.
- 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 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 node is an ancestor node of an important baseline.
- Compared with its historical performance, the node does slow down.
- 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 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.
