Configure monitoring and alerting in CloudMonitor

DataHub supports the monitoring and alerting features of CloudMonitor. You can create alert rules to configure monitoring and alerting for DataHub metrics. Only the metric of subscription latency is supported.

Create a threshold-triggered alert rule

CloudMonitor can send alert notifications by means of phone calls, text messages, TradeManager messages, emails, or DingTalk chatbots. If you want to receive alert notifications based on multiple methods, make sure that the contact information specified for these methods is correct.

Log on to the CloudMonitor console.
In the left-side navigation pane, choose Alerts > Alert Rules.
On the Alert Rules page, click Create Alert Rule.
On the Create Alert Rule page, specify the subscriptions to be monitored. Then, you can view the metric of subscription latency in the Set Alert Rules section. You must also configure alert rules and notification methods.

5.After the alert rule is created, you can view the details of the alert rule, alert history, and the status of the alert rule. You can also modify or disable the alert rule. If you set the notification method to text messages, alert text messages are sent to the specified phone number after the alert rule is triggered.
