Background

TDSQL for MySQL upgraded the monitoring items for server and component services on April 1, 2021 by replacing the legacy alarm policy type and modifying hundreds of monitoring and alarm metrics. You can configure alarm policies of the TDSQL for MySQL type in the Cloud Monitor console.

The legacy TDSQL policy type was deactivated on July 29, 2021. You cannot configure new alarm policies in this type any more, and your previously configured TDSQL alarm polices will be gradually transferred to the new policy type.

Comparison of the legacy and new alarm policy types:

Note：

• The new TDSQL for MySQL policy type has covered all metrics of the legacy TDSQL policy type. For more information, please see Comparison Table of New and Legacy Metrics.
• For the new alarm policies, please see New Metric Description.

Alarm Policy Migration

After the legacy TDSQL policy type is deactivated, the system will automatically transfer previously configured alarm policies to the new TDSQL for MySQL policy type on the backend.

Note：

Alarms may not be automatically transferred to the new alarm policy type by the system for certain instances or users. If this is the case for you, we will notify you through Message Center, email, or SMS. Then, please follow the manual transfer steps below to manually transfer the alarms.

Manual transfer steps

1. Sort out exiting alarm metrics and policies.
   1. Log in to the Cloud Monitor console, select Alarm Configuration > Alarm Policy on the left sidebar, and click Advanced Filter.
   2. On the pop-up page, select the alarm policy type corresponding to Tencent Distributed SQL in Policy Type, query alarm policies in this category, and download the previously configured alarm policies of the original Tencent Distributed SQL policy type.
      
2. Configure new alarm policies.
   1. On the Alarm Policy page, click Create.
   2. On the Create Alarm Policy page, select Cloud Database - TDSQL MySQL - Instance for Policy Type and configure alarms according to the policies downloaded in step 1. For the alarm configuration method, please see Creating Alarm Policy.
3. Verify whether the TDSQL for MySQL alarm policies are enabled and can successfully trigger alarms.
   Set a minimum trigger threshold in Metric alarm on the Create Alarm Policy page, choose to set a recipient or recipient group, and select the notification channel (email or SMS) to test a policy. For example, you can configure an alarm policy for the CPU utilization metric that triggers an alarm once per minute when the threshold is greater than or equal to 1% for one statistical period of one minute.
4. After the new policy type is verified, delete the alarm policies previously configured under the original TDSQL (legacy) policy type.
   On the Alarm Policy page, filter alarm policies by the "Tencent Distributed SQL" policy type and delete the filtered policies according to the policy list downloaded in step 1.
   If you encounter any issues during the transfer, please submit a ticket for assistance.
