Notebook Cache Directory Alarm Reporting

When creating a notebook instance, you can select CPU, GPU, or Ascend resources based on the service data volume. If you select GPU or Ascend resources, ModelArts mounts hard disks to the cache directory. You can use this directory to store temporary files.

Capacity alarms are not generated for the cache directory of the notebook instance by default. Exceeding the capacity limit will restart the notebook instance. After the restart, multiple configurations are reset, discarding your data and losing the environment. This will affect your experience. You are advised to enable the monitoring and alarms for the cache directory usage and report the data to AOM.

      4. Click Add Subscription in the Operation column of the topic. After the subscription is successful, a notification is received once the alarm conditions are met.

        Select a protocol, such as email or SMS, and enter the endpoints, such as email addresses or mobile numbers. Click OK.

        A record is displayed in the subscription list, but the record is in the Unconfirmed state.

        After receiving the email, confirm the subscription.

        Then, the subscription is in the confirmed state.

    • Creating an Alarm Action Rule

      An action rule specifies how AOM notifies you when an alarm is triggered. After an alarm action rule is enabled, the system sends notifications based on the associated SMN topic and message template.

      Enter the action rule name, select the action rule type, select the topic created in the previous step, select a message template, and click Confirm.

      Figure 6 Create Alarm Action Rule

In the Alarm Notification area of the Create Alarm Rule page, set Action Rule to the newly created alarm action rule and click Create Now.

After the configuration is complete, you will receive an email notification once the alarm conditions are met.
