Creating event rules

To quickly identify any abnormal occurrences, you can set up alert rules to receive notifications through the specified channel when certain events occur in your TOS bucket. This topic explains how to do that.

Prerequisites

You have either created contracts and associated them with a contact group, or created a callback URL. For more information, see Creating contacts and Create a callback URL.

Steps

In the left navigation pane, select Event Center > Event rule.

On the Event rule page, click Create event rule.

On the Create event rule page, configure the following parameters.

Parameter	Description
Name	Enter the name of the event rule. Naming rules: The rule name must be between 1 and 128 characters long. The rule name cannot start with a number or a hyphen (-).
Description	Provide additional information about the event rule.
Resource type	Select object storage.
Event name	Select the event types you want to monitor. For a list of supported event types for TOS, see Throttling event metrics.
Severity level	Specify the severity level of the event. The options are Critical, Warning, and Notification.
Project selection	Select the project(s) to which the resources that you want to monitor belong. The options are All projects or Partial projects.
Match by event details	(Optional) Use this to further filter the alert scope based on the TOS event's detailed fields. Click Add to configure matching conditions using fields after data., such as "bucket name", "object name", "request source", or "error code". For example, to receive alerts only for a particular bucket, set data.bucketName = example-bucket.
Notification policy	Select a notification policy after an alert is triggered. A notification policy specifies who will receive notifications and how they will be delivered. Supported notification methods include phone, SMS, email, Feishu, WeCom, DingTalk, Slack, callback URL, orchestration, Torch Log Service, and Message Queue for Kafka. If the default policy does not meet your needs, you can create a custom notification policy. For more information, see Creating a notification policy.

Once you have finished configuring, click Confirm.

Event rules are enabled by default once created. You can change an event rule's status where necessary. For instructions, see Managing event rules.
