Cloud Monitor

Getting Started

Using Event Center

The Event Center of Cloud Monitor enables you to monitor the events of various cloud products. You can use the Event Center to view the event details of integrated cloud products, and also configure custom event rules and event notification contacts. This enables you to capture critical events of cloud products in real time and promptly respond to the events. This topic uses ECS as an example to introduce how to view cloud product events and how to configure custom event rules.

Considerations

If you do not query the events of a cloud product by using the Event Center, it indicates that no events have occurred for the cloud product or that the events occurred over 30 days ago.

tip

Occurred events are saved for 30 days by default.

Step 1: Create a contact

In the left navigation bar, click Notification > Contacts.

Click Create contact.

In the Create contacts dialog box, specify the Name and Email or Phone parameters of the alert contact and then click Confirm.

After you configure the email address or phone number and create the contact, Cloud Monitor will send a verification message to the specified email address or phone number.

The following figure shows the verification message content sent to an email address. You need to click the URL to complete the verification.

Step 2: Create a contact group

When you create an alert policy, select the corresponding contact group to receive alert notifications through the contact group.

In the left navigation bar, click Notification > Contacts.

Click the Contact group tab, and then click Create contact group.

In the Create contact group dialog box, specify the Name, Description, and Select contacts parameters of the contact group and then click Confirm.

For example, the created contact group is TESTGroup01.

Step 3: Create a callback URL

In the left navigation bar, click Notification > Callback.

On the Callback address list page, click Create callback address.

On the Create callback address page, specify the following parameters and then click Confirm.

Parameter	Descriptions
Callback address name	Specify a custom name for the callback URL to identify the callback URL. Duplicate names are not allowed.
Callback address type	Select the callback URL type. Supported types include Lark, DingTalk, WeCom, and General callback address.
Callback address	Enter a publicly accessible URL and then click Test to verify the callback URL. If the callback URL returns the HTTP status code 200, it indicates that the connectivity test is successful, and the callback URL can receive alerts and event notifications. The connectivity test enforces a one query per second (QPS) limit.

Step 4: Create an event rule

In this step, you will create an event rule to monitor ECS events that are in the Create instance: In progress state. If the ECS event occurs, Cloud Monitor will send the event information to the specified alert contact or contact group through the specified alert channel.

In the left navigation bar, click Event Center > Event Rule.

On the Event Rule page, click Create event rule.

On the Create event rule page, specify the following parameters, and then click Confirm.

tip

In this example, only the required parameters are specified. You can adjust the configurations based on your business requirements.

Sections	Parameter	Descriptions	Sample value
Basic information	Name	Specify a custom name to identify the event rule.	Event rule Demo
Basic information		Description	Specify a custom description for the event rule.	The event rule is used for observing created ECS instances.
Event rule	Resource type	Specify the cloud service to be monitored.	Elastic Compute Service (ECS)
		Event name	After you specify the Resource type parameter, the page will automatically display the event drop-down list of the selected resource type. You need to manually select one or more event names.	Create instance: In progress
		Effective time	Specify the effective period of the event rule by day. Event Center only monitors whether the cloud service triggers the event rule during the specified effective period.	00:00 - 23:59
		Level	Specify the severity level of the event. Valid values: Critical, Warning, Notice.	Warning
Delivery method	Delivery channel	The system sends alert notifications through specified channels. You can select one or more of the following channels, which include Email, Phone, SMS, Alert callback, Torch Log Service, and Message Queue Kafka.	Email, Phone, and SMS
		Alert contact group	Select one or more contact groups as the recipients of alert notifications. Up to five contact groups within the same account can be selected as recipients.	TESTGroup01
		Webhook	Enter an alert callback URL or select one or more created callback URLs. You can select created webhook URLs. Up to eight webhook URLs can be selected. You can enter only one webhook URL.	http://example.com/alert
		Theme	Select a TLS topic. warning If you set the Delivery channel parameter to Torch Log Service, Cloud Monitor does not charge you for data. However, after Cloud Monitor delivers data to TLS, TLS will charge you for the data.	Topic1
		Message queue	Select a topic. warning Notifications can be delivered only to topics of Message Queue for Kafka in the China (Beijing) region. If a Kafka instance is bound to an allowlist, only the IP addresses configured in the allowlist can access the instance. Note: Do not select instances in an allowlist if you set the Delivery channel parameter to Message queue kafka. After you select an instance, do not add the instance to an allowlist. If you select a Message Queue for Kafka topic for an event rule for the first time, the user named __volcevent_xxxvolc will be automatically created on the User Management tab of the topic. Do not delete this user. Otherwise, Cloud Monitor will not be able to deliver messages to this topic.	topicA

After the event rule is created, you can view the information of the created event rule on the list on the Event Rule page. When an event of a monitored cloud product that meets the specified conditions occurs, you can receive alert notifications through email, phone calls, or SMS messages.

Step 5: View cloud product events

In the left navigation bar, click Event Center > Cloud Service Event.

On the Cloud Service Event page, specify the following parameters to query ECS events.

List description:

In Section ① in the preceding figure, query events that occurred during the time period from 2024-06-27 14:02:00 to 2024-07-05 14:02:00.

In Section ② in the preceding figure, query ECS events that are in the Start instance: In progress state.

After you configure the preceding query criteria, you can view the occurred events in Section ③.

Find a specified system event and click Details in the Actions column.

In the Event details panel, you can view detailed event information in JSON format, where the data field contains detailed information about the cloud product for which the event occurred.
