Monitor metrics for your Elastic IP Address (EIP), such as bandwidth and packet rate. By configuring threshold alerts and subscribing to abnormal event notifications, you can track EIP usage and promptly identify and resolve issues.
CloudMonitor alerts
Cloud Monitor (CMS) collects monitoring metrics for EIPs in real time and supports the following operations:
-
View monitoring charts to check the operational status of your EIPs.
-
Create threshold alert rules to receive timely notifications about abnormal metrics and take prompt action.
If a RAM user needs to view EIP monitoring data, you must first grant them the necessary permissions using your Alibaba Cloud account.
-
Method 1: Attach a system policy that includes the
cms:QueryMetricListpermission to the RAM user.Available system policies: AliyunCloudMonitorFullAccess, AliyunCloudMonitorMetricDataReadOnlyAccess, AliyunCloudMonitorReadOnlyAccess, and AliyunCloudMonitorReadOnlyBasicAccess.
-
Method 2: Create or modify a custom policy to include the
cms:QueryMetricListaction in an Allow statement, and then attach the custom policy to the RAM user.

View EIP monitoring
Console
-
Go to the Elastic IP Addresses console, click the ID of the target EIP, and then click the tab to view the monitoring charts.
-
By default, the console displays monitoring data from the last hour. You can view data from the last 3 hours, 6 hours, or 12 hours, or select a custom time range. You can query data from up to the last 31 days.
-
Enable Auto Refresh to update the monitoring charts every minute.
-
-
Go to the CloudMonitor console - Elastic IP Address page. Find the target EIP and click Monitoring Charts in the Actions column to view its monitoring data.
-
By default, the console displays monitoring data from the last hour. You can view data from the last 3 hours, 6 hours, 12 hours, 1 day, 3 days, 7 days, or 14 days, or select a custom time range. You can query data from up to the last 31 days.
-
API
Call the DescribeMetricList operation to query the monitoring data of a specified metric for a specified cloud service.
Create threshold alert rules
When an EIP is released, its CloudMonitor threshold alert rules are also deleted.
Console
Go to the CloudMonitor console - Alert Rules page and click Create Alert Rule.
-
Product: Select Elastic IP Address.
-
Resource Range: After an alert rule is created, its resource range cannot be modified. You can select All Resources to apply the rule to all instances of the selected Product under your account. Alternatively, you can select Instances and specify Related Resource to apply the rule only to specific instances.
-
Set rule conditions: Define the specific conditions that trigger an alert.
-
Click Add Rule and select a metric type from the drop-down list.
-
In the Configure Rule Description panel, configure the Rule Name, Metric Type, and Metric.
-
-
Mute Period: The interval between alert notifications for an unresolved issue.
-
Effective Period: The period during which the alert rule is active and checks monitoring data.
-
Alert Contact Group: The contact group to which alert notifications are sent.
API
Call the PutResourceMetricRules operation to create multiple threshold alert rules for specified metrics of a resource.
Fine-grained monitoring
If the public bandwidth usage of an EIP reaches 100% and you do not promptly scale up its bandwidth, traffic throttling and packet loss may occur. This can degrade client access quality and user experience. The fine-grained monitoring feature for EIPs offers the following benefits:
-
Increases monitoring granularity to the second level. This allows you to monitor traffic fluctuations in real time, helping you promptly adjust the EIP bandwidth peak to prevent access latency caused by bandwidth throttling.
-
Fine-grained monitoring is built on Alibaba Cloud Simple Log Service (SLS), which provides comprehensive log storage, reporting, and alerting features for second-level monitoring.
-
After you enable fine-grained monitoring, the system automatically sets the data retention period of the associated Logstore to 7 days.
-
Each Alibaba Cloud account receives a free quota of 500 MB per month. Usage that exceeds this quota incurs fees.
-
When an EIP is associated with an ECS instance or an elastic network interface, bandwidth is throttled at the network interface level of the ECS instance. The metrics for packets dropped due to this throttling are not collected by the fine-grained monitoring feature for EIPs. Therefore, you cannot view packet drop data for EIPs that are associated with ECS instances or elastic network interfaces. This data is available only for EIPs that are associated with a NAT gateway or a Server Load Balancer (SLB) instance.
Monitoring data
-
The peak outbound and inbound traffic bandwidth per second for the EIP. Unit: Bps (Bytes per second).
-
The number of packets sent and received per second by the EIP. Unit: pps.
-
The number of packets dropped per second for outbound and inbound traffic of the EIP. Unit: pps.
-
The number of new TCP connections established per second for outbound and inbound traffic of the EIP. Unit: cps (connections per second).
Enable fine-grained monitoring
Console
-
Go to the VPC console - Internet Tool Kit page and click Fine-grained Monitoring.
-
If you have not granted the required permissions for fine-grained monitoring, follow the on-screen instructions to authorize access.
-
If a RAM user needs to enable fine-grained monitoring, you must first grant them the necessary permissions using an Alibaba Cloud account.
-
-
Find the target EIP and click Enable Fine-grained Monitoring in the Actions column. Select an existing log project and Logstore, or create new ones to complete the log configuration.
-
After you enable the feature, click the
icon in the Monitor column for the target EIP to view and analyze the monitoring data.
API
Call the SetHighDefinitionMonitorLogStatus operation to enable or disable fine-grained monitoring for an EIP.
Abnormal events
EIP is integrated with the Event Center of Network Intelligence Service (NIS). You can view abnormal events that occurred on your EIP within the last 30 days to identify potentially affected resources and make timely business adjustments.
-
After an EIP is associated with a cloud resource, you can view abnormal events for the EIP on the tab of the target EIP's details page.
-
You can view all abnormal events that occurred within the last 30 days.
-
After you view an event, you can follow the recommended actions to resolve it.
-
Subscribing to events allows you to receive alert notifications for critical events, enabling you to make prompt business adjustments.
