Global Accelerator:Monitoring and alerting

Last Updated:Apr 01, 2026

Global Accelerator (GA) integrates with Cloud Monitor (CMS) to provide real-time visibility into instance performance, so you can quickly detect and respond to issues such as request timeouts, traffic throttling, and packet loss.

GA supports three monitoring paths:

PathBest forHow to access
GA console monitoring chartsViewing time series charts for bandwidth, packets, connections, and CU usageGA console > instance > Monitoring Chart tab
CloudMonitor alert rulesGetting notified when a metric crosses a thresholdCloudMonitor console > Alerts > Alert Rules
CloudMonitor APIQuerying origin probing availability and tunnel latencyCloudMonitor API operations

View monitoring data

Cloud Monitor collects metrics from GA instances in real time and renders them as time series charts in the GA console. The default time range is the previous hour. Other supported ranges are 3 hours, 6 hours, 12 hours, and a custom range. Turn on Auto Refresh to refresh the chart every minute.

View monitoring data for a standard GA instance

  1. Log on to the GA console.

  2. On the Instances page, find the GA instance and open the monitoring panel using one of the following methods:

    • From the Instances page: In the Monitor/Diagnostics column, click the 监控 icon. The Instance Monitoring panel opens.

    • From the instance details page: Click the instance ID, then click the Monitoring Chart tab.

  3. Filter the monitoring data as needed:

    • To view acceleration region or endpoint region metrics, choose Instance > Acceleration Region or Instance > Endpoint Region, then select a region from the Region drop-down list.

    • To view CU consumption, choose Instances > Used CUs. This applies to pay-as-you-go standard GA instances.

    • To view listener metrics, click Listener. This applies to pay-as-you-go standard GA instances.

    • To select a time range, use the Time drop-down list.

  4. To create an alert rule directly from this view, click Threshold Alerting Settings. This opens the Alert Rules page in the CloudMonitor console.

If you cannot view the monitoring metrics of intelligent routing listeners on your pay-as-you-go standard GA instance, the instance may be running an earlier version. Contact your account manager to upgrade.

View monitoring data for a basic GA instance

  1. Log on to the GA console.

  2. In the left-side navigation pane, click Basic Instance.

  3. On the Instances page, find the GA instance and open the monitoring panel using one of the following methods:

    • From the Instances page: In the Monitor column, click the 监控 icon. The Instance Monitoring panel opens.

    • From the instance details page: Click the instance ID, then click the Monitoring Chart tab.

  4. Filter the monitoring data as needed:

    • In the Granularity drop-down list, select Acceleration Region or Accelerated IP.

    • If you select Accelerated IP, choose up to three accelerated IP addresses to compare.

    • To select a time range, use the Time drop-down list.

Create a threshold-triggered alert rule

Set up alert rules to get notified when a GA metric crosses a threshold, so you can respond before issues affect users.

If a GA instance is deleted, all threshold-triggered alert rules configured for it in CloudMonitor are also deleted.
  1. Log on to the Cloud Monitor console.

  2. In the left-side navigation pane, choose Alerts > Alert Rules.

  3. On the Alert Rules page, click Create Alert Rule.

  4. In the Create Alert Rule panel, configure the following parameters and click Confirm. For parameters not listed here, see Create an alert rule.

    ParameterDescription
    ProductSelect Global Accelerator - Basic GA Instance or Global Accelerator - Standard GA Instance.
    Resource RangeSelect the scope of resources the alert applies to: All Resources (all GA instances in the account), Application Groups (all resources in a specified application group), or Instances (a specific GA instance). If you select Application Groups or Instances, choose the application group or instance from the Associated Resources drop-down list.
    Rule DescriptionDefine the alert condition. Click Add Rule, configure the Alert Rule, Metric Type, Metric, and Threshold and Alert Level parameters in the Configure Rule Description panel, then click OK. For supported metrics, see Supported metrics.
Threshold Alerting Settings in the GA console applies to standard GA instances only. To configure alert rules for basic GA instances, go directly to the CloudMonitor console.

Supported metrics

Use the following guidance to map symptoms to the relevant metrics before querying the tables below.

Common diagnostic scenarios:

  • High bandwidth usage or throttling: Check GaIpOutBpsPercentage or GaIpInBpsPercentage to see how much of the bandwidth cap you are consuming. High values indicate you may need to increase bandwidth.

  • Packet loss: Check GaIpOutDropPps or GaIpInDropPps. Sustained non-zero values indicate traffic is being discarded, often due to bandwidth throttling.

  • Connection spikes: Check GaIpCPS (new connections per second) and GaIpActiveConnectionCount (established connections) together to identify sudden load increases.

  • HTTP/Layer 7 request rates: Check GaListenerQPS on listener metrics (pay-as-you-go standard GA only).

  • Origin health and tunnel latency: Query GaApplicationMonitorAvailability and GaTunnelLatency via CloudMonitor API. These metrics are not available in the console.
