If you encounter network connection issues, such as request timeout and traffic throttling, when you use Global Accelerator (GA) or you want to analyze the load and performance of a GA resource, you can use Cloud Monitor (CMS) to view the status and metrics of GA resources and identify issues in an efficient manner.
View the monitoring information of a GA instance
Cloud Monitor collects monitoring metrics from GA in real time and generates visualized time series charts in the GA console. You can troubleshoot issues based on the collected metrics.
View the monitoring data of a standard GA instance
Log on to the GA console.
On the Instances page, find the GA instance that you want to manage and use one of the following methods to view the monitoring data:
On the Instances page
In the Monitor/Diagnostics column, click the
icon. In the Instance Monitoring panel, view the monitoring information.
On the instance details page
Click the ID of the GA instance.
On the instance details page, click the Monitoring Chart tab to view the monitoring information.
You can perform the following operations to filter monitoring information based on the metric type, region, and time range, or create threshold-triggered alert rules. For more information about the monitoring metrics supported by standard GA instances, see Metrics of standard GA instances.
Select the type of the metric that you want to view.
Choose or and select a region from the Region drop-down list.
Choose to view the number of CUs consumed by a pay-as-you-go standard GA instance.
Click to view the monitoring metrics of the listener added to the pay-as-you-go standard GA instance.
NoteIf you cannot view the monitoring metrics of intelligent routing listeners of your pay-as-you-go standard GA instance, the instance may be using an earlier version. Contact your account manager to upgrade your GA instance.
In the Time drop-down list, select a time range.
By default, the system displays the monitoring data collected within the previous hour. You can select other time ranges from the Time drop-down list. The supported time ranges are 3 hours, 6 hours, and 12 hours. You can also specify a custom time range.
Click Threshold Alerting Settings. On the Alert Rules page of the CloudMonitor console, click Create Alert Rule to create an alert rule for the GA instance. Threshold Alerting Settings is supported only by standard GA instances. To configure alert rules for basic GA instances, go to the CloudMonitor console. For more information, see Create a threshold-triggered alert rule.
If you turn on Auto Refresh, the monitoring chart is automatically refreshed every minute.
View the monitoring data of a basic GA instance
Log on to the GA console.
In the left-side navigation pane, click Basic Instance.
On the Instances page, find the Global Accelerator instance that you want to manage and use one of the following methods to view the monitoring data:
On the Instances page
Click
in the Monitor column In the Instance Monitoring panel, view the monitoring information.
On the instance details page
Click the ID of the GA instance.
On the instance details page, click the Monitoring Chart tab to view the monitoring information.
You can perform the following operations to filter monitoring data by monitoring granularity and time range. For more information about the monitoring metrics supported by basic Global Accelerator instances, see Metrics of basic GA instances.
In the Granularity drop-down list, select Acceleration Region or Accelerated IP.
If you select Accelerated IP, you can select the accelerated IP address whose metrics you want to view. You can select up to three accelerated IP addresses at a time.
In the Time drop-down list, select a time range.
By default, the system displays the monitoring data collected within the previous hour. You can select other time ranges from the Time drop-down list. The supported time ranges are 3 hours, 6 hours, and 12 hours. You can also specify a custom time range.
If you turn on Auto Refresh, the monitoring chart is automatically refreshed every minute.
Create a threshold-triggered alert rule
To monitor the usage and status of GA instances, you can create threshold-triggered alert rules. This way, you can make sure that GA instances run as expected.
If a GA instance is deleted, the threshold-triggered alert rules that are configured in the CloudMonitor console for the GA instance are also deleted.
Log on to the CloudMonitor console.
In the left-side navigation pane, choose .
On the Alert Rules page, click Create Alert Rule.
In the Create Alert Rule panel, specify the following parameters to create an alert rule and click Confirm.
The following table describes the parameters that are related to this topic. For more information about other parameters, see Create an alert rule.
