Alibaba Cloud NAT¶

Alibaba Cloud NAT Metrics display, including concurrent connections, new connections, VPC traffic, VPC packets, etc.

Configuration¶

Install Func¶

It is recommended to enable Guance Integration - Extension - DataFlux Func (Automata)

If you deploy Func yourself, refer to Self-deployed Func

Enable Script¶

Note: Please prepare an Alibaba Cloud AK that meets the requirements in advance (for simplicity, you can directly grant global read-only permission ReadOnlyAccess).

Script for Enabling Managed Version¶

Log in to Guance Console
Click on the 【Manage】 menu and select 【Cloud Account Management】
Click 【Add Cloud Account】, choose 【Alibaba Cloud】, and fill in the required information on the interface; if cloud account information has been configured before, skip this step
Click 【Test】, after a successful test click 【Save】; if the test fails, check whether the related configuration information is correct and retest
In the 【Cloud Account Management】 list, you can see the added cloud account, click on the corresponding cloud account to enter the details page
Click the 【Integration】 button on the cloud account details page, under the Not Installed list, find Alibaba Cloud NAT, click the 【Install】 button, and install via the pop-up installation interface.

Manual Enablement Script¶

Log in to the Func Console, click 【Script Market】, enter the official script market, and search: guance_aliyun_nat
After clicking 【Install】, input the corresponding parameters: Alibaba Cloud AK ID, AK Secret, and account name.
Click 【Deploy Startup Script】, the system will automatically create a Startup script set and automatically configure the corresponding startup script.
After enabling, you can see the corresponding automatic trigger configuration in 「Management / Automatic Trigger Configuration」. Click 【Execute】 to immediately execute once without waiting for the scheduled time. Wait a moment, and you can view the execution task records and corresponding logs.

We default collect some configurations, details are shown in the metrics section.

Configure Custom Cloud Object Metrics

Verification¶

In 「Management / Automatic Trigger Configuration」 confirm that the corresponding task exists with the appropriate automatic trigger configuration, and you can check the task records and logs to ensure there are no anomalies.
In Guance, 「Infrastructure / Custom」 check if asset information exists.
In Guance, 「Metrics」 check if there is corresponding monitoring data.

Metrics¶

After configuring Alibaba Cloud - Cloud Monitoring, the default metric set is as follows. You can collect more metrics through configuration. Alibaba Cloud Cloud Monitoring Metric Details
