Alibaba Cloud ECS¶

The displayed metrics for Alibaba Cloud ECS include CPU utilization, memory utilization, network bandwidth, and disk IOPS. These metrics reflect the performance of ECS instances in terms of computing, memory, networking, and storage.

Configuration¶

Install Func¶

It is recommended to enable the TrueWatch integration - extension - managed Func: all prerequisites are automatically installed. Please proceed with script installation.

If you deploy Func on your own, refer to Self-hosted Func Deployment

Enable Script¶

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

Enable Managed Script¶

Log in to the TrueWatch console.
Click on the [Manage] menu and select [Cloud Account Management].
Click [Add Cloud Account], select [Alibaba Cloud], and fill in the required information on the interface. If the 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 configuration information is correct and retest.
In the [Cloud Account Management] list, you can see the added cloud accounts. Click on the corresponding cloud account to enter the details page.
Click the [Integration] button on the cloud account details page. In the Not Installed list, find Alibaba Cloud ECS, click the [Install] button, and follow the installation interface to complete the installation.

Manually Enable Script¶

Log in to the Func console, click [Script Market], enter the official script market, and search for _aliyun_ecs.
After clicking [Install], input the corresponding parameters: Alibaba Cloud AK ID, AK Secret, and account name.
Click [Deploy Start Script], and the system will automatically create a Startup script set and automatically configure the corresponding start script.
After enabling, you can see the corresponding automatic trigger configuration in [Management / Automatic Trigger Configuration]. Click [Execute] to run it immediately without waiting for the scheduled time. After a short wait, you can view the execution task records and corresponding logs.

We default to collecting some configurations; for more details, see the Metrics section.

Verification¶

In "Manage / Automatic Trigger Configuration", confirm whether the corresponding task has the corresponding automatic trigger configuration, and check the corresponding task records and logs to ensure there are no abnormalities.
In the TrueWatch platform, under "Infrastructure / Custom", check if there is asset information.
In the TrueWatch platform, under "Metrics", check if there are corresponding monitoring data.

Metrics¶

After configuring Alibaba Cloud - Cloud Monitor, the default metric sets are as follows. You can collect more metrics through configuration. Alibaba Cloud Cloud Monitor Metric Details

Note: You need to install the monitoring plugin in the Aliyun ECS console.
