Aliyun PolarDB distributed2.0¶

Aliyun PolarDB distributed2.0 displays metrics of the computing layer and storage nodes, including CPU usage, connection usage, disk usage, disk usage, memory usage, and network bandwidth.

Config¶

Install Func¶

Recommend opening [ Integrations - Extension - DataFlux Func (Automata) ]: All preconditions are installed automatically, Please continue with the script installation

If you deploy Func yourself,Refer to Self-Deployment of Func

Installation script¶

Tip: Please prepare AWS AK that meets the requirements in advance (For simplicity's sake, you can directly grant the global read-only permission for CloudWatch CloudWatchReadOnlyAccess)

To synchronize the monitoring data of PolarDB distributed 2.0 cloud resources, we install the corresponding collection [ Guance Integration（Aliyun-PolarDB-X 1.0Collect）] (ID: guance_aliyun_polardbx_2)

Click [Install] and enter the corresponding parameters: Aliyun AK ID, Aliyun AK SECRET and Account Name.

Tap [Deploy startup Script],The system automatically creates Startup script sets,And automatically configure the corresponding startup script.

Then, in the collection script, add the collector_Configs and cloudwatch_Change the regions in configs to the actual regions

After this function is enabled, you can view the automatic triggering configuration in [Management / Crontab Config]. Click[Run],you can immediately execute once, without waiting for a regular time. After a while, you can view task execution records and corresponding logs.

We collected some configurations by default, as described in the Metrics column Configure custom cloud object metrics

Verify¶

1. In「Management / Crontab Config」check whether the automatic triggering configuration exists for the corresponding task,In addition, you can view task records and logs to check whether exceptions exist
2. On the Guance platform, click 「Infrastructure / Custom」 to check whether asset information exists
3. On the Guance platform, press 「Metrics」 to check whether monitoring data exists

Metric¶

After Configure Aliyun PolarDB distributed 2.0 monitoring, the default metric set is as follows. You can collect more metrics by configuring them

Object¶

The collected Aliyun PolarDB distributed 2.0 object data structure can be seen from the [ Infrastructure - Custom] object data.
