HUAWEI CLOUD DDM¶

The HUAWEI CLOUD DDM monitoring view displays metrics including message throughput, latency, concurrent connections, and reliability, which reflect the performance and reliability assurance of DDM in handling large-scale message delivery and real-time data flow

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 HUAWEI CLOUD AK that meets the requirements in advance（For simplicity's sake,You can directly grant the global read-only permissionReadOnlyAccess）

To synchronize the monitoring data DDM, install the corresponding data collection script: "Guance Integration (HUAWEI CLOUD SYS.DDMS Collect)" (ID: startup__guance_huaweicloud_ddm).

Click [Install] and enter the corresponding parameters: HUAWEI CLOUD AK, HUAWEI CLOUD account name.

Click [Deploy Startup Scripts], the system will automatically create the Startup script set and automatically configure the corresponding startup scripts.

You can see the corresponding auto-trigger configuration in "Management / Auto-trigger Configuration" after you turn it on. Click "Execute" to execute the task immediately without waiting for the regular time. Wait for a while, you can check the record and log of the executed task.

Verify¶

Check whether the automatic triggering configuration exists for the corresponding task in "Management / Crontab Config". Additionally, you can review task records and logs to identify any exceptions.
On the Guance platform, go to "Infrastructure / Custom" to verify the presence of asset information.
Press "Metrics" on the Guance platform to confirm the availability of monitoring data.

Metrics¶

After configuring HUAWEI CLOUD Cloud Monitoring, the default metric set is as follows, and more metrics can be collected through configuration

After configure HUAWEI CLOUD - cloud monitoring, the default metric set is as follows. You can collect more metrics by configuring them HUAWEI CLOUD Monitor Metrics Details
