Huawei Cloud DDM¶

'The monitoring view of Huawei Cloud DDM displays metrics including message throughput, latency, concurrent connections, and reliability. These metrics reflect the performance and reliability guarantees of DDMS when handling large-scale message delivery and real-time data streams.'

Configuration¶

Install Func¶

It is recommended to activate TrueWatch Integration - Extensions - DataFlux Func (Automata): All prerequisites are automatically installed. Please proceed with the script installation.

For self-deployment of Func, refer to Self-deploy Func

Install Script¶

Note: Please prepare the Huawei Cloud AK with the required permissions in advance (for simplicity, you can grant the global read-only permission ReadOnlyAccess)

Log in to the Func console, click 【Script Market】, and enter the TrueWatch Script Market. Search for ID: integration_huaweicloud_ddm
Click 【Install】, then enter the corresponding parameters: Huawei Cloud AK, SK, and account name
Click 【Deploy Startup Script】, the system will automatically create the Startup script set and configure the corresponding startup scripts
After enabling, you can see the corresponding automatic trigger configuration in 「Manage / Automatic Trigger Configuration」. Click 【Execute】 to immediately execute it once without waiting for the scheduled time. After a short while, you can check the execution task records and corresponding logs

Verification¶

In 「Manage / Automatic Trigger Configuration」, confirm whether the corresponding task has the automatic trigger configuration. At the same time, check the task records and logs to see if there are any exceptions
In TrueWatch, check if asset information exists in 「Infrastructure / Custom」
In TrueWatch, check if there is corresponding monitoring data in 「Metrics」

Metrics¶

After configuring Huawei Cloud Cloud Monitoring, the default measurement sets are as follows. More metrics can be collected through configuration.

Metric Id	Metric Name	Dimensions	Statistics	Unit
ddm_active_connections_average	Average of Active Connections	userId,instanceId	Average,Maximum	Count
ddm_bytes_in_average	Average Bytes Received per Second	userId,instanceId	Average,Maximum	Bytes/sec
ddm_bytes_out_average	Average Bytes Sent per Second	userId,instanceId	Average,Maximum	Bytes/sec
ddm_cpu_util_average	Average CPU Utilization	userId,instanceId	Average,Maximum	Percentage
ddm_qps_average	Average Queries per Second	userId,instanceId	Average,Maximum	Queries/sec
ddm_node_status_alarm_code_average	Average Alarm Code of Node Status	userId,instanceId	Average,Maximum	Count
ddm_write_count_average	Average Writes per Second	userId,instanceId	Average,Maximum	Writes/sec
ddm_rt_avg_average	Average Response Time	userId,instanceId	Average,Maximum	ms

Object¶

The collected data structure of Huawei Cloud SYS.DDMS objects can be seen in 「Infrastructure - Custom」.
