Huawei Cloud DDS
Collect Huawei Cloud DDS Metrics
Configuration¶
Install Func¶
It is recommended to activate TrueWatch Integration - Extensions - DataFlux Func (Automata): All prerequisites are automatically installed, please proceed with script installation.
For self-deployed Func, refer to Self-deployed Func
Install Script¶
Note: Prepare Huawei Cloud AK in advance (for simplicity, you can grant global read-only permission
ReadOnlyAccess)
To synchronize Huawei Cloud DDS monitoring data, we install the corresponding collection scripts:
- integration_huaweicloud_dds: Collect DDS monitoring metrics
- integration_huaweicloud_dds_slowlog: Collect DDS slow log data
After clicking [Install], enter the corresponding parameters: Huawei Cloud AK, Huawei Cloud account name.
Click [Deploy Startup Script], the system will automatically create a Startup script set and configure the corresponding startup script.
After the script installation is complete, find the script "TrueWatch Integration (Huawei Cloud-DDS Collection)" / "TrueWatch Integration (Huawei Cloud-DDS Slow Query Log Collection)" in Func under "Development", expand and modify the script, find collector_configs and monitor_configs respectively to edit the content in region_projects, change the region and Project ID to the actual region and Project ID, then click Save and Publish.
In addition, you can see the corresponding automatic trigger configuration in "Management / Automatic Trigger Configuration". Click [Execute] to execute it immediately without waiting for the scheduled time. After a while, you can check the execution task records and corresponding logs.
Verification¶
- In "Management / Automatic Trigger Configuration", confirm whether the corresponding task has the corresponding automatic trigger configuration, and check the corresponding task records and logs for any exceptions
- In TrueWatch, check if asset information exists in "Infrastructure - Resource Catalog"
- In TrueWatch, check if there is corresponding monitoring data in "Metrics"
- In TrueWatch, check if there is corresponding slow log data in "Logs"
