Huawei Cloud GaussDB-Cassandra¶

The displayed Metrics for Huawei Cloud GaussDB-Cassandra include read/write throughput, latency, data consistency, and scalability. These Metrics reflect the performance and reliability of GaussDB-Cassandra when handling large-scale distributed data storage and access.

Configuration¶

Install Func¶

It is recommended to enable TrueWatch integration - extension - DataFlux Func (Automata): all prerequisites are automatically installed. Please continue with the script installation.

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

Installation Script¶

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

To synchronize monitoring data from Huawei Cloud DIS, we install the corresponding collection script: TrueWatch Integration (Huawei Cloud-GaussDB-Cassandra Collection)

After clicking [Install], input the corresponding parameters: Huawei Cloud AK, Huawei Cloud account name.

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

After the script is installed, find the script [TrueWatch Integration (Huawei Cloud-GaussDB-Cassandra Collection)]in the "Development" section of Func, expand and modify this script. Find collector_configs and monitor_configs respectively, edit the content of 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 immediately execute it once without waiting for the scheduled time. After a short wait, you can view the execution task records and corresponding logs.

We default collect some configurations, for details see the Metrics section Customize Cloud Object Metrics

Verification¶

1. In [Management / Automatic Trigger Configuration], confirm whether the corresponding task has an automatic trigger configuration, and you can also check the corresponding task records and logs for any abnormalities.
2. On the TrueWatch platform, under [Infrastructure / Custom], check if there is any asset information.
3. On the TrueWatch platform, under [Metrics], check if there is any corresponding monitoring data.

Metrics¶

After configuring Huawei Cloud - Cloud Monitoring, the default Measurement set is as follows. You can collect more Metrics through configuration Huawei Cloud Cloud Monitoring Metric Details

Objects¶

The collected Huawei Cloud GaussDB-Cassandra object data structure can be viewed in the "Infrastructure - Custom" section.

    "time_zone": "",
    "message": "{Instance JSON data}"
  }
}

Note: The fields in tags and fields may change with subsequent updates.

Tip 1: The value of tags.name is the Instance ID, which serves as a unique identifier.

Tip 2: The following fields are serialized JSON strings:

• fields.message
• fields.backup_strategy
• fields.datastore
• fields.groups
• fields.actions
