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 Guance 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: 「Guance Integration (Huawei Cloud-GaussDB-Cassandra Collection)」(ID: guance_huaweicloud_gaussdb_cassandra)

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 「Guance 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 Guance platform, under 「Infrastructure / Custom」, check if there is any asset information.
3. On the Guance 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
