HUAWEI CLOUD GaussDB-Cassandra

Use the「Guance Synchronization」series script package in the script market to synchronize data from cloud monitoring cloud assets to the observation cloud.

ConfiG

Install Func

Recommend opening 「Integrations - Extension - DataFlux Func (Automate)」: 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 of HUAWEI CLOUD GaussDB-Cassandra cloud resources, we install the corresponding collection script：「Guance Integration（HUAWEI CLOUD GaussDB-Cassandra Collect）」(ID：guance_huaweicloud_gaussdb_cassandra)

Click 【Install】 and enter the corresponding parameters: HUAWEI CLOUD AK, HUAWEI CLOUD account name.

tap【Deploy startup Script】, The system automatically creates Startup script sets, And automatically configure the corresponding startup script.

After the script is installed, Find the script in「Development」in Func「Guance Integration（HUAWEI CLOUD-GaussDB-CassandraCollect）」, Expand to modify this script, find collector_configsandmonitor_configsEdit the content inregion_projects, Change the locale and Project ID to the actual locale and Project ID, Click Save Publish again.

In addition, the corresponding automatic trigger configuration is displayed in「Management / Crontab Config」. tap【Run】, It can be executed immediately once, without waiting for a periodic time. After a while, you can view task execution records and corresponding logs.

We collected some configurations by default, as described in the Metrics column Configure custom cloud object metrics

Verify

  1. In「Management / Crontab Config」check whether the automatic triggering configuration exists for the corresponding task,In addition, you can view task records and logs to check whether exceptions exist
  2. On the observation cloud platform, click 「Infrastructure / Custom」 to check whether asset information exists
  3. On the observation cloud platform, press 「Metrics」 to check whether monitoring data exists

Metric

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
