Precautions​

  • To ensure the service can connect smoothly, please first select on the page, and then add the NineData service IP address located in the position of the figure below to the whitelist of your server. How to add a whitelist in an IDC self-built database, please refer to Appendix II. How to add a whitelist in cloud vendor servers or databases, please refer to the official documents of each cloud vendor.

  • Please ensure that you still have free data source quotas, otherwise, you will not be able to enter data sources. You can quickly check the remaining quota in the upper right corner of the NineData console page. check_quota

Adding Cloud Vendor Data Sources​

  1. Log in to the NineData Console.

  2. On the left navigation pane, click > .

  3. Click  tab, and click  on the page. In the popup window for selecting the data source type, choose （Cloud Vendor Name） > (the type of data source to be added), and configure the parameters based on the table below on the page.
    tip

    If you make a mistake during the operation, you can click the arrow_down icon at the top of the page to make a new selection.

Supported instance types:

  • DataHub

Parameter
Description
Enter the name of the data source. To facilitate subsequent search and management, please use meaningful names as much as possible.
Choose the access method of the data source.
  • : Connect through the cloud vendor's private network connection address, suitable for scenarios with high requirements for transmission rate. You need to first connect this private network address to NineData. The connection method is described in Add Private Network Address, and then select the connected below.
  • : Connect to the data source through the public network address, and enter the public connection address of the instance in .
  • (only supports self-built databases): A secure and fast intranet access method provided by NineData. You need to first connect the host where the data source is located. The connection method is described in Add Gateway. Then select the connected and below, and can be written as localhost or intranet IP.
  • SSH Tunnel: Connect to the data source through an SSH tunnel. You also need to provide , , and other SSH-related information. For detailed configuration steps, please refer to:
Choose the access method of Alibaba Cloud instances, which supports access in the form of or .
  • : Access through the instance ID of ECS or cloud database. To choose this option, you also need to select , , and and other parameters. needs to be configured in advance. The configuration method is described in Configure Cloud Vendor Access Credentials.
  • : Access through the connection address of the instance. Depending on the , is different. For details, please refer to the description of above.
Required when the data source is MongoDB, specifying the authentication database for the current user.
The username of the data source.
The password of the data source.
Only required when accessing the data source through the connection address. Choose the region closest to the location of your data source to effectively reduce network latency.
Select based on the actual business purpose of the data source, as an environmental identifier for the data source. The default provides and environments, and also supports you to create a custom environment.
Note: Under the organization mode, the database environment can also be applied to permission policy management. For example, the default role only supports access to data sources in the environment and cannot access data sources in other environments. For more information, please refer to Manage Roles.
Whether to use SSL encryption to access the data source. If the data source enforces SSL encryption connection, this switch must be turned on, otherwise, the connection fails.
Click the switch on the right to turn on or off encrypted transmission. Some data source types can click the > on the left side of to expand detailed configuration.
Note: Different types of data sources support different options, please refer to the console.
  1. After completing all the configurations, you can click on the right side of and select to test if the data source can be accessed successfully. If you see indicating a successful connection test, you can then proceed to click on to finalize the addition of the data source. If the connection test does not succeed, please review your connection settings and keep testing until the connection is successfully established.

Appendix 1: Creating an Environment​

To meet the needs of different enterprises, in addition to providing default and environments, NineData also supports manually creating custom environments.

  1. Log in to the NineData Console.

  2. In the left navigation bar, click >.

  3. Click on the tab. This shows all the environments currently under the user (personal mode) or organization (organization mode). Here you can or custom created environments.

  4. Click on in the upper right corner of the page.

  5. Complete the configuration according to the following table and click .

    ParameterDescription
    Enter the name of the environment, which can contain 1 to 16 characters. This name serves as the identifier of the environment and needs to have some distinguishing characteristics. Please try to use meaningful names.
    Choose the color of the environment label displayed in the console.

Appendix 2: Add NineData's IP address to the database allowlist (self-built database environment)​

When adding a data source located at , the IP address of the NineData service must be added to the database allowlist to allow NineData to provide services.

This section takes MySQL 8.0 as an example to introduce how to add IP allowlist.

  • New account: Log in to the database using the Root account, and create an account for NineData to access and authorize the corresponding permissions with the following command.

    CREATE USER '<account name>'@'<NineData IP address>' IDENTIFIED BY '<access password>';
    GRANT <privilege name> ON <database name>.* TO '<account name>'@'<NineData IP address>';

  • Existing account: Log in to the database using the Root account, and add NineData IP allowlist and grant corresponding permissions to the existing account with the following command.

GRANT <privilege name> ON <database name>.* TO '<account name>'@'<NineData IP address>' IDENTIFIED BY '<access password>';
tip

When adding a MySQL data source, you need to use the account and corresponding password that have added NineData's IP address as mentioned above.

Appendix 3: Add multi-active tag to data sources ​

If the data source serves for multi-node replication tasks (data replication between three or more data sources), in order to prevent circular replication, multi-active flags are required for all data sources participating in the replication, The multi-active tag of each data source must be globally unique.

  1. Log in to NineData Console.

  2. In the navigation pane on the left, click Datasource>Datasource.

  3. Click the target data source ID to open the Data Source Details page.

    1. In the data source details area (including data source name, ID, creator, creation time, etc.), click Show Details.

  4. Find Multi-Active Tag, click the edit icon on the right side of it.

  5. Enter the Multi-Active Tag, and click OK.

    tip
    • Multi-active tag can contain 1~64 characters.
    • The multi-active tag must be globally unique and cannot be duplicated with other multi-active tag.

Appendix 4: Create Tags​

Tags are used for custom grouping in the slow query analysis feature of the Database DevOps module. By configuring tags for specific data sources, you can flexibly group and display slow queries on the dashboard based on business logic, departments, or other requirements. This helps you more precisely identify and address performance bottlenecks.

  1. Log in to the NineData console.

  2. In the left navigation bar, click > .

  3. Click the tab and then click on the page.

  4. In the pop-up dialog, enter the and click .

    tip
    • The tag name must be globally unique.
    • After creating the tag, you need to bind it to the target data source in the slow query analysis module. For more information, see Slow Query Analysis.

Common problem​

IssuePossible CauseSolution
Error when adding a data source: http connections are not allowed from xxx.xxx.xxx.xxx:xxxxx.NineData service's IP address is not whitelisted on your server.Before adding a data source, make sure to add NineData's service address to your data source whitelist. For more information, please refer to the Precautions section in this article.
