Configuring and using multiple data sources in OpenSearch Dashboards

You can ingest, process, and analyze data from multiple data sources in OpenSearch Dashboards. You configure the data sources under Dashboards Management > Data sources. This interface is shown in the following image.

Getting started

The following tutorial guides you through configuring and using multiple data sources in OpenSearch Dashboards.

The following features are not supported when using multiple data sources: timeline visualization types and the gantt-chart plugin.

Step 1: Modify the YAML file settings

To use multiple data sources, you must enable the data_source.enabled setting. It is disabled by default. To enable multiple data sources:

1. Open your local copy of the OpenSearch Dashboards configuration file, opensearch_dashboards.yml. If you don’t have a copy, opensearch_dashboards.yml is available on GitHub.
2. Set data_source.enabled: to true and save the YAML file.
3. Restart the OpenSearch Dashboards container.
4. Verify that the configuration settings were configured properly by connecting to OpenSearch Dashboards and viewing the Dashboards Management navigation menu. Data sources appears in the sidebar. You’ll see a view similar to the following image.

Step 2: Create a new data source connection

A data source connection specifies the parameters needed to connect to a data source. These parameters form a connection string for the data source.

To create a new data source connection:

1. From the OpenSearch Dashboards main menu, select Dashboards Management > Data sources > Create data source connection.

2. Add the required information to each field to configure the Connection Details and Authentication Method.

   • Under Connection Details, enter a title and endpoint URL. For this tutorial, use the URL https://localhost:9200/. Entering a description is optional.

   • Under Authentication Method, select an authentication method from the dropdown list. Once an authentication method is selected, the applicable fields for that method appear. You can then enter the required details. The authentication method options are:
     • No authentication: No authentication is used to connect to the data source.
     • Username & Password: A basic username and password are used to connect to the data source.
     • AWS SigV4: An AWS Signature Version 4 authenticating request is used to connect to the data source. AWS Signature Version 4 requires an access key and a secret key.
       • For AWS Signature Version 4 authentication, first specify the Region. Next, select the OpenSearch service from the Service Name list. The options are Amazon OpenSearch Service and Amazon OpenSearch Serverless. Last, enter the Access Key and Secret Key for authorization.

     For information about available AWS Regions for AWS accounts, see Available Regions. For more information about AWS Signature Version 4 authentication requests, see Authenticating Requests (AWS Signature Version 4).

   • After you have entered the appropriate details in all of the required fields, the Test connection and Create data source buttons become active. You can select Test connection to confirm that the connection is valid.

3. Select Create data source to save your settings. The connection is created, and the new data source appears in the list on the Data Sources main page. The first data source you create is marked as your default.

4. Edit or update a data source connection.

   • On the Data Sources main page, select the connection you want to modify. The Connection Details window opens.

   • To mark the selected data source as the default, select the Set as default option.

   • To make changes to Connection Details, edit one or both of the Title and Description fields and select Save changes in the lower-right corner of the screen. You can also cancel changes here. To change the Authentication Method, choose a different authentication method, enter your credentials (if applicable), and then select Save changes in the lower-right corner of the screen. The changes are saved.

     • When Username & Password is the selected authentication method, you can update the password by choosing Update stored password next to the Password field. In the pop-up window, enter a new password in the first field and then enter it again in the second field to confirm. Select Update stored password in the pop-up window. The new password is saved. Select Test connection to confirm that the connection is valid.
     • When AWS SigV4 is the selected authentication method, you can update the credentials by selecting Update stored AWS credential. In the pop-up window, enter a new access key in the first field and a new secret key in the second field. Select Update stored AWS credential in the pop-up window. The new credentials are saved. Select Test connection in the upper-right corner of the screen to confirm that the connection is valid.

5. Delete the data source connection by selecting the check box to the left of the title and then choosing Delete 1 connection. Selecting multiple check boxes for multiple connections is supported. Alternatively, select the icon.

A data source connection interface is shown in the following image.

Selecting multiple data sources through the Dev Tools console

Alternatively, you can select multiple data sources through the Dev Tools console. This option allows you to work with a broader range of data and gaining a deeper understanding of your code and applications.

Watch the following 10-second video to see it in action.

To select a data source through the Dev Tools console, follow these steps:

1. Locate your copy of opensearch_dashboards.yml and open it in the editor of your choice.
2. Set data_source.enabled to true.
3. Connect to OpenSearch Dashboards and select Dev Tools in the menu.

4. Enter the following query in the editor pane of the Console and then select the play button:

    GET /_cat/indices
   

5. From the Data source dropdown menu, select a data source and then query the source.
6. Repeat the preceding steps for each data source you want to select.

Uploading saved objects to a dashboard from connected data sources

To upload saved objects from connected data sources to a dashboard with multiple data sources, export them as an NDJSON file from the data source’s Saved object management page. Then upload the file to the dashboard’s Saved object management page. This method can simplify the transfer of saved objects between dashboards. The following 20-second video shows this feature in action.

Importing saved objects from a connected data source

Follow these steps to import saved objects from a connected data source:

1. Locate your opensearch_dashboards.yml file and open it in your preferred text editor.
2. Set data_source.enabled to true.
3. Connect to OpenSearch Dashboards and go to Dashboards Management > Saved objects.
4. Select Import > Select file and upload the file acquired from the connected data source.
5. Choose the appropriate Data source from the dropdown menu, set your Conflict management option, and then select the Import button.

Showing or hiding authentication methods

Introduced 2.13

A feature flag in your opensearch_dashboards.yml file allows you to show or hide authentication methods within the data_source plugin. The following setting hides the authentication method for AWSSigV4.

# Set enabled to false to hide the authentication method from multiple data source in OpenSearch Dashboards.
# If this setting is commented out, then all three options will be available in OpenSearch Dashboards.
# The default value will be considered as true.
data_source.authTypes:
   NoAuthentication:
     enabled: true
   UsernamePassword:
