Create AlloyDB-Connected Dashboards in Grafana



Connect to AlloyDB Data via CData Connect Cloud in Grafana and create custom business dashboards with real-time access to AlloyDB data.

Grafana is an open-source platform that allows users to analyze, monitor, and visualize telemetry from various data sources. When combined with CData Connect Cloud, you gain immediate access to AlloyDB data for business dashboards. This article outlines the process of connecting to AlloyDB using Connect Cloud and creating a basic dashboard from AlloyDB data within Grafana.

CData Connect Cloud offers a pure SQL Server, cloud-to-cloud interface for AlloyDB, enabling the creation of dashboards directly from live AlloyDB data within Grafana, all without the need for data replication to a native database. As you build visualizations, Grafana generates SQL queries to gather data. With its inherent optimized data processing capabilities, CData Connect Cloud efficiently channels all supported SQL operations, including filters and JOINs, directly to AlloyDB. This leverages server-side processing to swiftly deliver the requested AlloyDB data.

Configure AlloyDB Connectivity for Grafana

Connectivity to AlloyDB from Grafana is made possible through CData Connect Cloud. To work with AlloyDB data from Grafana, we start by creating and configuring a AlloyDB connection.

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "AlloyDB" from the Add Connection panel
  3. Enter the necessary authentication properties to connect to AlloyDB.

    The following connection properties are usually required in order to connect to AlloyDB.

    • Server: The host name or IP of the server hosting the AlloyDB database.
    • User: The user which will be used to authenticate with the AlloyDB server.
    • Password: The password which will be used to authenticate with the AlloyDB server.

    You can also optionally set the following:

    • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
    • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

    Authenticating with Standard Authentication

    Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

    No further action is required to leverage Standard Authentication to connect.

    Authenticating with pg_hba.conf Auth Schemes

    There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

    Find instructions about authentication setup on the AlloyDB Server here.

    Authenticating with MD5 Authentication

    This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

    Authenticating with SASL Authentication

    This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

    Authenticating with Kerberos

    The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos.

  4. Click Create & Test
  5. Navigate to the Permissions tab in the Add AlloyDB Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to AlloyDB data from Grafana.

Visualize Live AlloyDB Data in Grafana

To establish a connection from Grafana to the CData Connect Cloud Virtual SQL Server API, follow these steps.

  1. If you have not already done so, download and install Grafana for your operating system from the Grafana Website. Once installed, access Grafana at http://localhost:3000/.
  2. Log in to Grafana with your username and password for Grafana. If this is your first time logging in, the username is admin and the password is admin.
  3. On the navigation menu, click Connections > Add new connection. On this page, you can search for Microsoft SQL Server and select it as your data source.
  4. Select Microsoft SQL Server and click Add new data source.
  5. Enter a name for the new data source and then enter the following connection settings:
    • Host: tds.cdata.com:14333
    • Database: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, AlloyDB1).
    • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
    • Password: enter the PAT you previously generated.
  6. Click Save & Test. A Database Connect OK message appears when you have a successful connection established.

Create a Dashboard

Once you create the data source for AlloyDB, you can start building dashboards on AlloyDB data. Start in the navigation menu and click Dashboards

  1. On the Dashboards page, click + Create dashboard, then click + Add visualization.
  2. This opens the Select data source window where you can select your created connection.
  3. After selecting your connection, you can choose the tables and columns that you want to query for your visualization. Then press Run Query to run the generated query.
  4. After running your query, the resulting data is populated above the query editor. Here you can select the visualization that you want to use to present your data on the dashboard panel.
  5. When you have finished editing your panel, you can click Save dashboard to save the changes made to your Dashboard.
