Analyze Elasticsearch Data in Cognos Analytics



Use CData Connect Cloud to connect to Elasticsearch Data from Cognos Analytics and analyze live Elasticsearch data.

Cognos Analytics, powered by IBM Watson®, empowers users to cleanse and establish connections with their data while creating visualizations. When integrated with CData Connect Cloud, users gain immediate, real-time connectivity between cloud-based data sources and Cognos Analytics, facilitating data management, visualization, analytics, and more. This article provides step-by-step guidance on connecting to Elasticsearch via CData Connect Cloud and subsequently analyzing Elasticsearch data within Cognos Analytics.

NOTE: These instructions require Cognos Analytics 11.2.4 or higher

CData Connect Cloud offers a dedicated cloud-to-cloud interface for Elasticsearch, enabling users to perform real-time analysis on Elasticsearch data within Cognos without the need to replicate data to a natively supported database. Equipped with built-in optimized data processing capabilities, CData Connect Cloud efficiently directs all supported SQL operations, including filters and JOINs, directly to Elasticsearch. This harnesses server-side processing to promptly provide the requested Elasticsearch data.

Configure Elasticsearch Connectivity for Cognos Analytics

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

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

    Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.

    The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.

    Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.

  4. Click Create & Test
  5. Navigate to the Permissions tab in the Add Elasticsearch 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 Elasticsearch data from Cognos Analytics.

Connect to Elasticsearch from Cognos Analytics

The steps below outline connecting to CData Connect Cloud from Cognos Analytics to analyze live Elasticsearch data.

Download the CData Connect Cloud JDBC Driver

  1. Download and install the CData Connect Cloud JDBC Driver: https://www.cdata.com/cloud/clients/download.aspx#jdbc.
  2. Copy the JAR file (cdata.jdbc.connect.jar) from the installation directory (e.g., C:\Program Files\CData\JDBC Driver for CData Connect\lib) to the "drivers" folder in your Cognos Analytics installation directory.

Configure the Connection to CData Connect Cloud

  1. Open IBM Cognos and navigate to Manage > Data server connections.
  2. Click the icon to add a data server.
  3. Select CData Connect Cloud.
  4. Set JDBC URL to the appropriate connection string. For example: jdbc:connect://AuthScheme=Basic;
  5. Set Driver class name to "cdata.jdbc.connect.ConnectDriver"
  6. Create and store authenticate credentials by selecting an authentication method
    • Set Username to your CData Connect Cloud username (e.g., [email protected])
    • Set Password to the PAT you previously generated.
  7. Click Test connection to confirm that the connection succeeds.

At this point, you are ready to analyze and visualize Elasticsearch data in Cognos Analytics. For more information about using Cognos Analytics, please refer to the Cognos Analytics documentation.
