Splunk JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Splunk data including Datamodels, Datasets, SearchJobs, and more!



Create a simple Mule Application that uses HTTP and SQL with the CData JDBC Driver for Splunk to create a JSON endpoint for Splunk data.

The CData JDBC Driver for Splunk connects Splunk data to Mule applications enabling read , write, update, and delete functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze Splunk data.

This article demonstrates how to use the CData JDBC Driver for Splunk inside of a Mule project to create a Web interface for Splunk data. The application created allows you to request Splunk data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver to create a Web interface for the 200+ available data sources.

  1. Create a new Mule Project in Anypoint Studio.
  2. Add an HTTP Connector to the Message Flow.
  3. Configure the address for the HTTP Connector.
  4. Add a Database Select Connector to the same flow, after the HTTP Connector.
  5. Create a new Connection (or edit an existing one) and configure the properties.
    • Set Connection to "Generic Connection"
    • Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.splunk.jar).
    • Set the URL to the connection string for Splunk

      To authenticate requests, set the User, Password, and URL properties to valid Splunk credentials. The port on which the requests are made to Splunk is port 8089.

      The data provider uses plain-text authentication by default, since the data provider attempts to negotiate TLS/SSL with the server.

      If you need to manually configure TLS/SSL, see Getting Started -> Advanced Settings in the data provider help documentation.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the Splunk JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.splunk.jar

      Fill in the connection properties and copy the connection string to the clipboard.

    • Set the Driver class name to cdata.jdbc.splunk.SplunkDriver.
    • Click Test Connection.
  6. Set the SQL Query Text to a SQL query to request Splunk data. For example: SELECT Name, Owner FROM DataModels
  7. Add a Transform Message Component to the flow.
  8. Set the Output script to the following to convert the payload to JSON:
    %dw 2.0
    output application/json
    ---
    payload
            
  9. To view your Splunk data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The Splunk data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with Splunk data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the JDBC Driver for Splunk and see the CData difference in your Mule Applications today.
