Integrate Splunk Data in the Pentaho Report Designer

The CData JDBC driver for Splunk data enables access to live data from dashboards and reports. This article shows how to connect to Splunk data as a JDBC data source and publish reports based on Splunk data in Pentaho.

Connect and Create a Report

1. Copy the JAR file of the driver, located in the lib subfolder of the installation directory, to the \Report-Designer\lib\jdbc\ folder in the Pentaho directory.
2. Run the report-designer.bat file in the \Report-Designer\ folder to open the Report-Designer UI.

3. Create a new data source with the driver by clicking Data -> Add Data Source -> Advanced -> JDBC (Custom) and then creating a new Splunk connection. In the resulting dialog, configure the connection properties as shown below.

   • Custom Connection URL property: Enter the JDBC URL. This starts with jdbc:splunk: and is followed by a semicolon-separated list of connection properties.

     To authenticate requests, set the , , and 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.

     When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

     Below is a typical JDBC URL:

     jdbc:splunk:user=MyUserName;password=MyPassword;URL=MyURL;InitiateOAuth=GETANDREFRESH;

   • Custom Driver Class Name: Enter cdata.jdbc.splunk.SplunkDriver.
   • User Name: The username to authenticate with.
   • Password: The password to authenticate with.
   👁 Required connection properties defined in the JDBC URL. (Salesforce is shown.)
   

Add Splunk Data to a Report

You are now ready to create a report with Splunk data.

1. Add the Splunk source to your report: Click Data -> Add Data Source -> JDBC and select the data source.

2. Configure the query. This article uses the one below:

   SELECT Name, Owner FROM DataModels

   👁 The query to retrieve data, specified in the JDBC data source configuration wizard. (Salesforce is shown.)
   
3. Drag a chart onto your report and double-click it to edit the chart. Run the report to display the chart. You can use the results of this query to create a simple chart for the DataModels table.
4. Finally, run the report to see the chart.
