Working with Splunk Data in LINQPad

Execute LINQ queries to Splunk data in LINQPad.

The CData ADO.NET Provider for Splunk enables you to use standard ADO.NET interfaces like LINQ and the Entity Framework to work with Splunk data. This article shows how to connect from LINQPad and execute LINQ queries.

Create the Data Model

After downloading and installing the provider and LINQPad, create a new class library project in Visual Studio.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

  1. Right-click your project and click Add -> New Item -> ADO.NET Entity Data Model. In the resulting dialog, select Code First from database. Click New Connection and specify the connection string options in the resulting wizard.

    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.

    Below is a typical connection string:

    user=MyUserName;password=MyPassword;URL=MyURL;
  2. Select the desired tables and views and click Finish to create the data model.

  3. Build the project. The generated files can be used to create the Splunk connection in LINQPad.

Connect to Splunk Data in LINQPad

After you have obtained the required connection properties and created the data model assembly, follow the steps below to start using the data model in LINQPad.

  1. Open LINQPad and click Add Connection.

  2. Select the "Use a typed data context from your own assembly" option.

  3. Select Entity Framework DbContext.

  4. Click Browse next to the Path to Custom Assembly box and browse to your project folder. Browse to the .dll or .exe under the bin folder.

  5. Select the name of the DbContext.
  6. If you saved your connection string in App.Config, specify the path to the App.config.

You can now query Splunk data through LINQPad. For examples of the supported LINQ queries, see the "LINQ and Entity Framework" chapter in the help documentation.
