This section describes how to edit the DSN configuration and then authenticate and connect to Splunk APIs.

DSN Configuration

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the installation process creates a both a user DSN and a system DSN, as described in Installing the Connector.

Note: The connector stores connection information in the Windows registry. To ensure that the connector can write to the registry, either run Power BI as an administrator or use a User DSN for your connection instead of a System DSN.

User DSN

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
3. Select the system data source and click Configure.
4. Edit the information on the Connection tab and click OK.

System DSN

Configure the system DSN the same way as the user DSN, except you will need to switch to the System DSN tab before performing Step 3.

Connecting to Splunk APIs

You must specify the URL to a valid Splunk server. By default the connector makes requests on port 8089.

By default, the connector attempts to negotiate TLS/SSL with the server. For more information on TLS/SSL configuration, see SSL Configuration.

Authenticating to Splunk

There are two ways to authenticate to Splunk data: logging in with Splunk credentials, or using a Splunk authentication token.

Splunk Credentials

To authenticate with Splunk credentials, set User and Password to your login credentials.

Splunk Token

When you access Splunk via an authentication token, you can access the Splunk platform using Representational State Transfer (REST) calls. On Splunk Enterprise, you can also use the CLI. Both of these methods enable you to access the instance and make requests without having to authenticate via credentials.

Note: Unless you are accessing a search head cluster (where you can use the same token to access all available head clusters), you must have a separate token for each instance being accessed.

To authenticate with a Splunk token:

1. In the Splunk UI, navigate to Users and Authentication > Tokens to access your assigned authentication token. If you do not have one, request one from the administrator of the instance you want to access.
2. Set the AuthScheme to AccessToken; and the AccessToken property to your Splunk token.
