To learn more about the join command, see How the join command works.ġ. Build Charts and Analyze Data – Begin your data analysis.The following are examples for using the SPL2 join command.Set Up Data Sources – Add more data to this data source or prepare your data before you analyze it.A cross-database join between Splunk tables causes all the connections in the Tableau data source to disappear except for the last Splunk connection. Note: Creating a cross-database join between Splunk tables is not supported. For more information about cross-database joins, see Join Your Data. You cannot drag the table from the left pane to the canvas as you normally would when creating a cross-database join. After adding a new connection to the Tableau data source, you must double-click the table in the left pane to add it to the canvas. However, you can create a cross-database join between Splunk data and data from different databases (or files) with one exception. For more information, Extract Your Data and Join Your Data. For more information, see Blend Your Data.Ĭreate an extract: Create an extract of each Splunk table and then join the extracts together using a cross-database join. Use data blending: Set up a data source for each Splunk table you need, then use data blending to combine the data. Then connect to this saved search from Tableau Desktop. Set up and connect to a saved search: Set up a saved search in Splunk that returns all the tables you need in a single search result. While you cannot create a join between Splunk tables, you can combine Splunk data from multiple tables by doing one of the following: Select the sheet tab to start your analysis. Under Saved Search, enter a saved search name in the text box or select a saved search from the list, and drag it to the box at the top of the data source page. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to. (Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau. On the data source page, do the following: If you still can't connect, yourĬomputer is having trouble locating the server. If Tableau can't make the connection, verify that your credentials are correct. For more information, see Run Initial SQL. (Optional) Select Initial SQL to specify a SQL command to run at the beginning of every connection, such as when you open the workbook, refresh an extract, sign in to Tableau Server, or publish to Tableau Server. If your server contains multiple databases, enter the name of a specific database on the server. You should use HTTPS to connect to Splunk data. Then do the following:Įnter the server URL. For a complete list of data connections, select More under To a Server. Start Tableau and under Connect, select Splunk. Make the connection and set up the data source If the driver is not installed on your computer, Tableau displays a message in the connection dialog box with a link to the Driver Download (Link opens in a new window) page where you can find driver links and installation instructions. You might already have the required driver installed on your computer. This connector requires a driver to talk to the database. Use this connector with Tableau Desktop on a Windows computer. (Optional) Initial SQL statement to run every time Tableau connects Server URL, including the name of the database, if there are multiple databases Before you beginīefore you begin, gather this connection information: Note: The Splunk ODBC connector is compatible with Splunk Enterprise 6. This article describes how to connect Tableau to Splunk data and set up a data source.
