Use CData JDBC drivers to import and use Splunk data in ColdFusion.
Adobe ColdFusion is a web and mobile application development platform. It uses its own scripting language, ColdFusion Markup Language (CFML), to create data-driven websites as well as generate remote services, such as REST.
When ColdFusion is paired with the CData JDBC Driver for Splunk, you can link your ColdFusion web and mobile applications to operational Splunk data. This allows for your applications to be more robust and complete. This article details how to use the JDBC driver to create a table populated with Splunk data from within a ColdFusion markup file.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Splunk data. When you issue complex SQL queries to Splunk, the driver pushes supported SQL operations, like filters and aggregations, directly to Splunk and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Splunk data using native data types.
Configuring the Connection to Splunk
You will need a JDBC connection string to establish a connection between Coldfusion and 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
Adding a Data Source and Creating a Table
After configuring the connection, follow the steps below to add the CData JDBC Driver to ColdFusion's lib directory, add a new data source, test the connection, create a ColdFusion markup file, and, finally, make a real-time connection with Splunk data and display it in a table written in the ColdFusion Markup Language, or CFML:
-
Copy the JDBC Driver for Splunk and lic file from "C:\Program Files\CData[product_name]\lib" to
"C:\ColdFusion2021\cfusion\wwwroot\WEB-INF\lib".
cdata.jdbc.splunk.jar cdata.jdbc.splunk.lic
Note: If you do not copy the .lic file with the jar, you will see a licensing error that indicates you do not have a valid license installed. This is true for both the trial and full versions.
- From the ColdFusion administrator interface, choose Data & Services.
- Here, we can "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our JDBC driver, choose "other", then click the "Add" button.
-
Next, populate the driver properties.
- JDBC URL will need to be in the format: jdbc:splunk:|connectionString|.
- A typical connection string looks like this:
jdbc:splunk:user=MyUserName;password=MyPassword;URL=MyURL;InitiateOAuth=GETANDREFRESH
- The Driver Class is: cdata.jdbc.splunk.SplunkDriver
- The Driver Name is arbitrary and simply used to recognize the data source in the ColdFusion administration console.
- Now, test the connection by clicking the check mark to the left of the CDataSplunkJDBC data source you just created. When the data source reports an "OK" status, it is ready for use.
-
Next, create a new ColdFusion Markup file (.cfm) and place it in the wwwroot directory ("C:\ColdFusion2021\cfusion\wwwroot")
for ColdFusion.
The following code queries the data source:
<cfquery name="SplunkQuery" dataSource="CDataSplunkJDBC"> SELECT * FROM DataModels </cfquery>
And a CFTable can be used to quickly output the table in HTML:<cftable query = "SplunkQuery" border = "1" colHeaders colSpacing = "2" headerLines = "2" HTMLTable maxRows = "500" startRow = "1"> <cfcol header="<b>Name</b>" align="Left" width=2 text="Name"/> <cfcol header="<b>Owner</b>" align="Left" width=15 text="Owner"/> ... </cftable>
Full code, including the HTML portion is available below:<html> <head><title>CData Software | Splunk DataModels Table Demo </title></head> <body> <cfoutput>#ucase("Splunk DataModels Table Demo")#</cfoutput> <cfquery name="SplunkQuery" dataSource="CDataSplunkJDBC"> SELECT * FROM DataModels </cfquery> <cftable query = "SplunkQuery" border = "1" colHeaders colSpacing = "2" headerLines = "2" HTMLTable maxRows = "500" startRow = "1"> <cfcol header="<b>Name</b>" align="Left" width=2 text="Name"/> <cfcol header="<b>Owner</b>" align="Left" width=15 text="Owner"/> ... </cftable> </body> </html>
- Finally, run the code locally in a browser at the default port of 8500. It produces a table populated with Splunk data!
As a note, the CData JDBC Drivers also support parameterized queries using the cfqueryparam element.
For example:
SELECT * FROM Account WHERE name =
