Query Splunk Data as a SQL Server Database in Node.js

You can use CData Connect Cloud to query Splunk data through a SQL Server interface. Follow the procedure below to create a virtual database for Splunk in Connect Cloud and start querying using Node.js.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Splunk, allowing you to easily query live Splunk data in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to Splunk, leveraging server-side processing to quickly return Splunk data.

Configure Splunk Connectivity for NodeJS

Connectivity to Splunk from NodeJS is made possible through CData Connect Cloud. To work with Splunk data from NodeJS, we start by creating and configuring a Splunk connection.

1. Log into Connect Cloud, click Sources, and then click Add Connection

2. Select "Splunk" from the Add Connection panel

3. Enter the necessary authentication properties to connect to 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.

   
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Splunk Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect Cloud through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect Cloud. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect Cloud app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Splunk data from Node.js.

Query Splunk from Node.js

The following example shows how to define a connection and execute queries to Splunk with the SQL Server module. You will need the following information:

• server: tds.cdata.com
• port: 14333
• user: a Connect Cloud user (e.g. [email protected])
• password: the PAT for the above user
• database: The connection you configured for Splunk (Splunk1)

Connect to Splunk data and start executing queries with the code below:

var sql = require('mssql')
var config = {
	server: 'tds.cdata.com',
	port: 14333, 
	user: '[email protected]', //update me
	password: 'CONNECT_USER_PAT', //update me	
	options: {
		encrypt: true,
		database: 'Splunk1'
	}
}

sql.connect(config, err => { 
    if(err){
        throw err ;
    }
    new sql.Request().query('SELECT * FROM DataModels', (err, result) => {
        console.dir(result)
    })
        
});

sql.on('error', err => {
    console.log("SQL Error: " ,err);
})
