Query Splunk Data as a MySQL Database in Node.js

Execute MySQL queries against Splunk data from Node.js.

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

The CData Cloud Hub 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, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to Splunk, leveraging server-side processing to quickly return Splunk data.

Create a Virtual MySQL Database for Splunk Data

You can use any MySQL client to connect to the CData Cloud Hub and create virtual databases.

  1. Connect to the CData Cloud Hub:
    mysql --host myinstance.cdatacloud.net --user admin --password
    
  2. Once authenticated, create the virtual database for Splunk:
    mysql> CREATE DATABASE splunkdb
        -> DRIVER = "Splunk",
        -> DBURL = "user=MyUserName;password=MyPassword;URL=MyURL;InitiateOAuth=GETANDREFRESH";
    

With the virtual database created, you are ready to connect to Splunk data from any MySQL client.

Query Splunk from Node.js

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

  • Host name, or address, and port: The address of your instance of the Cloud Hub (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on the Cloud Hub
  • Database name: The database you configured for Splunk (splunkdb)

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

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'splunkdb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM DataModels', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
