Splunk Products

Splunk is available in three different versions.

  • Splunk Enterprise
  • Splunk Light
  • Splunk Cloud

Splunk Enterprise

Splunk Enterprise edition is used by large IT business. It helps you to gather and analyze the data from applications, websites, applications, etc.

Splunk Cloud

Splunk Cloud is a hosted platform. It has the same features as the enterprise version. It can be availed from Splunk or using AWS cloud platform.

Splunk Light

Splunk Light is a free version. It allows search, report and alter your log data. It has limited functionalities and feature compared to other versions.

Splunk Architecture

Here, are fundamental components of Splunk architecture:

Universal Forward (UF):

Universal forward or UF is a lightweight component which pushes the data to the heavy Splunk forwarder. You can install Universal Forward at client side or application server. The job of this component is only to forward the log data.

Load Balancer (LB):

Load balancer is default Splunk load balancer. However, it also allows you to use your personalized load balancer.

Heavy forward (HF):

Heavy forward is a heavy component. This Splunk component allows you to filter the data. Example: collecting only error logs.

Indexer (LB):

Indexer helps you to store and index the data. It improves Splunk search performance. By default, Splunk automatically performs the indexing. For example, host, source, and date & time.

Search head (SH):

Search head is used to gain intelligence and perform reporting.

Deployment Server(DS):

Deployment server helps to deploy the configuration. For example, update the UF configuration file. We can use a deployment server to share between the component we can use the deployment server.

License manager (LM):

The license is based on volume & usage — for example, 50 GB per day. Splunk regular checks the licensing details.

Applications of Splunk

Problem Statement: Mac-Donald had no clear visibility into what offers work best.

  • Offer type ( For example 20% off)
  • Cultural differences at a region level
  • Time of Purchase
  • Device used by the customer
  • Revenue generated per order

They needed insight into consumer behaviors and customer response.

The entire process using three types of Data source

  1. Order placed in Mac Donald Outlet
  2. Order placed in the Mobile Application
  3. Order places using the Web Application

Now the process carried from one step to other as mention in the below-given diagram.


Input Data moves to Parsing stage,


In Parsing Stage, relevant data is converted into events:

  • Customer Region
  • Revenue per order
  • Time of Order (Morning, Afternoon, Evening, Night)
  • A device used by customers (Mobile, PC, Tablet)
  • Discount Coupons applied

Indexing stage

In this stage, events are sorted and indexed for storage based on:

  • Sales by Geographical location
  • Order Revenue
  • Time of order (Morning, Afternoon, Evening, Night)
  • Device use by the customer
  • Coupon offered applied

Search Head

It is used to gain intelligence and perform reporting.

Mac- Donald used it to get the following information:

  • Which sales offer works best in which geographical location?
  • How does customer behavior changes in order revenue?
  • What is the best time to apply burger or combo offers?

How Splunk Helped?

  • Show all the order coming from across the specific region in real time.
  • Determine how different promotional offers are impacting in real-time
  • Monitor the performance of Mac Donald's in-house developing point of sale systems.

  • Analyzed the speed of different payment modes
  • Determine error-free payments mode

Best Practices of using Splunk

  • You should test the index so you can quickly perform the test.
  • There are specific fields you must get right at index time. Everything else you can create/modify only after indexing.
  • Event breaking happens automatically in spunk, so it's important to check that Splunk correctly detected the beginning and end of an event.
  • Splunk can automatically detect the time stamp. However, if your log format has a differ timestamp you need to configure the timestamp.
