You can actually take advantage of that Splunk free license and be able to get through searching and looking at the different components within the Splunk environment. That free version is capped at around 500 MB a day, and there’s certain functionality you wouldn’t be able to have. So Splunk is actually licensed by the ingest rate, cost per terabyte of how much you’re ingesting at a time. Well, let’s talk a little bit about Splunk licensing. Now, in our environment here that we’re going through in the development, everything is all in one standalone system, but as your architecture and as your system grows, it’s actually going to get more complex, and you’ll have distributed different functionality for, you know, a server dedicated to a search head, maybe two servers dedicated to your indexer, and then multiple, maybe even hundreds of thousands of different forwarders installed all-around your data center or all-around your IT environment. So how does this work from an architecture perspective? Your forwarders are sending data to your indexers, and then whenever a search is created, you’re actually looking at that. In our environment, we’re only going to have one here. Say we have two indexers in our environment because we have a very large environment or because we want to have fault tolerance. We can actually have our forwarders installed on each one of those machines, and then we have our indexers. So, in architecture, let’s say that we have some different servers running all around our data center. Let’s look at an architectural view of that. The Architecture Of Splunk: Splunk Standalone Deployment It is a small application running on a server, virtual machine, or device that takes these specific log files and sends them to our indexer. Forwarder as an agent that’s going to run on devices.

Forwarder: Forwarder is what helps us get our data from our distributed environment into those Indexers.

So you’re going to be interacting with a search head and the search environment on a daily basis. This will be the graphical interface where you’re going to go in, write your queries, create message alerts, do a lot of the Splunk administration, and also, it’s going to be what you think is really the Splunk environment.

Splunk Head: Search head is a user interface where the Splunk users, and mostly even the administrators, are going to be using and configuring.

The index is what’s going to receive the log files and index those logs so that they can be searched.

Splunk Indexer: Splunk indexer is the secret sauce that actually puts your data or your log files in a searchable fashion.

Splunk has three core components: Indexer, Forwarder, Search head. So we’re going to take an approach to just look at it from a high level. Components Of Splunk:Īll right, Before we jump into the installation, it is much required to know about its architecture. Check out the products page for more information. Splunk has a variety of products for different applications. Splunk application is developed by Splunk Inc., an American technology company based in San Francisco, California. Splunk is most likely used to search, analyze, monitor, and visualize the machine data generated by workstations, servers, applications, appliances, sensors, and other assets. Splunk is a log analyzer tool that takes all the machine data as input and lets the analyst query the data on its web interface.

Let’s see how to install Splunk on a Linux platform. However, you should need to install and configure Splunk to make use of it. Splunk is one of the popular tools in the data analytics landscape. The solution to this problem is lice in a good analytics tool. The biggest challenge comes that how to process the data? How to extract the required information for a large chunk of data? How to analyze the data to extract. Then, imagine the amount of data will be generated by all the assets in an organization. Imagine, just a small device like Biometric generates how much data. Let’s take a small device like Biometric, which captures access information whenever someone swipes to log in or log out.

It’s a lot right: laptops, desktops, servers, access points, network switches, routers, firewalls, telephones, printers, biometrics, cameras, CC TVs, and these a tons of applications, services, software, interfaces to operate the organization. If you have ever been part of any organization, you know how many assets an organization has.
