Splunk tutorial for beginners - Splunk training - Splunk video course - Class 1 Let us see, what is Splunk and Have you heard the word Splunk? :- Splunk is a software or tool that is usedto analyze the machine data. But have you ever thought that, why do we have to analyze the machine data? You must be aware of the exponential growth in machine data over the last decade. This was mainly because of the growing number of machines and the usage of IoT devices. And analyzing the data is needed because the solution to the different problem is hidden in machine data. Analyzing this machine data will help us to understand the customer behaviors and their will, in turn, help us to provide better service. This machine data will help us to alert the system admins about any security issues and system failures. Analyzing machine data also helps us to improve machine functionality. However, analyzing machine data is not a simple task. So, how do we do that? Let us see, how to do that? Consider that you are working as a system administrator in some organization. In an organization, the data can be generated from different sources, such as sensors, network devices, cloud services, internet of things and mobile services. And the data generated from these resources will be in the form of unstructured machine data. For example, machine data looks something like this. Let us say, failure occurred on any of the one systems and you have to find the solution for it. It will be very difficult for you to findout, in which step the hardware failed the program. Machine data is: Complex to understand In an unstructured format and Not suitable for making analysis/visualization So, what do you think, how this can be resolved? In this case, we need a tool that understands machine data and help us in identifying where exactly the hardware or software has failed. Ad we discussed already, this can be resolved by using Splunk. Splunk is a tool in which the machine data is processed to extract the human readable form of data. This will help you to analyze the problems. Whenever you are looking for state of any software or hardware, you will search for logfile which will help us to understand the state of the software. Splunk can be defined as a Google for log files. That is, Splunk makes machine data available to IT infrastructure. The Primary components of Splunk are: forwarders, indexers and search heads. Forwarders are responsible for collecting the data and forwarding it to other Splunk instances or indexers. The indexers are the place where the data is stored. However, we cannot just access the data from indexers, we need to have search heads which will help us to analyze, visualize and report the data. Splunk will help the user to leverage the machine data in: Analyzing the system performance Identify the failure conditions in the system Monitor the business matrix Search and investigate a reason Helps in visualizing the data and creating dashboards of results It can also store the data for future references Now, let us see how Splunk works? We have a data that is stored in machines which can be in form of logs, databases, views or API clauses. On the other hand, we have users who act as information dividers from various sources. The business operations need graphs, images, pivots, and dashboards to make better decisions for business. So, what you think, what acts as a bridge between data and users. Yes, it is data indexes. Or you can think that, it is a table of databases. And this is how the data is stored in the machines. Once we store the data, we can extract the data using search processing language or SPL. All the data in the machine will be now stored in the form of events. Once this data is retrieved from the machine you can edit, calculate or concert according to your needs. This technology is not only easy to implement but also provides a wide spectrum of services to its users. Some of those are, Indexing data Facilitates searching and investigating Mapping knowledge to search Scheduling alert Prepare and share Splunk reports All these days, we have seen storage devices get better and better over the years, we have seen processors become more efficient with every aging day, but not data movement. Splunk is a handy tool to do this. You might be wondering why organizations are opting for Splunk. .Thank you for watching this video. Subscribe Our Channel and Press The Bell Icon:
