    What Is Splunk?

    Splunk is a software platform that helps organizations search, monitor and analyze data from any source. Splunk is used to monitor and troubleshoot problems with applications, servers, and networks. Its main selling point is real-time processing because processors and storage devices have improved steadily over the years, but data mobility has not. The bottleneck in most organizational procedures continues to be this technique, which has not advanced.

    Splunk's engine is blazingly quick and produces outcomes in a flash. Any problem can be resolved by performing an efficient root cause analysis and solving it immediately. Splunk transforms valuable machine-generated data into effective operational intelligence using reports, charts, and alerts. That explains the “what is Splunk?” part; let’s dig deeper into more Splunk fundamentals now.

    What does Splunk mean? The word "splunking," which refers to exploring caves, inspired the name Splunk. By caves, its creators meant Big Data and machine-generated data.

    Splunk Architecture

    Splunk architecture

    1. Universal Forwarder (UF): A light component helps move the data to the powerful Splunk forwarder. This element's main responsibility is to simply forward server-generated log data. Installing Universal Forward on the client side or the application side is simple.
    2. Load Balancer (LB): In terms of computers, load balancing improves how workloads are distributed among various computing resources. They are responsible for distributing network or application traffic among a group of servers.
    3. Heavy Forwarder (HF): It is a hefty element. By using this Splunk component, you can filter the data. For example, it will assist in gathering only error logs.
    4. Indexer: An indexer's main responsibility is to store and index the filtered data. It aids in enhancing Splunk's functionality. Splunk automatically implements indexing for hosts, sources, dates, and times.
    5. Search Head (SH): It merely acts as a Splunk instance that assists in delivering searches to the other indexers; it typically lacks an instance of its own. It is mostly employed to gather intelligence and carry out reporting.
    6. Deployment Server (DS): When upgrading the UF (Universal Forwarder) configuration file, for example, it aids with the deployment of the configuration. A DS can be used to transfer data between the parts.
    7. License Master (LM): A Splunk Enterprise state that is under the supervision of a License Master is known as a license slave. The license is dependent on both usage and quantity.
