• What is Splunk? Key Benefits and Features of Splunk - Fortinet

  Splunk is an advanced and scalable form of software that indexes and searches for log files within a system and analyzes data for operational intelligence.The software is responsible for splunking data, which means it correlates, captures, and indexes real-time data, from which it creates alerts, dashboards, graphs, reports, and visualizations. This helps organizations recognize common data patterns, diagnose potential problems, apply intelligence to business operations, and produce metrics. Splunk’s software can be used to examine, monitor, and search for machine-generated big data through a browser-like interface. It makes searching for a particular piece of data quick and easy, and more importantly, does not require a database to store data as it uses indexes for storage. [...] ## A Brief History Of Splunk Splunk was founded in 2003 by Rob Das and Eric Swan, who aimed to provide a solution to the “information caves” that organizations struggled with. The name Splunk came from the term “spelunking,” which is a term describing the hobby of exploring caves. The co-founders developed the technology to create a search engine that could log files stored within a system’s infrastructure. They aimed to market it in bulk, enabling the technology to be deployed in any use case. Splunk’s first version launched in 2004 and gradually grew in popularity with organizations, which increasingly purchased enterprise licenses. ## Why Do We Need Splunk?

• What Is Splunk? The Complete Overview of What Splunk Does

  How much does Splunk cost? Splunk is an enterprise-grade platform built for complex, high-volume data environments, which means it may carry a higher price point than simpler tools. For most, the price is an excellent ROI: Splunk offers significant value through real-time analytics, scalability, and flexibility. Splunk provides multiple pricing models (including ingestion-based, workload-based, and predictive options) to align with different deployment types, data needs, and budgets. Who should use Splunk — and who shouldn’t? Splunk is ideal for enterprises and organizations that need to monitor, secure, or analyze large-scale machine data environments in real time. It may not be the best fit for lightweight monitoring needs or single-use deployments with minimal data variety. [...] Supported platforms: Windows, Linux, Unix. Data formats: Handles syslog, CSV, JSON, XML, and custom log formats. Configuration: Uses inputs.conf to specify monitored files or directories; supports SSL encryption for secure data transmission. Scaling: Multiple Universal Forwarders can send data to a single or clustered set of indexers for load balancing. ### Search Processing Language (SPL) Splunk’s proprietary query language for searching, filtering, and transforming machine data. Syntax: Command-based, similar to Unix pipelines (e.g., `index=web_logs | stats count by status_code`). Key commands: `search, stats, eval, rex, table, sort.` Advanced functions: Supports subsearches, lookups, and custom macros; enables complex analytical queries for real-time and historical data. [...] ## How does Splunk work? Splunk processes machine data through a structured pipeline. Here’s how the Splunk data pipeline works: Forwarders: Collect data from remote systems. Indexers: Process and store the data for fast retrieval. Search Head: Enables users to search, analyze, and visualize the data. Now, let's break these components down. ## Splunk data pipeline: Technical breakdown Splunk’s architecture follows a distributed model, separating data ingestion, indexing, and search for scalability and performance. ### 1. Universal forwarder (UF) The Splunk UF is a lightweight agent installed on source systems to securely collect and forward raw event/log data.
