Course Overview
- This course offers a comprehensive series of practice examinations specifically designed to prepare you for the Splunk Certified Developer Exam. It provides an essential platform for individuals aiming to validate their expertise in building, extending, and customizing Splunk applications. Through a simulated exam environment, you will confront diverse questions spanning advanced SPL, app architecture, UI development, and API interactions. The core goal is to rigorously test your understanding, identify specific knowledge gaps, and reinforce crucial concepts, ensuring you approach the official certification test with strategic readiness and confidence. Refine your time management and problem-solving skills under pressure, transforming theoretical knowledge into demonstrable expertise.
Requirements / Prerequisites
- Solid Splunk Foundation: Prior experience with Splunk Enterprise/Cloud administration, including data ingestion and basic search operations, is essential.
- Intermediate SPL Skills: Proficiency in complex search queries, statistical functions, subsearches, and lookups is required.
- Basic Programming Acumen: Familiarity with Python for custom commands, modular inputs, and API concepts is highly beneficial.
- Web Technology Fundamentals: Understanding of HTML, CSS, and JavaScript is advantageous for UI customization.
- Conceptual App Knowledge: Grasp of Splunk app directory structure and packaging principles is assumed.
- Commitment to Study: Dedication to reviewing questions, explanations, and self-research is crucial for success.
Skills Covered / Tools Used
- Advanced Search Processing Language (SPL): Master search optimization, creation of custom commands, search macros, lookup tables, data models, and various field extraction methods (`props.conf`, `transforms.conf`).
- Splunk App Architecture & Development: Deep understanding of the Splunk app directory structure, `app.conf` configurations, precedence of `default` vs. `local` directories, and best practices for app packaging and deployment.
- Dashboard and UI Customization: Expertise in Simple XML for dynamic dashboards, including advanced form inputs and data visualizations. Explore extending Splunk’s UI using JavaScript and the Splunk Web Framework for custom views and components.
- Splunk REST API & SDKs: Learn to programmatically interact with Splunk for data ingestion, search management, configuration updates, and user/role administration. Understand core Python SDK concepts for building external integrations.
- Custom Commands & Modular Inputs: Develop Python-based custom search commands to extend SPL functionality, process search results, and implement modular inputs for bringing diverse external data streams into Splunk.
- Data Ingestion & Event Processing: Solidify knowledge of source types, host, source, and index fields. Master parsing configurations using `props.conf` and `transforms.conf` for event line breaking, timestamp extraction, field extractions, and data transformation at ingest time.
- Alerting & Reporting Enhancements: Design sophisticated alerts with custom actions, effectively utilize scheduled searches, and create advanced reports with drill-downs and dynamic components essential for robust application functionality.
- Configuration File Mastery: Develop a comprehensive understanding of critical Splunk configuration files beyond `props.conf` and `transforms.conf`, including `inputs.conf`, `outputs.conf`, `indexes.conf`, `server.conf`, `web.conf`, and their impact on application behavior and performance.
- Debugging & Performance Optimization: Acquire skills in troubleshooting Splunk app issues, diagnosing search performance bottlenecks, utilizing Splunk’s internal logs, and applying best practices for writing efficient SPL and custom code.
- Security within Splunk Applications: Address security considerations in app development, including Role-Based Access Control (RBAC), data masking, secure coding practices, and managing secrets within Splunk configurations.
- Version Control Integration: Understand how Splunk app configurations can integrate with version control systems (e.g., Git) for collaborative development and deployment.
- Tools Utilized: Primarily a web browser for Splunk Web access, a text editor/Integrated Development Environment (IDE) like VS Code for reviewing code examples in explanations, and a conceptual grasp of Splunk Enterprise/Cloud environments.
