Splunk
Splunk is a software platform used for searching, monitoring, and analyzing machine-generated big data via a web-style interface. It collects and indexes log data from various sources, enabling real-time operational intelligence, security monitoring, and business analytics. It is widely used for IT operations, security information and event management (SIEM), and application performance monitoring.
Developers should learn Splunk when working in environments that require centralized log management, real-time monitoring, or security analytics, such as DevOps, cybersecurity, or large-scale application deployments. It is particularly valuable for troubleshooting system issues, detecting security threats, and gaining insights from machine data across distributed systems.
