Splunk

Splunk is an enterprise-grade platform for searching, analyzing, and visualizing machine data generated by applications, infrastructure, and security systems. It ingests data from logs, metrics, events, and traces across on-premises, cloud, and hybrid environments, then normalizes and indexes that data for fast, flexible querying. Using Splunk, teams can create real-time dashboards, alerts, and reports to monitor system performance, detect anomalies, and investigate incidents.

Key capabilities include log management and aggregation, full-text search, correlation of events across multiple data sources, and advanced analytics using SPL (Search Processing Language). Splunk’s observability features support application performance monitoring, infrastructure monitoring, and distributed tracing, enabling root-cause analysis and faster incident response. Its security functionality powers SIEM use cases such as threat detection, security monitoring, and compliance reporting.
