Splunk and Kibana are two popular frameworks used for log management, monitoring, and data visualization. Splunk is a proprietary platform that collects, indexes, and analyzes machine-generated data such as logs, events, and metrics from various sources. Kibana is an open-source visualization tool that works with the Elasticsearch data store to create interactive dashboards, charts, and visualizations from indexed data. Both frameworks help organizations gain insights, troubleshoot issues, and monitor system performance in real-time.
