inviso

Inviso is a lightweight monitoring and visualization tool designed for Hadoop clusters. It enables administrators and developers to search through job histories, analyze performance metrics, and monitor cluster resource utilization through an intuitive web interface. ## Key Features - **Job Search** — REST API and ElasticSearch integration for querying Hadoop job histories and correlating Pig and Hive scripts. - **Performance Visualization** — Web UI to visualize job performance metrics and identify bottlenecks. - **Cluster Utilization Monitoring** — Tracks and displays cluster resource usage over time. - **Extensible Indexing** — Python scripts to index job configurations into ElasticSearch, supporting pub/sub models for distributed event handling. - **Task Log Linking** — Requires Hadoop log aggregation to link directly to task logs for deeper debugging. ## Philosophy Inviso prioritizes simplicity and lightweight deployment, providing essential Hadoop cluster observability without heavy infrastructure overhead.
