Historian
Insight into the Historian’s role in storing and visualizing data within the
UMH ecosystem.
2 minute read
The Historian in the United Manufacturing Hub serves as a comprehensive data management and visualization system. It includes:
- kafka-to-postgresql-v2: Archives Kafka messages adhering to the Data Model V2 schema into the database.
- TimescaleDB: An open-source SQL database specialized in time-series data storage.
- Grafana: A software tool for data visualization and analytics.
- factoryinsight: An analytics tool designed for data analysis, including calculating operational efficiency metrics like OEE.
- grafana-datasource-v2: A Grafana plugin facilitating connection to factoryinsight.
- Redis: Utilized as an in-memory data structure store for caching purposes.
This structure ensures that data from the Unified Namespace is systematically stored, processed, and made visually accessible, providing OT professionals with real-time insights and analytics on shop floor operations.
