The Cluster Manager
The cluster manager is a HEAT administration tool that provides a web interface for monitoring and managing your HEAT platform. You can access it by navigating to /main/monitoring on any modern HEAT environment.

The web interface offers insight into the current level of load and whether the environment is in a healthy state, it also provides a basic overview of core entities such as sessions, data sources, templates and configurations.
The cluster manager is not designed for authoring end-to-end HEAT-based solutions, and further tools or API access may be necessary to fully elucidate any data journeys.
