STORM-69: Storm UI Visualizations for Topologies
Adds a directed-graph topology visualization to the topology page using
storm's metrics and a javascript library called 'Arbor.js' released under the
BSD license.
Features:
- Colors to represent spouts and bolts: spouts are blue, bolts are colored
between green and red depending on their capacity consumption
- Width of lines between components represents the flow of tuples going
between the components relative to the other visible streams.
- Stream selector: Select the streams you want to see.
- Tuple count, name, and latency labels on nodes and edges
