Chaos Studio
Chaos Studio Run
A visual drag-and-drop editor for designing complex chaos workflows. Build graphs of scenarios that execute in series or parallel, and measure application resilience with the Resiliency Score.
Visual Editor
- Nodes represent individual krkn scenarios
- Arrows define execution order — connect nodes to create dependencies
- Serial execution: chain nodes sequentially with single arrows
- Parallel execution: branch from one node to multiple targets
- Drag and drop to arrange the workflow visually
Node Configuration
Each node is configured exactly like a single scenario: select a registry, choose a scenario, set mandatory/optional/global parameters, and mount files.
Clone: duplicate a configured node to repeat the same scenario multiple times within the workflow.
Validation
The editor validates the workflow before execution:
- Configured nodes: green arrows and connections — ready to execute
- Unconfigured nodes: red arrows and red node border — must be configured before the workflow can run
Only fully configured nodes can be connected and executed.
Resiliency Score
Enable the Resiliency Score on a workflow to measure application resilience:
- Enable the resiliency score option on the workflow
- Mount a PromQL file — a special file containing PromQL queries uploaded via File Management
- Queries execute during the workflow and their results contribute to the final score
- View the score in the Jobs page alongside the graph run results
The PromQL file defines which metrics to evaluate (latency, error rate, throughput, etc.) and their expected thresholds. The score reflects how closely the application maintained its expected behavior under chaos.
