Typical user scenario, The user would install litmus. This would in-turn install Portal and Agent on the self cluster. Using the portal user can create/schedule new chaos workflows on the Agents and observe the results from here. User can also connect more clusters to the portal, and use the Portal as single window pane for cross cloud chaos management.

ChaosResult resource holds the results of a ChaosExperiment with a namespace scope. It is created or updated at runtime by the experiment itself. It holds important information like the ChaosEngine reference, Experiment State, Verdict of the experiment (on completion), salient application/result attributes. It is also a source for metrics collection. It is updated/patched with the status of the experiment run. It is not removed as part of the default cleanup procedures to allow for extended reference.

- **Chaos Probes**<br />

Litmus probes are pluggable checks that can be defined within the ChaosEngine for any chaos experiment. The experiment pods execute these checks based on the mode they are defined in & factor their success as necessary conditions in determining the verdict of the experiment (along with the standard “in-built” checks).

#### What is a Chaos Workflow?

2323
A chaos workflow is much more than a simple chaos experiment. It supports the user in defining the expected result, observing the result, analysing the overall system behaviour, and in the decision-making process if the system needs to be tuned for improving the resilience.
2424
LitmusChaos provides necessary infrastructure to develop, use, and manage chaos workflows for a typical development or operations team. Teaming and GitOps features of Litmus help greatly to collaborate the chaos workflows management within the teams or software organisations.
