Rudder 3.0: Status reporting

Status reporting

✔ Display an overview of all states for a Rule✔ Proportional to number of nodes✔ Proportional to number of configurations

✔ Drilldown by node or by component✔ Display recent changes (repairs) over time✔ List recent changes (repairs)



Status reporting
