Custom Checks notification events

NuGet Package: NServiceBus.CustomChecks (3.x)
Target Version: NServiceBus 7.x

ServiceControl exposes two integration events related to the Custom Checks plugin.

For information about how to subscribe to ServiceControl integration events, see Using ServiceControl events.

Each custom check begins in an unknown state. Once the custom checks executes and reports its status to ServiceControl the custom check will transition to a pass or fail status. External integration events are raised whenever custom checks transition into new states.

CustomCheckFailed

The CustomCheckFailed event is published if a custom check transitions from the unknown or pass state to the fail state.
