Application Health Indicators
IPF flow starter provides a spring backed health actuator, this is responsible for updating the health endpoint of the application.
The health of the app is built up from existing spring health indicators, i.e. mongo, diskspace, etc, plus the health of the connector transports.
Connector Transports
The IPF connectors emit one of TransportAvailable, TransportUnavailable, TopicUnavailable or CircuitBreakerStateChanged which are then converted into a health state by the ConnectorEventProcessor.
Health Reports
Reports the general health of the app by aggregating all health indicators.

If we don’t enable health-check it will raise TransportAvailable by default.
Application Configuration
To enable spring endpoints add the following enablers to your application config.
management.endpoint.health.probes.enabled=true management.health.livenessState.enabled=true management.health.readinessState.enabled=true
