Method Detail

isEnabled

boolean isEnabled()

Whether Health Check is enabled globally

setEnabled

void setEnabled(boolean enabled)

Whether Health Check is enabled globally

resolveById

Object resolveById(String id)

Resolves HealthCheck or HealthCheckRepository by id. Will first lookup in this HealthCheckRegistry and then Registry, and lastly do classpath scanning via ServiceFactory. The classpath scanning is attempted first with id-health-check or id-health-check-repository as the key, and then with id as fallback if not found the first time.

Returns:

either HealthCheck or HealthCheckRepository, or null if none found.

register

boolean register(Object obj)

Registers a HealthCheck or HealthCheckRepository.

unregister

boolean unregister(Object obj)

Unregisters a HealthCheck or HealthCheckRepository.

getCheckIDs

default Collection<String> getCheckIDs()

A collection of health check IDs.

getCheck

default Optional<HealthCheck> getCheck(String id)

Returns the check identified by the given id if available.

getRepository

Optional<HealthCheckRepository> getRepository(String id)

Returns the repository identified by the given id if available.

get

static HealthCheckRegistry get(CamelContext context)

Returns an optional HealthCheckRegistry, by default no registry is present and it must be explicit activated. Components can register/unregister health checks in response to life-cycle events (i.e. start/stop). This registry is not used by the camel context but it is up to the impl to properly use it, i.e. - a RouteController could use the registry to decide to restart a route with failing health checks - spring boot could integrate such checks within its health endpoint or make it available only as separate endpoint.

stream

Stream<HealthCheck> stream()

Returns a sequential Stream with the known HealthCheck as its source.
