To provide custom application information, you can register Spring beans that implement the InfoContributor interface. CORS support is disabled by default and is only enabled once the management.endpoints.web.cors.allowed-origins property has been set. Read more information about creating alert notifications. Most applications include instrumentation such as error handlers and performance counters that log performance and detailed error information, this might be sufficient instead of returning additional information from a health verification check.
