Retrieve last events from an Apache Camel route - events

Question

When a Camel route starts, the status of the route changes. However it happens that the route starts correctly, but there are log warning/errors during start/runtime (for example incorrect password when starting a FTP component).
These events are logged into the console/log file. I want to get these events programmatically (outside the Camel DSL). For example getEvents(routeID, typeEvent, xNumberOfEvents){}.
Are these events cached somewhere by Camel? Can I retrieve the events by something like the ManagedRouteMBean? Or should I write my own caching mechanism using the event notifier (similar to the RiderEventNotifier example) or some kind of errorhandler?
For example to following message is written to the log:
2018-10-11 22:15:24.719 WARN 3820 --- [ XNIO-2 task-12]
o.a.c.component.file.remote.FtpConsumer : Error auto creating directory:
due File operation failed: 530 This server does not allow plain FTP. You have
to use FTP over TLS.
. Code: 530. This exception is ignored.
org.apache.camel.component.file.GenericFileOperationFailedException: File
operation failed: 530 This server does not allow plain FTP. You have to use
FTP over TLS.
. Code: 530
The issue with the above is that the route start up normal. So
ManagedRouteMBean route = context.getManagedRoute(id, ManagedRouteMBean.class);
RouteError lastError = route.getLastError();
returns no error.
Also this seems not errors in the exchange, so the errorhandler or event notifiers don't intercept these messages.
I would like to intercept (and cache) such messages by routeid.

There is a way to handle these kinds of warnings/errors by the normal errorhandler by use of a so-call bridgeErrorHandler. See: http://camel.apache.org/why-does-my-file-consumer-not-pick-up-the-file-and-how-do-i-let-the-file-consumer-use-the-camel-error-handler.html
