Comment 3 Pavol Brilla 2020-10-30 10:14:29 UTC 
Instead of spam, user can see failed token info in Events.


And engine.log will contain only: 
No prometheus URL provided. Statistics won't be fetched for provider 'rhvintegration' This error will not be logged again until connectivity is broken again after being successfully restored.
