Is there a tool avalable to easily test that event replication between two EPiServer 11.x "boxes" function like it should?
I.e. to check that e.g. no firewalls etc. are blocking communication.
I'm not aware of any tool, but a simple way to test is to edit and publish one content in one box and see if the changes were replicated in the other box
A testing tool could be practical if you want to test without having a site up and running. I've seen (and used) various tools for this purpose. Found this old and archived repo now, that I havn't tested:https://github.com/episerver/remoteeventslistener
