Make it obvious that an entire machine has stopped responding
Currently, if an entire host with stork-agent + kea-* goes offline, there is not much indication in the Stork UI. Eventually, a message will appear in the Events on the right hand side. This was as reported to me by a customer during a call where I was helping him install Stork and do some testing. The customer was sharing their screen and I did see that nothing indicated that the host was gone. Under "machines" all of the services still had a green checkmark next to them even a few minutes later.
I propose that there should be an area of the GUI dedicated to warnings regarding various critical problems (like an entire machine has gone away). The events area is fine but it is filled with all kind of messages and users quickly learn to ignore it. Maybe, in addition to an area that shows warnings, there should be some kind of monitoring page where the current health of each component (even the entire host) could be shown visually. I think this type of screen is what the customer was ultimately after.
