Trying to resolve an issue we see in Control Center

Been trying for a week now to get Zenoss core working. Still struggling.

Control Center itself is up. It shows 7 services with a red exclamation point, and 5 services (some overlap with the first set) which have a red dot on them.

When we begin the startup wizard, and try to specify the machine on which zenoss core is running as a device, the software doesn't appear to return. If we go instead to the main tab for entering devices, what we see are jobs pending - and never starting (talking about days of waiting).

If we try to view events, none are displayed and when we try to create one, once again, the system just sits for a very long time - this test might have ended with a timeout error.

I suspect that the issues in the services are related to the other issues.

The odd thing is that the issues in the services generally appear to be errors in health checks. Nothing so far has generated an error that I can look at and say "Oh look, that needs fixed.".

When I opened a defect ticket, I was asked whether we were using "loopback setup" but I don't know what that means, so I can't answer that question.

So far I haven't found a good troubleshooting guide, and no docs, wiki, etc. seem to mention the failing health checks.

Any suggestions on how to proceed
