Problem with eventd and monitor I had resolved - it was disabled ipv6 in sysctl by my policy. But I all the same reciev:

Service is temporarily unavailable. Please contact DataFabric Manager server administrator. You will be redirected to login page now.

Were all the DFM services (monitor, eventd, server, sql, watchdog, http, schedular) started?

If not can you share the logs when you try to start dfm services.

Thanks
